My SMB5100 stops sending Serial Data to the NSS port after about 30 minutes.
I have my module:
Connect to the network (happens automatically when arduino starts)
wait
Check for new messages
wait
If New message, go to last message
wait
Get the phone number from the last message
wait
Txt the phone number
wait
Send reset command to Cell chip
wait
Connect to network and start the whole thing over again.
After about 20 iterations, i stop receiving anything in my serial port from the SM5100.
Has anyone run into this problem? Any thoughts?
