ESP8266 Community Forum

- Mon Jun 15, 2015 6:56 pm #20537 My ESP8266 came in the mail today (wasn't expecting it till the end of the month.) I have found that I can set the baud rate to 9600 but upon a power cycle it resets to 115200. Don't know if it's a bug that's been fixed in a later firmware version, although it appears to be a recent firmware version. I read someone had the same issue a few months ago.

Code: Select allAT+GMR

OK


- Tue Jun 16, 2015 4:19 pm #20629 have a read in the wiki. The firmware on the chip sets it and it starts at 74880 then shifts to 115200 but you can override that behaviour but you will have to research it.

AT+CIOBAUD=9600 is not persistent when the ESP8266 is reset.
AT+IPR=9600 kills the ESP8266 and you will have to reflash the firmware to get it working again.
AT+UART=9600,8,1,0,0 will set the baud speed to 9600 and it is persistent after a rest.

What's that supposed to mean Chum?
