- Sun Feb 07, 2016 10:12 pm #40657 i have accidentally change the baud rate of esp8266 to unknown number, what shall i do?

Are you using Arduino ESP or AT firmware ?

In Arduino sketch, it is up to you to define Serial.begin(<baudrate>); in your setup() loop.

If you are using AT firmware, your question should be "how to get rid of AT firmware"

i after i have connected to my esp8266 through my arduino uno and used the serial monitor, and changed by accident to an unknown number using AT+CIOBAUD=115200

You probably need to erase the configs stored at specific location.
On most ESP, this command will do :

Code: Select allesptool.py --port /dev/ttyUSB0 write_flash 0x0007e000 blank.bin
