F4 V3s Plus does not have IBUS port. Tried ti use, as advised a free UART. Inmy case RX 6 and set:
I did set the receiver to IBUS as well as on my FS-i6 RC.
That did not solve the problem.
I tried another approach.
Connecting the data wire to PPS as in the manufacture's instructions.
Changed the setting in Betaflight and the FS-i6 to PPM
OFF and ON
Stll the FC does not communicate with the receiver.
Any ideas? this is very frustrating.
