Hello,

I am experiencing some problems with the AT commands. When I pass eg. the command AT+RST to the esp8266, I receive the following response :

AT

busy p/..

OK

Command AT+RST gives this response :

b]®^‚¹rr

OK
WIFI FIS¨ÊÊªQ5

So some of the text is ok, but strange characters appear. As some of the text can be read, I suppose this has nothing to do with the baudrate ? I am using an external power supply, and comminucate through softserial. I tried with several esp8266 modules, but all produce the same response. Does anyone know what is causing this problem ?

I had / have the same problem. I made my wiring more secure and had the power come straight from my arduino. This made the results more reliable but still not perfect. My thinking is to slow down the baud rate by changing the firmware giving both boards time to talk to each other.
I don't know if this helps
