3.4 Recovering the GT Lite 

 
There is a small chance that main processor programming can fail in such a way that the 

device becomes unusable until recovered.   

1.  Download and install DWLWin from the Sierra Wireless if it is not already done. 

2.  Put your board in bootloader mode by jumpering J5 (shown above in Figure XXXXX) and 

putting J29 in Programming mode as shown in Figure XXXXXXX above. 

3.  Connect the GT Lite debug cable to the external Conxall connector.  Connect the serial 

(RS232) end of the debug cable to a PC. 

4.  Power GT Lite on. 

5.   Open DWLWin and set it to the correct COM port and 115,200 baud.   

6.  Uncheck all files under Working Dir. 

7.  Check “Open AT Application”  and “Objects” under Erase. 

8.  Select “Wireless CPU Type as Q2686/Q2687. 

9.  Click Start in DWLWin, and then hold down switch S1 (shown in Figure XXXX) on the 

board until the whole process is done.
