1. Introduction
1.1. Overview
The Parani-BCD110 is Bluetooth OEM SMD/DIP module combining antenna for OEM
manufactures who want to implement Bluetooth functionality with their products cost effectively
and also in timely manner. Parani-BCD110 has a built in antenna to lower the overall cost while
benefit from the Parani-BCD110’s field-proven standard SPP firmware provided with no additional
cost. In addition, it is provided with the firmware used for Sena I/O (Input/Output) profile and SCO
(synchronous Connection Oriented) connection.
The Parani-BCD110 supports Class1 Bluetooth transmission level for longer communication
distance typically ranges from 200m up to 1000m.
The Parani-BCD110 is provided with the firmware which not only conforms to Bluetooth
v2.0+EDR but also supports SPP (Serial Port Profile), Sena I/O Profile and SCO connection by
default. The SPP firmware supports up to 7 simultaneous multiple connection which can compose
the maximum Bluetooth piconet and is designed to work out-of-box for real world SPP
applications such as POS (point-of-sales), industrial automation, remote metering and other
various applications. Sena I/O Profile can be applied for remote controller or temperature/light
control system without any additional interface by supporting DIO input/output and AIO input. In
addition, SCO connection facilitates the implementation of Bluetooth voice communication using
starter kit and simple PCM interface mentioned at Appendix F.
Optionally, the Parani-BCD110 can be supplied with only software stack up to HCI level so entire
Bluetooth stack runs on the host side for the application such as USB dongles for computers.
Besides, OEM manufacturers can even develop and embed their own firmware into the ParaniBCD110.
The Parani-BCD110 is fully qualified with Bluetooth v2.0+EDR specification so OEM
manufacturers can save cost and time for overall OEM product certifications, which makes the
Parani-BCD110 ideal solution for larger volume and cost sensitive applications.
This document deal with the introduction, configuration and directions of the Parani-BCD110
module.

Note
*:
Bluetooth v2.0 supports improved AFH function. AFH function is to mitigate the interference
between WiFi and Bluetooth radios by automatically avoiding the active WiFi channel from
Bluetooth link. However, AFH dos not provide a complete solution making WiFi and Bluetooth work
together in harmony. It is highly recommended for users to test their wireless system enough before
deployment since the overall system performance is affected by various environmental factors
such as distance between them.

3.3. Data Bit
The Parani-BCD110 supports only 8 data bit. But if both master device and slave device are
of Parani-SD, Parani-ESD or Parani-BCD or Parani-MSP1000 series, Parani series devices
support 7 data bit and even/odd parity by setting both Parani series devices to 8 data bit
none parity. But 7 data bit and none parity cannot be supported even if both master device
slave device are Parani series devices.

3.4. Hardware Flow Control
The Parani-BCD110 plugged into its host system transmits data from host to the other side
Bluetooth device. This data is saved temporarily in the internal buffer of Parani-BCD110 and sent
repeatedly until the transmission is completed packet by packet. When the radio transmission
condition is not good enough to send data promptly, it can cause a transmission delay. If the
host sends more data when the buffer is full, buffer overflow will make Parani-BCD110
Sena Technologies, Inc
16
malfunction consequently. In order to prevent this buffer overflow, Parani-BCD110 works as
follows.
When using hardware flow control, Parani-BCD110 disables RTS so that it stops receiving any
further data from the host when the buffer becomes full. RTS will be re-enabled again to begin
receiving data from the host when the buffer has created more room for more data.
When hardware flow control is not being used, the Parani-BCD110 clears the buffer to secure
room for the next data when the buffer becomes full. This can mean a loss of data may occur.
As the transmission data becomes large, the possibility of data loss becomes greater.
For large data transmissions, the use of hardware flow control is highly recommended. (Not
support flow control in Multi-Drop Mode.)
3.5. Remote Configuration Mode
The Parani-BCD110 supports remote configuration mode. After connecting the Parani-BCD110
through Bluetooth, send three remote escape sequence character (default: ‘-‘, 45) for remote
configuration mode. Then, the Parani-BCD110 will enter remote configuration mode. You have to
enter the password with “AT+PASS” command. The default password is “0000”.
After the password authentication, the remote configuration of the Parani-BCD110 is available
with the “Remote Configuration Enabled” message displayed. After password authentication fails
three times, remote configuration mode will close. If there is no input for two minutes after entering
remote configuration mode, remote configuration mode will also close. (However, if periodic
sampling or change detection sampling is active, auto close function of the remote control mode will be
inactive.)
The password for remote configuration mode is configurable using “AT+CHPASS” command. Its
maximum length is 8. If it is not set, remote configuration mode is not available.
AT+CHPASS=<values><CR>
* AT commands such as “ATH”, “ATO”, “ATD”, “AT+BTSCAN”, “AT+BTINQ?”, “AT+BTCANCEL”,
“AT+IOCONNECT”, “AT+IODISCONNECT”, “AT+SCOCONNECT”, “AT+SCODISCONNECT” are
not performed at remote configuration mode.

