xE910 with GPS, possible to power down GSM part while accessing GPS

1. Hi,

    

   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.

    

   Thanks

   1. 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.

         1. In CFUN=5 the module is sleeping, not responding to the user application, so no use for your case.
