2 General Hardware and Software Limitations
•
Noise Reduction and Echo Cancellation are working only at low quality level. Basic
Handsfree operation (Speakerphone) is not yet supported. The Ringing Tone generator
does not always work reliably.
•
The feature RTC wake-up from POWER DOWN mode is not available. Programming an
alarm time (AT+CALA) will not wake up the module automatically. Despite this, AT+CALA
can be used any time during normal operation.
•
Autobauding does not work reliably. It is recommended to set a fixed bit rate. By default,
when shipped from factory or after a firmware update, the modules are set to
115200 bps.
3 Hardware Limitations Specific to the TC65 Terminal
This section applies only to the TC65 Terminal.
After switching the TC65 Terminal off by using the EMERGOFF signal wait at least 1 second
(from the deactivation of EMERGOFF) before restarting the TC65 Terminal. During this
1 second period, invalid states may occur on the GPIO connector and on the serial interface.
4 Software Limitations
•
When changing from data to command mode, the TC65 fails to indicate the correct
response and, instead, returns a response related to the last event. The error occurs with
CSD connections, connections set up by using the Internet Service AT commands of
TC65 and the operation of I2C and SPI.
For example, after the remote party has closed the CSD connection, the TC65 returns
the response “CONNECT 9600/RLP” instead of “NO CARRIER”.
•
The maximum number of concurrent IP sockets is 8, due to memory limitations. This
includes all socket connections, no matter whether established from the Java application
or by using the Internet Service AT commands of TC65.
Please consider that the Java classes SocketConnection, Http(s)Connection,
SecureConnection and UDPDatagramConnection use up one socket each. The amount
of sockets for each ServerSocketConnection is two sockets for queued connection
requests and one socket reserved to accept the next connection. Each further accepted
connection occupies one socket.
•
The Socket Listener may not work properly if the service is re-opened shortly after having
closed the Socket Listener. To ensure that the service works correctly the host is
required to wait at least two minutes before re-opening a Listener.
•
The handling of the Master Phone Code (PH-SIM PUK) currently differs from the
description provided in [1]. This release of TC65 requires both the Master Phone Code
and the new “PS” password be given at the same time. So, at present, the TC65 will
TC65_rn_v01.041

TC65 Release Notes

accept only the command AT+CPIN=<MasterPhoneCode>, <newPassword> which sets
the “PS” lock once again. To remove the “PS” lock use the command AT+CLCK as
described in [1].
The commands AT+CPIN=<MasterPhoneCode> and ATD*#0003*MasterPhoneCode#
will be supported again in later TC65 releases.
•
The string parameters of the AT^SJNET read and write command (<bearer service>,
<entry point>, <login>, <password> and <dns>) are currently coded in ASCII character
set only.
In later releases of TC65 the settings of AT+CSCS will apply as specified in [1].
•
DNS configuration: In some networks, automatic DNS assignment may cause the TC65
module to shut down unintentionally when the subscriber attempts to set up a network
connection. The problem may occur if the network has no valid DNS server, but in rare
cases it has been observed even though both the module and the network are configured
for automatic DNS assignment. Setting manual DNS server addresses in the network
resolves the problem.
Also, note that even if a network has no automatic DNS service at all, it is necessary to
set a DNS address unequal 0.0.0.0. This means for example, when you create an
Internet profile with AT^SICS bear in mind that the “dns1” parameter must be set.
Otherwise, if not set, the default value 0.0.0.0 would be assumed which does not work in
a network without automatic DNS service.
The problems are related only to features based on the embedded TCP/IP stack of TC65,
such as the Internet Service commands and the Java application used with TC65.
Connections set up over the Dial-up network do not use the embedded TCP/IP stack and
are not affected.
•
Before setting AT^SCFG="MEopMode/Airplane/OnStart",off" or AT^SCFG="MEopMode/
Airplane/OnStart",on"
please
enter
the
read
command
"AT^SCFG=
"MEopMode/Airplane/OnStart".
•
Charge-only mode and overtemperature conditions: If the upper temperature limit is
exceeded while the charger is plugged the module shuts down and restarts into Chargeonly mode as specified in [2].
Then, the following error occurs: After cooling down the module and trying to switch from
Charge-only mode to Normal mode or Airplane mode, the module shortly starts up and
switches off again although the temperature is back to normal.
To avoid this problem, disconnect the charger and wait for the “^SHUTDOWN” URC.
Then the module can be started again without any problems, for example by using the
IGT line or connecting the charger.
•
If you wish to use the WinMux driver supplied by Siemens for implementing Multiplex
applications under Windows 2000 or Windows XP take care to use the latest driver.
Particularly if you want to operate the USB interface in Multiplex mode, do not use any
WinMux drivers delivered with earlier Siemens GSM module types. The latest version
delivered with TC65 is 2.2.0.0. To check the version number under Windows right-click
the winmux2k.sys file and select the Version tab.
If the WinMux driver is used on the USB interface, it is not recommended to send the
AT^SMSO command while Multiplex mode is active. To quit Multiplex mode and switch
off the module, first close the Multiplex channels, then open the host application without
Multiplex mode and finally enter AT^SMSO. Remember that the host application running
on the USB interface must be closed before restarting the USB interface as described
in [2].

•
If the USB interface is used to update the TC65 firmware, problems may be encountered
due to the latencies of USB device detection, for example if the USB host is slow
(Clock<1GHz) or the operating system supports only old USB drivers (Windows 2000). In
extreme cases the firmware download may be aborted. As a workaround, you can try to
restart the update procedure any time. The best approach, however, is using an
appropriate USB host, e.g. a PC running Windows XP and fast enough. For further
information on how to update the firmware see the AT^SFDL command in [1] and the
chapter “Generic Firmware Update” in [6].
•
While reading data from the InputStream of a Stream/SocketConnection, the Java
function available() could return 2048 bytes instead of the current available bytes. In this
case, the data are available, but the number cannot be resolved and may be any number
between 2 and 2048.
•
Note for customers migrating from TC45 to TC65:
If you uninstall the TC45 software after the installation of TC65 you need to run the TC65
SDK and MES setup in maintenance mode to restore several files required for TC65. To
do so, open the Windows Control Panel, double-click Add or Remove Programs, select
“TC65 Software Development Kit”, press the Change/Remove button and select Repair.
In the same manner, reinstall the "Siemens Module Exchange Suite (MES)".
As an alternative, to avoid this step, remove the TC45 package, before installing TC65
SDK and MES.
5 Recommendations for GPRS
AT^SGCONF: The factory default of the PDU length parameters is 500 octets. In some
networks, however, it may be advisable to select the maximum value 1520 in order to
increase the performance. The setting is stored non-volatile.
6 Handling of TC65 Modules Prepared for Customer IMEI
This section applies only to TC65 modules delivered with the IMEI and software version
number (SVN) left blank. This is a product line which allows application manufacturers to
store their own IMEIs and software version numbers.
Mobile equipment is not admitted to the GSM network unless the IMEI is assigned and
stored inside the device. Therefore all TC65 modules with blank IMEIs are preconfigured
only for use in Airplane mode, meaning that the TC65 enters the Airplane mode when
switched on. The mode is indicated by the URC “SYSSTART AIRPLANE MODE”.
In Airplane mode, all AT commands requiring a radio connection are deactivated, including
the option to enable/disable the Airplane mode with AT^SCFG. Only network-independent
features are usable and available to run basic tests in the factory. The AT commands
required for writing the IMEI and the SVN are also permitted. After successfully writing the
IMEI and the SVN the TC65 module needs to be restarted. The module will then enter the
Normal mode, indicated by the URC “SYSSTART”.