3.6.1. ParaniWIN
ParaniWIN is a program that runs on Microsoft Windows for the configuration of Parani-BCD110.
Before configuring Parani-BCD110 with ParaniWIN, user needs to know Bluetooth connection
modes and Parani-BCD110 operation modes as following.
A Bluetooth device can play a role as a master or slave. Master tries to connect itself to other
Bluetooth devices, and slave is waiting to be connected from other Bluetooth devices. A Bluetooth
connection is always made by a pair of master and slave devices. There are two modes in slave,
Inquiry Scan or Page Scan mode. It can be in both or either of them. It waits for a packet of
inquiry from other Bluetooth device in Inquiry Scan mode and waits for a packet of connection
from other Bluetooth device in Page Scan mode. Every Bluetooth device has its unique address,
called BD (Bluetooth Device) address, which is composed of 12 hexa-decimal numbers.
To utilize these two Bluetooth connection mode efficiently, Parani-BCD110 supports four
operation modes as in table 3-3.
Table 3-3 The Parani-BCD110 Operation Modes
Mode
Description
Mode0
Parani-BCD110 is directly controlled by AT commands.
Parani-BCD110 does not anything when power on or software reset and waits for AT
command input. Neither master nor slave is assigned to Parani-BCD110 in mode0. User
can change the configuration parameters and perform functions such as search and
connection through AT commands in this mode. Parani-BCD110 must be in Mode0, when
it is directly configured or controlled by AT commands.
The factory default is set to Mode0.
Mode1
Parani-BCD110 tries to connect the last connected Bluetooth device.
Parani-BCD110 in Mode1 is to be a master and tries to connect the last connected
Bluetooth device in SPP and I/O profile. It also tries the SCO connection after SPP
connection is established with SCO Enable (ATS84) enabled. Unlike SPP, I/O and SCO
connection is available only in single connection mode.
If the last connected Bluetooth device in SPP profile is different from the last connected
Bluetooth device in I/O profile, Parani-BCD110 tries to connect to not the latter but the
former in both SPP and I/O profile.
Once Parani-BCD110 successfully connects to the target device in Mode0, it is possible
to change the operation mode to Mode1 from Mode0. Parani-BCD110 stores the BD
Sena Technologies, Inc
18
address of the Bluetooth device which is connected for the last time at specific S-registers
such as ATS46, ATS54, ATS55, ATS56, ATS57, ATS58, ATS59 in SPP profile and ATS72
in I/O profile. Without direct connection to the target device in Mode0, it is possible to
change to Mode1 by setting the S-register for the last connected device with AT
command.
When Parani-BCD110 is initially used or hardware reset is committed, there is no BD
address stored in Parani-BCD110. In this case, it is impossible for Mode1 to work properly,
so the mode change to Mode1 cannot be made.
Parani-BCD110 in Mode1 cannot be discovered or connected by other Bluetooth devices.
Mode2
Parani-BCD110 waits for a connection from the last connected Bluetooth device.
Parani-BCD110 in Mode2 is to be a slave and waits for the connection only from the last
connected Bluetooth device in SPP and I/O profile. It also waits for the SCO connection
after SPP connection is established with SCO Enable (ATS84) enabled.
If the last connected Bluetooth device in SPP profile is different from the last connected
Bluetooth device in I/O profile, Parani-BCD110 waits for connection from not the latter
but the former in both SPP and I/O profile.
Mode2 is available only in single connection mode. Once Parani-BCD110 successfully
connects to the target device in Mode0, it is possible to change the operation mode to
Mode2 from Mode0. Without direct connection to the target device in Mode0, it is possible
to change to Mode2 by setting the S-register for the last connected device with AT
command.
When Parani-BCD110 is initially used or hardware reset is committed, there is no BD
address stored in Parani-BCD110. In this case, it is impossible for Mode2 to work properly,
so the mode change to Mode 2 cannot be made.
Parani-BCD110 in Mode2 cannot be discovered by any other Bluetooth device nor
connected to Bluetooth devices other than the last connected device whose BD address
is stored at specific S-registers such as ATS46 in SPP and ATS72 in I/O profile.
Mode3
Parani-BCD110 waits for the connection from any other Bluetooth devices. In Mode 3 the
Parani-BCD110 is discoverable and can be connected to by other Bluetooth devices.
Running ParaniWin, the Serial Port Setting window appears as below:

