6 Service and firmware update
The Telit GM862-GPS module firmware can be updated through the same serial interface, which is used
normally for the AT commands. Since the software group is continuously working, in order to improve
the overall performances and introduce new features on the product, we suggest, in order to keep
updated the modules firmware, to foresee an external access to that interface with level converters to
RS232, which allows connecting a Windows-based PC. It shall be possible to start the update
procedure at POWER OFF condition of the module and then switch it ON to continue.
During the application development or evaluation phase of the
Telit GM862-GPS module, the RS232
interface with the level converters or the USB port implemented on the Telit Evaluation Kit EVK2 can
be used to connect to a Windows-based PC on which the specific program for updating the Software
(TFI) can be run.
6.1 Step-by-Step upgrade procedure
The firmware update can be done with a specific software tool provided by Telit that runs on Windows
based PCs.
