I have been trying to have the ESP8266 connect to my laptop that is running an ad hoc access point. The access point shows up when I send the "AT+CWLAP" command to the ESP8266, but it never seems able to connect using "CWJAP="<ssid>","<pswd>". I keep getting the response "+CWJAP:3" followed by the message "FAIL" on the next line.
Note that other devices can connect to the ad hoc network, so the SSID and PSWD and ad hoc network set up don't seem to be the problem.
Any suggestions?