Parani-BCD110 supports two security options, Authentication and Encryption. If you enable the
Authentication option, you must also enter a Pin Code value. If the authentication is enabled, the
connection, between the Master and Slave device must share the same Pin Code. In case that
Parani-BCD110 connects to another Bluetooth device, that requires authentication, you must
know its Pin Code. In general, most Bluetooth devices have a pin code of 1234 or 0000. The Pin
Code of Parani-BCD110 is 1234 at default.
If you check Encryption option, the Parani-BCD110 will encrypt packets and sent to the device.
If one requests the encryption, the other consents to it. The Encryption options works well in case
Sena Technologies, Inc
21
that only one of the devices between Master and Slave use the Encryption option.
Parani-BCD110 has 4 response messages, ‘OK’, ‘ERROR’, ‘CONNECT’, and ‘DISCONNECT’. In
some cases, these responses can affect the host system unexpectedly. To prevent this, user can
set the Command response to ON or OFF.

4. SPP (Serial Port Profile)
4.1. Overview
Parani-BCD110 conforms to field-proven standard SPP (Serial Port Profile). This chapter deals
with multiple connections out of SPP functions in detail.
Parani-BCD110 supports multiple connections up to 7 slave units. There are two types of multiple
connection modes: Multi-Drop Mode and Node Switching Mode.
Figure 4-1 Multi-Drop Mode
In Multi-Drop Mode a master unit can connect to maximum 7 slave units at the same time and
they transfer data bi-directionally as in Figure 4-1.
Figure 4-2 Node Switching Mode
In Node Switching Mode, the master unit maintains multiple connections with maximum 7 slave
units but only one connection with one slave unit is active and data is transferred as shown in
Figure 4-2. After connected to slave, master acts in command mode. Active slave is selected by
AT commands.

4.2. Configuration
All the slaves should be in the status of waiting for connection either in Mode 2 or Mode 3 and
the master unit tries to connect to the slave units. The master unit needs to be configured to work
in a multiple connection mode using AT+MULTI,x command, which makes master reboots after
execution.

4.4. Notes
When large data exchange occurs in Multi-Drop mode without flow-control enabled, the master
unit may experience data loss. It may also experience occasional disconnections and/or system
rebooting especially when bi-directional communication happens. It is strongly recommended to
perform extensive performance test before any real world field applications.
The master unit would try to connect all slave units specified by S-register 46, 54, 55, 56, 57, 58
and 59. If non-existing or inactive slave addresses are entered in these S-registers, the overall
performance will degrade due to frequent connection trials to non-existing/inactive slaves. It may
also force disconnections for overall performance and output disconnect messages repeatedly.
Node-switching mode provides nearly equivalent performance as single connection mode. It is
always recommended to use flow-control for both of Multi-Drop Mode and Node Switching Mode.

5. Sena I/O Profile
5.1. Overview
Parani-BCD110 provides the method to use the inputs and outputs pins embedded in the module.
It has total 12 I/O pins which consist of 2 AIO pins and 10 DIO pins. Out of 10 DIO pins, only 5
pins except the pins assigned to DCD, DTR, DSR, FACTORY_RESET and MODE can be used for
DIO. The AIO pins can be used for input only and the DIO pins can be used for input and output
according to the I/O configuration.
The I/O pins can be utilized through Bluetooth connection in two ways: remote sampling and
synchronization. The synchronization through I/O Profile connection is available only in single
connection mode.
This chapter describes the usage of the I/O in Parani-BCD110, separated by sampling and
synchronization.

