My ESP8266 has stopped working. The red power light comes on and the blue TX light is on solid.
Here's what I did.
Connecting
ESP8266 -> Arduino nano
VCC
, CH_PD
, RST
-> 5V
(external supply)
TX
-> TX
RX
-> RX
I could send AT commands via the serial monitor.
Then I connected
RX
-> 11
TX
-> 10
and set up software serial intending to repeat the experiment.
I was getting garbage characters in the response, and found that I had to esp8266.println("AT+IPR=9600");
to reduce the baud rate.
Then the blue TX light cam on permanently and it's stopped working at all.
