How to change ESP8266 Baud-rate permanently

[Derby43]

Ok so this something new for me, I am using one of the most light weight IOT device called Feather Huzzah connected with I2C feather shield and I wanted to ESP2866 to communicate at baud-rate 115,200 but I didn't find out the way how should I change the baud-rate permanently ?

Any intel would be appreciated

Thank you

You can't. It's configured in ROM.

If its configured at Baud-rate of 9600 and If I wanted to change the baud-rate to 115200 then what should we do ?

Calling Serial.begin(115200) in setup() will set the baudrate before any of your other code executes. You just can't rewrite the hardware boot-up configuration settings.
