Downloading EdgeTX Companion

EdgeTX Companion 2.9 is (pick the appropriate download for your operating system from Assets heading at the bottom of the page - the filename will have cpn in the name).

Enabling support for Mixer Scripts

If you intend to use mixer scripts, when compiling the firmware for your transmitter you need to make sure the LUA_MIXER option is set. This is not required if you only intend to run any of the other types of Lua script (i.e. telemetry, one-time, function scripts, widgets) as support for those is included by default.
