Proper shutdown sequence


#1

Is there a proper way to turn off the Fastrack Supreme?

Just unplug and go?

For a clean shoutdown, you should do AT+CFUN=0 (and wait for OK) before pulling the power.
This ensures that the unit has cleanly detached from the network.
Also that it’s not in the middle of updating the SIM, etc.

That wouldn’t actually hurt anything!
