Firmware Update
The firmware of the
µ
controller can be loaded locally (via the serial
interface), and remote (CSD or "TCP transparent" connection).
Before the firmware is updated, hardware handshake must
always be activated ((INSYS GPRS 5.1 serial and remote ter-
minal).
The process is started. The device prepares itself for receiving the
new firmware.
After the response, the firmware (file with the ending *.hex) is sent
as a text file.
After the file has been received, the device needs up to 60 seconds
to complete the upload. Afterwards, the (INSYS GPRS 5.1 serial will
automatically perform a restart.)
Note
After an update, the settings are reset to the factory defaults.
The SIM card PIN (AT**PIN) and the standard command settings of
the GSM/GPRS engine are maintained, which means that if auto-
matic call acceptance (e.g. ATS0=2) is activated, the device can still
be accessed from outside to enable the re-configuration of the ex-
tended functions per CSD call via remote configuration.
