5.11 Turning OFF the modem
The modem contains the EGM standard library (see the documents
"ublox_AT_Commands_Manual_xxx.pdf"); in this case, it is strongly advised to un-register from the network
with the command AT+COPS=2.
If the Battery option is present, a mechanism allows to stop compeletely the application if the
external power supply is unplugged, and also to prepare the modem for storage or transport
phases in order to limit high discharges of the battery.
If the device is not used, it has to be deactivated by sending the following command:
• If the modem contains an application developed with EGM
Switch off the external power supply of the modem
Wait 20s
Send the command AT+GPIOSET=35,0
• If the modem does not contain any embedded application via the Boot-Loader menu
Bootloader V4.11 GP25 UA Gener Ublox (HWF7 rev C)

supply.
5.12 Updating procedure of the modem
To be able to benefit from the latest functions of the GenPro 25e, an updating procedure can be used to
upgrade the software program in the modem.
This procedure consists in downloading the software into the internal Flash memory of the modem via the
RS232 link available on the 15-pin Sub HD connector.
Contact us for the software updating.
