ESP32 Forum

I have a Heltec Wifi Lora 32 and try to change the baud rate of the serial console.
By default the ESP is sending on 115200 so if I run it's able to read the output from the ESP.

Now i want to flash the hello word example. For this I run: And just set the serial port and save it (monitor baud rate is still at 115200!).

Then I run: And now the monitor outputs just jibberish. If I now set the monitor baud rate to "custom baud rate" with 74880 as baud rate, I'm able to read the output again.
Is there a way I can set the sending baud rate of the ESP back to 115200?

My guess would be that your board has a 26MHz crystal in it; esp-idf by default is configured for a 40MHz crystal. You can change this in menuconfig (components -> esp32-specific options, if memory serves.)

Works thanks!

And just for those who come here with the same problem, the exact path to the option is:
"Component config" ---> "ESP32-specific" ---> "Main XTAL frequency (40 MHz)"
