10. GL61x0 Maintenance
10.1. Enabling/Disabling the Flash LED
The GL61x0 has a red LED indicator that shows the status of the GSM network. It is possible to
disable this LED during Sleep mode in order to reduce power consumption. Using a communication
software such as HyperTerminal, enter:
AT+WHCNF=1,0 to deactivate Flash LED
AT+WHCNF=1,1 to activate Flash LED
Note: The GL61x0 will need to be restarted for the new settings to take effect. Refer to document [7]
Firmware 7.42 AT Commands Manual (Sierra Wireless Software Suite 2.32) for more information
about enabling/disabling Flash LED.
10.2. Resetting the GL61x0
Resetting the GL61x0 could be triggered by the AT command AT+CFUN=1, or:
For GL6100 RS232, it could be done by unplugging and then re-plugging the power supply
(Vin).
For GL6110 USB, disconnect the Modem from the PC USB port.
Caution: While the GL6110 is being reset by AT command, the PC communication software might have to
close the USB port and then re-open it to resume communications.
10.3. Operating System Upgrade Procedure
The GL61x0 operating system is stored in flash memory and can be easily upgraded.
The operating system file can be downloaded into the modem using the X-modem protocol. The
AT+WDWL command allows the download process to be launched.
