7 thoughts on “GE865 GPRS Disable Auto Attach to save battery ?”
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
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.
You’re right, no difference in current consumption in Attach or Detach…
Thank’s
Thank you too Bruno for the check.
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.
