To select the correct tty port, use the command `make menuconfig`, then navigate to **Serial Flasher Config -> Default Serial Port** and choose the correct port. ## Sensor Issues If the sensor output is around **80°C**, there is likely a power connection issue. If the output is around **-127°C**, the sensor's data wire is probably not connected. ## Compilation Errors If the temperature input is `none`, it might be due to a compilation error caused by an incorrect SDK configuration. Use the command `make menuconfig` and change the following settings: **Component config -> newlib -> Disable nano formatting**
