I connect wizfi to putty and I can send AT commands such as “at” “at+uset” the MODE LED is off on the module.
I canot send “at+sdata” in order to return to data mode I receive “error mode status” which If I understand right means that I already am in data mode?
If so how do I go to command mode?
pasted from the guide
How do I send the ‘+++’ ? With putty? with MCU? and what would be the format? As string value? ascii?
