Hi,
I have a FMB920 and was doing some tests with my SIM forcing the GPRS connection to be down. I realize that every 6 minutes, device is kind of rebooting, or at least it's resetting the modem side and the communication with the SIM card.
Are those 6 minutes configurable or even removable?
On top of that, I also feel that Refresh command sent by my SIM to the device aren't forcing the module to be rebooted, I have to wait till those 6 minutes to be elapsed to notice that modem is asking the SIM for all the needed parameters again.
Thanks in advance!
