Part IV - Converting OpenTX 2.0 Scripts

The handling of telemetry data is significantly improved in OpenTX 2.1. However, in order to support the additional flexibility of having multiple sensors of the same type, many Lua scripts referencing GPS and Lipo sensor data will require revision.

This section also covers some of the requirements for scripts that are necessary for them to function properly under both OpenTX 2.1 and OpenTX 2.0.