Sampling means reading the status of the I/O pins in remote Parani-BCD110. It is implemented
in the Remote Configuration mode which is based on SPP connection as shown Figure 5-1.
Figure 5-1 I/O Sampling
Sena Technologies, Inc
31
As shown Figure 5-2, synchronization means that the I/O status of two Parani-BCD110s on I/O
profile connection are synchronized with those of each other. It is committed in various ways
according to the configuration of synchronization for each pin.
Figure 5-2 DIO Synchronization
5.2. I/O Configuration
To use the inputs and outputs pins embedded in the module, their functions are set in advanced.
The AT command below can be used to change I/O configuration. Changes of I/O configuration
are applied after rebooting.
AT+SETIO=<value1><value2><value3><value4><value5><value6><value7><CR>
, where value1 ~ value2 are for AIO configuration and their value can be 0 or 1 and value3 ~
value7 are for DIO and their value can be 0 ~ 4.
The meaning of the values of AIO and DIO are as below and “AT+IOINFO” displays the current
I/O settings.

5.3. I/O Sampling
The I/O status can be monitored and controlled using the AT commands. The I/O status of remote
device can be monitored and controlled using Remote Configuration on SPP connection, too.
Please refer to the 3.5 Remote configuration Mode for more details regarding Remote
Configuration.
5.3.1. Queried Sampling
The digital and analog I/O status of Parani-BCD110 can be monitored and controlled using the
AT commands either locally or remotely.
AT+DIO?<CR>
The AT+DIO command can be used to read the digital I/O line values. Return value is a
combination of 0 (Low) and 1 (High).
It can also be used to set the digital output lines.
AT+DIO=<value1><value2><value3><value4><value5><CR>
, where value1 ~ value5 can be 0(Low) or 1(High) in each.
AT+AIO?<CR>
The analog input values can be read using the AT+AIO command. The unit of return value is
Voltage and the range is between 0 and 1.5V approximately.
Users can monitor and control the status of remote Parani-BCD110 on SPP connection using
Remote Configuration as below:

5.3.2. Periodic Sampling
The digital and analog I/O status of Parani-BCD110 can be monitored periodically.
AT+IOPS=<value><CR>
, where value is the I/O sampling period between 0 and 3600 in second. If set to 0, Periodic
sampling is disabled.
The I/O status of remote Parani-BCD110 on SPP connection can be monitored in the remote
Periodic Sampling like the remote Queried Sampling by using the Remote Configuration.

5.3.3. Change Detection Sampling
The digital I/O status of Parani-BCD110 can be monitored whenever a monitored digital I/O pin
changes state.
AT+DIOCDS=<value><CR>
Set DIO change detection sampling mode. If set to 0, DIO change detection sampling is disabled.
The DIO change detection sampling and the Periodic Sampling can be set and used at the same
time.
The DIO status of remote Parani-BCD110 on SPP connection can be monitored in the remote DIO
Change Detection Sampling like the remote Queried Sampling by using the Remote Configuration.

5.3.4. AIO Change Detection Sampling
The AIO change detection sampling is difficult because the value of AIO varies continuously. For
this reason, the AIO values are not sampled whenever AIO value changes. Instead, sampling is
committed when AIO value is out of range specified at the Falling edge and Rising edge. That is,
the analog I/O values of Parani-BCD110 can be monitored when AIO value falls down below the
Falling edge or rises up above the Rising edge immediately.
AT+AIOCDS = <value, AIO0 Rising edge, AIO0 Falling edge, AIO1 Rising edge, AIO1 Falling
edge><CR>
The AT+AIOCDS command can be used to set AIO change detection sampling mode. The value
ranges from 0 to 10. The less value is, the more often the AIO values are sampled. If it is set to
0, the AIO change detection sampling is disabled.
The AIO value of remote Parani-BCD110 on SPP connection can be monitored in the remote AIO
Change Detection Sampling like the remote Queried Sampling by using the Remote Configuration.
* If the Rising edge is greater than the Falling edge, the AIO value will be monitored when AIO
value is between the Falling edge and the Rising edge.
Example of AIO Change Detection Sampling
at+aiocds=1,15000,0,15000,0

