EdgeTX Passthrough for ELRS Upgrade

With EdgeTX operating system, flashing ExpressLRS internal TX modules is easier for everyone. First, there is no need to disassemble the case. Compared with upgrading by WIFI, it is more convenient, fast, and stable to flash ELRS internal TX firmware by using EdgeTX passthrough flashing.

Note: Please click here to know the upgrading steps. The passthrough is only used for ELRS 2.4G version. Currently, BETAFPV is actively communicating with the ExpressLRS official team on the latest ExpressLRS configurator to support flashing LiteRadio 3 Pro ELRS TX firmware.
