There is a bug in the latest FrSky firmware v1.0.10 for the “Archer Plus Rxx” receiver series (R6, R10, etc.), which does not allow the use of integrations and other LUA apps using the F.Bus protocol.
This bug has been known to FrSky since February 2024 and which FrSky has so far failed to resolve despite numerous reports from users.
To “get around” the bug, the F.Port protocol can be used but without being able to use additional sensors that do not work with this protocol.
If, on the other hand, you want to be able to use the F.Bus protocol without any problem, which unlike the F.Port protocol allows additional ADV sensors to be connected to the bus (EG: GPS, Variometer, FrID, etc. etc.), you must downgrade the FrSky receiver firmware to the penultimate firmware available on the FrSky site.
