Introduction
The tBLE-720 module is designed for serial network like RS-232, RS-422 or RS-485. It allow
RS-232, RS-422 or RS-485 interface to be converted to Bluetooth low energy (LE) piconet
network. User can choose tBLE-720 or mobile device (e.g. smart phone, tablet or notebook) to
do the connection, which provides Bluetooth LE data conversion between two devices. The
tBLE-720 has two transmission modes – advertisement and connection mode. User can use AT
command or dip switch to change transmission mode. The tBLE-720 supports a lot of useful
AT commands. They can set many parameters such as connection parameters, broadcast
parameters and Bluetooth LE role.

1.3 Transmission Mode
The transmission mode of tBLE-720 can divide into two categories: Broadcast and connection.
Each mode had different roles. The Broadcaster/Observer (scanner) was used in the broadcast
mode. The Master/Slave was used in the connection mode.
tBLE-720, RS-232/RS-422/RS-485 to Bluetooth Low Energy Converter (Ver. 1.0, Oct/6/2016) 6
1.3.1 Broadcast Mode
The broadcast mode is the new features in the Bluetooth LE. The Bluetooth LE
Broadcaster device broadcasts packets to every device around it. The Bluetooth LE
Observer device can receive the information without connection. The tBLE-720 supports
another feature in broadcaster mode. The Broadcaster and Observer (refer to 1.5.2) had an
identification ID, and it call “Group ID”. The “Group ID” (refer to 3.1.15) parameter
specifies the logical group identity for tBLE-720 devices, and each tBLE-720 module
must be set to the same value if it is in the same group as other modules.
The schematic diagram of broadcast mode was shown in Figure 1-2. It had two
broadcasters and ten observers. The Observer 1~5 can receive packet from broadcaster A.
The Observer 6~10 can receive packet from broadcaster B. The Observer 1~5 can receive
the information without connection. The Observer 1 also can receive packet from
broadcaster B, but the Observer 1 only can receive packet from broadcaster A because the
Group ID is different.

1.3.2 Connection Mode
The connection mode need make a connection before packet exchange. The slave will
broadcast after power on. If the master receive broadcast packet from the Slave and it will
send connection request to the Slave. The Slave can connect to one Master unless it
disconnect with current Master. The Master can connect with three Slaves. If the number
of slave connections was reached to 3. The Master will not send connection request unless
the connections was less than 3. The Slave and Master also had “Group ID” (refer to
3.1.15). The Slave and Master must be set to same “Group ID”, and the Master will send
connection request to the Slave. The Slave had a master identification mechanism. The
Slave receive connection request from Master. If the illegal Master was connected to the
tBLE-720, RS-232/RS-422/RS-485 to Bluetooth Low Energy Converter (Ver. 1.0, Oct/6/2016) 7
Slave, and then the Slave will be disconnect from Master. The master identification
mechanism can disable by AT command.
The schematic diagram of broadcast mode was shown in Figure 1-3. It had two Masters
and six Slaves. The Master A will connect to the Slave 1~3, and the Master B will connect
to the Slave 4~6. The Slave 1 is in the commutation range of Master B, but the Master will
not send the connection request to the Slave 1 because the Group ID is different.

1.4 Operation Mode
The module will in the initialization mode after power on. If the initialization was success, and
the module will went to the transmission mode. The module can send data or it can receive the
data in the transmission mode. User sends the “+++<CR>” to the module. It will be entered to
the AT command mode. The module will in the AT command mode until 50 second without
any commands or send the “ATE<CR>”. The AT command mode can refer to 3.13.1.

1.5 Bluetooth LE Role
The Bluetooth Low Energy (LE) had four roles. The roles are Master (Central), Slave
(Peripheral), Broadcaster and Observer. The Master and slave had used in the connection mode.
The Broadcaster and Observer has used in the broadcast mode.