AIO0 : <1.5096>, AIO1 : <1.4721>, DIO:<00000>
AIO0 : <1.5032>, AIO1 : <1.4721>, DIO:<00000>
5.4. DIO Synchronization
The Parani-BCD110 supports that the both sides of I/O profile connection synchronize their DIO
status. The DIO Synchronization means that one device on I/O profile connection adjusts its DIO
status according to the DIO status of the other device or vice versa. It is available only when
both devices are connected on the I/O profile.
The I/O profile connection is possible when both devices are in single connection mode and have
at least one DIO pin which is set to digital I/O.
AT+IOCONNECT<bdaddr><CR>
The AT+IOCONNECT command can be used to connect on the I/O profile to the device which is
designated at <bdaddr>.
Both Parani-BCD110s of the I/O profile connection are synchronized in two ways – Input/Output
synchronization and Output/Output synchronization - according to the I/O configuration and DIO
synchronization configuration. The I/O configuration is specified by the AT+SETIO=<values>”
command and the DIO synchronization by the “AT+IOSYNC=<value>” command.

AT+ IOSYNC =<value1><value2><value3><value4><value5><CR>
, where <value1>~<value5> can have a value between 0 and 3 as below:
DIO Synchronization Configuration
0 Disabled
1 Synchronization Input
2 Synchronization Output
3 Synchronization Input/Synchronization Output
The output status of a DIO output pin with Synchronization Output at one device changes
according to the DIO input status of corresponding DIO input pin with Synchronization Input at
the other device. A DIO output pin with Synchronization Input/Synchronization Output can be
used as Synchronization Input or Synchronization Output.
“1 Synchronization Input” and “2 Synchronization Output” is explained at 5.4.1 Input/Output
Synchronization in detail. “3 Synchronization Input/Synchronization Output” is described at 5.4.2
Output/Output Synchronization in detail.

* Changes of DIO Synchronization configuration are applied without rebooting.
5.4.1. Input/Output Synchronization
The Input/Output Synchronization means the synchronization between two Parani-BCD110s
which are connected on I/O profile - one is set as Digital Input for I/O configuration and the other
is set as Digital Output.
For example, let’s assume that there are two Parani-BCD110s connected on I/O profile which are
BCD1 and BCD2. The DIO1 of BCD1 is set as Digital Input for I/O configuration and
Synchronization Input for DIO Synchronization Configuration. The DIO1 of BCD2 is set as Digital
Output for I/O Configuration and Synchronization Output for DIO Synchronization Configuration.
When DIO1 status of BCD1 changes, DIO1 status of BCD2 is synchronized as to DIO1 status of
BCD1.
5.4.2. Output/Output Synchronization
The Output/Output Synchronization means the synchronization between two Parani-BCD110s
which are connected on I/O profile and whose I/O configuration are Digital Output.
For example, let’s assume that there are two Parani-BCD110s connected on I/O profile which are
BCD1 and BCD2. The DIO1 of BCD1 is set as Digital Output for I/O Configuration and
Synchronization Input/Synchronization Output for DIO Synchronization Configuration. The DIO1
of BCD2 is also set as Digital Output for I/O Configuration and Synchronization
Sena Technologies, Inc
36
Input/Synchronization Output for DIO Synchronization Configuration. When DIO1 status of BCD1
changes, DIO1 status of BCD2 is synchronized as to DIO1 status of BCD1. In same way, DIO1
status of BCD1 is synchronized with DIO1 status of BCD2, too. In case of Output/Output
Synchronization, of two Parani-BCD110s connected on I/O profile, when one device changes in
DIO status by AT command, the other device is automatically synchronized.
* Each 5 DIO pin separately works. That means, each DIO pin can be set as Input/Output
Synchronization or Output/Output Synchronization.
Table 5-4 and Figure 5-3 below describes how both Parani-BCD110s of the I/O profile
connection works according to I/O Configuration and DIO Synchronization Configuration.

