6  Service and firmware update 
The Telit GE863 modules 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 module’s firmware, to foreseen  an external access to that interface with level converters 
to RS232, which allows connecting a Windows-based PC, since it is normally not possible to 
disconnect a GE863 module already soldered on the PCB of the application. 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 GE863 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. 
 
First the program will erase the content of flash memory, then the program will write on the flash 
memory. To update the firmware of the module, we suggest the following procedure:  
1.  Collect information about the Hardware and implemented version of Software by the 
command  
- AT+CGMR<enter>, which returns the Software version information; 
- AT+CGMM<enter>, which returns the Model Identification.  
 
2.  Switch OFF the module.  
 
 
3.  Run the file TFI_xxxx.exe. The following window should be displayed, Select the language 
preferred by pressing the correspondent button. 
 
 
 
4.  The End User License Agreement will appear. Please, read it and accept the terms if you are 
going to proceed.
