Hi,
Currently I'm working on a system that sends data by GPRS.
The system crashes if someone texts/dials the number of the SIM-card inserted.
I looked in the AT-command manual and couldn't find a way to block incoming calls/sms.
Is there a way?
EDIT: I found AT+GSMBUSY = 1 which blocks all incoming calls.
I hope it doesnt wake the SIM800 from sleepmode.