6. SCO (Synchronous Connection Oriented)
6.1. Overview
There are two Bluetooth link types according to the sensitivity to delay time: One is SCO
(Synchronous Connection Oriented) link for voice or audio which is sensitive to delay time. The
other is ACL (Asynchronous ConnectionLess) link for packet data communication which is less
sensitive to delay time. Because SCO link can be established only after ACL link is established,
ACL link is also important to voice system.
This chapter describes the characteristics and usage of SCO link to use PCM input provided by
Parani-BCD110.
6.2. Characteristics
Parani-BCD110 supports single voice link at 8Khz. This voice link enables voice communication
to the degree of cellular phone, but is not suitable for music.
6.3. SCO Connection
SCO connection is available only when two devices are connected in single connection mode on
SPP and the property of ‘Enable SCO’ is enabled.
ATS84 = <Value><CR>
Enable SCO. If <value> is 0, SCO is disabled.
AT+SCOCONNECT<CR>
In case that SPP connection is established between two devices with ‘Enable SCO’ enabled,
AT+SCOCONNECT command establishes SCO connection and make Bluetooth voice
communication possible at the Development Board or PCM interface made like Appendix F.
AT+SCODISCONNECT<CR>
AT+SCODISCONNECT command closes SCO connection. Though SCO connection is closed, SPP
connection is still maintained. On the contrary, when SPP connection is closed, SCO connection
is also released.

this example, we will name a Parani-BCD110 master as Master and 7 Parani-BCD110s as Slave1,
Slave2, Slave3, Slave4, Slave5, Slave6, Slave7.
Step 1. Turn on Master, Slave1, Slave2, Slave3, Slave4, Slave5, Slave6, Slave7 and do factory
default by using RST signal.
Step 2. Set the pairing signal of Slave1, Slave2, Slave3, Slave4, Slave5, Slave6, Slave7 to low
state and hold the signal for 2 seconds to make them in Mode3.
Step 3. Turn them off.
Step 4. Set the pairing signal of Master to low state and hold the signal for 2 seconds.
Step 5. . Turn Slave1 on.
Step 6. Set the pairing signal of Master to low state and hold the signal for 2 seconds. Master
discovers and connect to Slave1, then Master is in Mode1 and Slave1 in Mode2. The BD address
of Slave1 is stored at S46 of Master.
Step 7. Turn Slave2 on.
Step 8. Set the pairing signal of Master to low state and hold the signal for 2 seconds. Master
discovers and connect to Slave2, then Master is in Mode1 / Multi-Drop Mode and Slave2 in
Mode2. The BD address of Slave2 is stored at S54 of Master.
Step 9. Turn Slave3 on.
Step 10. Set the pairing signal of Master to low state and hold the signal for 2 seconds. Master
discovers and connect to Slave3, then Master is in Mode1 / Multi-Drop Mode and Slave3 in
Mode2. The BD address of Slave3 is stored at S55 of Master.
Step 11. Turn Slave4 on.
Step 12. Set the pairing signal of Master to low state and hold the signal for 2 seconds. Master
discovers and connect to Slave4, then Master is in Mode1 / Multi-Drop Mode and Slave4 in
Mode2. The BD address of Slave4 is stored at S56 of Master.
Step 13. Turn Slave5 on.
Step 14. Set the pairing signal of Master to low state and hold the signal for 2 seconds. Master
discovers and connect to Slave5, then Master is in Mode1 / Multi-Drop Mode and Slave5 in
Mode2. The BD address of Slave5 is stored at S57 of Master.
Step 15. Turn Slave6 on.
Step 16. Set the pairing signal of Master to low state and hold the signal for 2 seconds. Master
discovers and connect to Slave6, then Master is in Mode1 / Multi-Drop Mode and Slave6 in
Mode2. The BD address of Slave6 is stored at S58 of Master.
Step 17. Turn Slave7 on.
Step 18. Set the pairing signal of Master to low state and hold the signal for 2 seconds. Master
discovers and connect to Slave7, then Master is in Mode1 / Multi-Drop Mode and Slave7 in
Mode2. The BD address of Slave6 is stored at S59 of Master. Once master connects to 7 slaves,
setting the pairing signal of master to low state is ignored and does not do anything.
Step 19. When any slave turns off and on, Master in Multi-Drop Mode automatically reconnects
to it.

A.1.5. Reset (RESETB) Signal
Parani-BCD110 can be reset from one of following sources:
 RESETB pin
 Power on reset
The RESETB pin is an active low signal and is internally filtered using the internal low frequency
clock oscillator. A reset will be performed between 1.5 and 4.0ms following RESETB being active.
So it is recommended that RESETB be applied for a period greater than 5ms.
A.1.6. PVCC Input
If PVCC input is not wired or input power is lower than 3.3V, working distance may be less than
that of the product specification which is 200m(0.12 mile) by defalut antenna and 1000m(0.62
mile) at maximum.

