By default, the ELRS-2.5W-TX high-frequency head only accepts signals from the Crossfire Serial Data Protocol (CRSF). The high-frequency head interface of the remote control needs to support CRSF signal output. The following takes the OpenTX remote control system as an example to illustrate how to configure the remote control to output CRSF signals and use the LUA script to control the ELRS high-frequency head.
