Trying to get some response out of my ESP8622 via my Arduino UNO. All was going OK, until I attempted to change the BAUD Rate by using the command "AT+UART_DEF=9600,8,1,0,3", now I only get gibberish when I power up the ESP8622, and zero response to "AT".
I appreciate that using _DEF wasn't the best idea, but it's done now. Also understand that the 3 at the end probably should have been a 0.
I can get some sense in the Serial Monitor at 74880, but still no response to anything sent.
I've even toyed with flashing the ESP8622, but can't get a connection at any BAUD rate.
Anyone have any suggestions?