Purpose
Convert the operation status of ‘Connect’ to ‘Standby’
Description
In ‘Connect’ status, data from host is transmitted to the other side Bluetooth device,
and any AT command is not accepted except this command, which is not echoed on
the screen.
When Parani-BCD110 encounters a character ‘+’ from host, it stops the data
transmission and waits for next 2 characters. If the next 2 characters are not ‘+’, it
restart to transmit data including the first ‘+’ as well. If so, it converts the operation
status to ‘Standby’.
If the data from host includes ‘+++’, it will convert the operation status to ‘Standby’.
Notice that Parani-BCD110 holds data transmission when it encounters ‘+’, until
receiving next character.
‘+’ is an escape sequence character by default, which is changeable by AT+SETESC
and stored at S-register 28.

Appendix C: S-Register
S-registers contain the parameters for the Parani-BCD110. These are stored in flash memory and
the values will be saved unless hardware reset is executed. The value of S-register can be
accessed and changed with ATS command. Some S-registers not shown below are set to
maximize the performance of Parani-BCD110. Thus it is not recommended to change these Sregisters.
Change the value of S-register only in Standby status and turn Parani-BCD110 off and on.
C.1. S1: Force to Reconnect (default 1)
S1=0, Parani-BCD110 in Mode1 does not try to reconnect when disconnected.
S1=1, Parani-BCD110 in Mode1 keeps trying to reconnect when disconnected.
C.2. S3: Stream UART Policy (default 0)
S3=0, the priority of UART streaming is throughput.
S3=1, the priority is latency, which minimizes the delay of data transmission. This is useful in case
of transmitting very small data quickly.
When this value is 1, in order to minimize latency, Parani-BCD110 sends the received data
immediately. When this value is 0, the Parani-BCD110 maximizes throughput, the Parani-BCD110
stores received data for a short time and sends a large data packet. If the packet length is less
than 100 bytes, having latency being the priority is recommended. If the packet length is more
than 100 bytes, having throughput as the priority is recommended. Also, if you want to use high
baud rate, throughput priority will be more effective. Just for reference, the buffer length for
receiving data is 2 Kbytes.
C.3. S4: Enable Remote Name Query (default 1)
S4=0, Parani-BCD110 will query only the BD address. This speeds up the inquiry process.
S4=1, Parani-BCD110 will query the BD address, device name and class of device.
When this value is 1, Parani-BCD110 finds not only BD address but also friendly name. When this value is
0, Parani-BCD110 finds only BD address. When set to 0 this will make queries much faster. When using the
pairing button, finding friendly name will be omitted automatically.
C.4. S6: Enable Low Power Mode (default 0)
S6=0, deactivate Low Power Mode.
S6=1, activate Low Power Mode.
This value decides whether Parani-BCD110 works in Low Power Mode or not. When this value is
0, Parani-BCD110 works only in active power mode. When this value is 1, Parani-BCD110 will be

Appendix D: Trouble Shooting
D.1. No Data Transmission
D.1.1. Device Settings
Check whether the Baud rate of Parani-BCD110 matches that of its host equipment.
Check whether the host equipment of Parani-BCD110 uses Hardware Flow Control. ParaniBCD110 is initially set to Use of Hardware Flow Control. If your host equipment does not use
Hardware Flow Control, please disable the Hardware flow control option by ParaniWIN or AT
command.
D.2. Data Loss or Malfunctioning
D.2.1. Hardware Flow Control
When transmitting large amounts of data with No Hardware Flow Control, Parani-BCD110 may
clear the data buffer unexpectedly. The possibility becomes greater as the RF transmission
environment becomes worse.
D.2.2. Response Message
The messages of Parani-BCD110 response may affect the function of host system. Set ATS10=0 not to
send Parani-BCD110 response to host system and try again. Refer Appendix B. for details.
D.3. Transmission Delay
D.3.1. RF Processing Delay
It takes 30msec approximately for a Parani-BCD110 to complete a data transmission to the other
Bluetooth device. This time delay cannot be reduced and may enlarge as the RF transmission
environment becomes worse. Do not use Parani-BCD110. If your applications cannot allow for
this time delay.
D.3.2. RF Transmission Environment
If there are many Bluetooth devices working in a small area and/or the RF communication distance
is too great and/or there are some obstacles affecting RF performance, the Parani-BCD110
repeats the transmission packet by packet due to interferences and/or low RF performance. This
may lead to increased data transmission time delays.
