1. Hello,

    

   Is it better to disable auto attach and detach GPRS issuing AT+CGATT=0 everytime gprs connection is not being used  to save battery on GE865 ? Or it doesn’t make any difference ?

    

   Thank’s

   1. I don’t think will matter, as long as you don’t have a connection open.

   Ok Thank’s.

    

   Yes, no connection opened, i’m concerned just about the attached status.

    

   Please, don’t close the thread yet, i’ll measure current consumption with both attach and detach and post the results here later.

   1. You’re right, no difference in current consumption in Attach or Detach…

       

      Thank’s

      1. Thank you too Bruno for the check.

         1. Here is one more remark from my colleagues, affecting only really long running applications:

             

            I f the module is
            GPRS registered periodically has to execute PERIODIC ROUTING AREA UPDATE
            (message exchanging with the NET). Update period is usually 1 or 2 hours in
            the live network (it depends by the MNO configuration) so for sure if the
            application has been designed to sends SMS only for 5 years this GPRS
            procedure can have a little impact on battery duration.

            1. Interesting, thank’s
