#90067 I was checking the ESP12-E module with the help of AT commands, but the ESP12-E module stopped working unexpectedly. When I reset it, it responds as "ready" but not responding to AT commands. When I try to update it, it gives an error "chip sync is closed". The blue light of the module turns on when you press the reset button. I tried 115200 and 9600 baud rate.please help me.thank you vcc=3.3v gnd=gnd ch-pd=3.3v reset=gnd gpıo0=gnd rx=tx tx=rx
