  • I'm not able to connect to Wifi either, similar issue as others have had with the uncaught no ready.
    I can send AT commands, I have the red light, I get the blue light when sending a command

    I have the 0.25 version ESP8266 (AT+GMR) am loading the right module and baud is set to 115200. I have a 10uF capacitor between ground and +3.3v at the connections on the ESP8266.

    I've logged the ouput of AT+RST below, I've no idea what I'm looking at but it seems to suggest a memory issue MEM CHECK FAIL.

    Can anyone help me move forwards?
