#92562 So I was using an arduino nano to control my esp8266 via at commands. But the esp8266 isn't responding to the AT commands. I checked different baud rates. Used my pc with cp2102. Flashed the v1.7.4 nonOS at firmware. However it is outputting some lines when ch_pd is pulled to ground. And it says 'timed out waiting for packet header' when uploading any sketches.
