I've just received my MOD-WIFI-ESP8266-DEV boards and plug it on my breadboard.
connected pins are, GND, 3.3, and RX/TX. the MOD-WIFI-ESP8266-DEV is in default flash mode.
when i connect to it at 115200 i have a welcome "ready" than when passing AT i receive OK.
But any other command like AT+CMGR or AT+CWLAP are returning ERROR.
any setup i missed...
Try other AT commands.
You may need both CR and LF.
the module comes by default in mode 3 (ie AP) , so AT+CWLAP wich is a scanning command is not available
i switched to mode 1 by AT+CWMODE=1 and everything is working fine
If only all the posts were so quickly resolved :)
Good to hear!
