in our battery driven application we are planning to use a xE910 module with integrated GPS receiver.
Powering down the GPS receiver seems to be possible through AT command interface (AT$GPSP=0). I’m wondering, if it is also possible to turn off the GSM part while retaining GPS functionality?
Application is to query GPS more often that doing data transfer via GSM/GPRS.
The option would be AT+CFUN=4 although not much decrease in power consumption.
Thanks for the reply. That means, that AT+CFUN=5 does not work? To be honest, it is not completely clear to me, how AT+CFUN=5 impacts module operation.Hardy
In CFUN=5 the module is sleeping, not responding to the user application, so no use for your case.
