I don't know really where to look, so if anyone can help me, i'd appreciate it. I'm working with an ESP module connected to an arduino nano. I used this sketch (https://github.com/bonggeek/Samples/blob/master/Arduino/SerialRepeater.ino). The module turns on an the communication seems to work. However, any command I type in, even just AT, gives me an ERROR response. Oddly the AT+CIOBAUD works just fine and gives me OK. Does anyone know what it might be?