1.5.1 Master and Slave
First, there is the concept of Master (Central)/ Slave (Peripheral), which has to do with
establishing a link. This is also known as the GAP role. A Peripheral can advertise, to let other
devices know that it's there, but it's only a Central that can send a connection request to
establish a connection. When a link has been established, the Central is also called a Master,
while the Peripheral could be called a Slave. The Slave only can connect to a Master, but the
Master can connect to three Slaves. The Slave will not sending broadcast packet after link has
been established.

Figure 1-5. The workflow of Bluetooth LE connection
The Slave has two broadcast patterns. One is the high discoverable mode. The other is low
discoverable mode. The Slave will be broadcasting for 30 second in high discoverable mode,
and the broadcast interval is 20ms for 3 channels. The Slave will be broadcasting for 60 second
in low discoverable mode, and the broadcast interval is 640ms for 3 channels. The Slave will in
the high discoverable mode after power on. If the Slave didn’t received connection request from
the Master in high discoverable mode and it will switch to low discoverable mode. If the Slave
didn’t received connection request from the Master in low discoverable mode for 5 times (300
second) and it will switch back to high discoverable mode.
1.5.2 Broadcaster and Observer
The Broadcaster does so by constantly advertising, and the Broadcaster usually has useful data
tBLE-720, RS-232/RS-422/RS-485 to Bluetooth Low Energy Converter (Ver. 1.0, Oct/6/2016) 9
in the advertising packet. The advertising packet is meant for everyone to see. The Broadcaster
is broadcasting to others, so it never accepts connections. The Observer is the opposite of the
Broadcaster: it passively listens to BLE devices in its area and processes the data from the
advertising packets it receives.

1.6 Master Identification Mechanism
The Slave had a master identification mechanism. The Master will send identification packet to
the Slave. The Slave will check the identification packet that the identification packet was
incorrect. The Slave will disconnect with the Master. The feature can enable by AT command
(refer to 3.1.19).

Software
3.1 The AT Command
3.1.1 The AT Command syntax
The AT commands help users to control or get the information of tBLE-720. The prefix “AT+”
must be included at the beginning of each command line (except +++, AT and ATE), and
the character <CR> is used to finish a command line. When the application would like to send a
series of AT commands, leave a pause between the preceding and the following command until
information responses (e.g. “OK”). In the present document, AT commands can divide into
four types: Write Command, Read Command, Test Command and Execution Command. If the
AT command isn’t exist or syntax error, and the tBLE-720 would be reply error code. All of
AT commands will valid when the module was entering to the AT command mode (except
+++). The correct flow of AT command was shown in Figure 3-1.

without any command after
50 second
Figure 3-1. The flow of AT command
1. Write Command
The write command can write configure to the tBLE-720. The format of write command is
“AT+XXX=YYY<CR>”.The “AT+” is a beginning in the command, and the “XXX” is
command name, and the “YYY” is a parameter, and the<CR> is end of the command. The
syntax or parameter was incorrect and the tBLE-720 would be reply error code. The user didn’t
reset configure again because all of configure will be save in the local memory after receive
write command.
2. Read Command
The read command can read configure from the tBLE-720. The format of read command is
“AT+XXX?<CR>”.The “AT+” is a beginning in the command, and the “XXX” is command
tBLE-720, RS-232/RS-422/RS-485 to Bluetooth Low Energy Converter (Ver. 1.0, Oct/6/2016) 18
name, and the “?” is read command, and the<CR> is end of the command.
3. Test Command
The test command can examine the syntax of command and give the information about the
command parameter. The format of test command is “AT+XXX=?<CR>”.The “AT+” is a
beginning in the command, and the “XXX” is command name, and the “=?” is test command,
and the<CR> is end of the command. All of AT commands supports the test command. If the
syntax of command is correct. The tBLE-720 would be reply “OK<CR><LF>”.
4. Execution Command
The execution command can execute some functions (e.g. reset the module). The format of test
command is “AT+XXX<CR>”.The “AT+” is a beginning in the command, and the “XXX” is
command name, and the<CR> is end of the command.
