Install/Update Firmware
:::caution Be very careful to install the correct load for your board. In particular the popular 'T-BEAM' radio from TTGO is not called 'TTGO-Lora' (that is a different board). So don't install the 'TTGO-Lora' build on a TBEAM, it won't work correctly. :::
Install Firmware
Install the correct firmware for your board using the following command. Be sure to select the correct board and frequency.
./device-install.sh -f firmware-BOARD-VERSION.bin
./device-install.sh -f firmware-heltec-EU865-1.2.0.bin
Update Firmware
To update a the firmware on an existing Meshtastic device use the following command. Be sure to select the correct board and frequency.
./device-update.sh -f firmware-BOARD-VERSION.bin
