Hello - I'm after some help to get a XR02T-D receiver to show stick movement in BF. I'm connecting it to a IFLIGHT SUCCEX-E Mini F7 V1.4 and it is replacing a Spektrum micro receiver that didn't have telemetry (everything worked fine before removing it). The instructions that came with the XR show a wiring installation that is practically the same as the Spektrum although there are a few settings in BF to change. Hopefully both images show. Installation almost appears the same as a Frsky R9 mini?

XR is bound and I'm receiving telemetry at the Tx however nothing seems to be registering at the FC. As per the instructions I've left the Serial Rx as ON in ports tab UART2 (this was the UART of the Spektrum Rx), made sure that SPEKSAT was still selected, changed Rx provider to FPORT but I cant get the Telemetry slider to stay activated. I've added CLI settings "set serial halfduplex = ON" & "set serialrx inverted = OFF".

Another thread talked about how to measure whether the RX is actually sending a signal to the FC and it was suggested that a small % of the input voltage would show. There is continuity from the solder connection on the RX board to the end of the signal wire. I tested voltage on a standard 6 channel Spek receiver and got 0.46v at a signal pin. This went up to 0.51 and down to 0.41 at full stick throw each way. However I'm getting 2.5v at output 2 (FPORT) and no change in value regardless of stick movement. 

Any ideas from anyone on how to troubleshoot? 

Thanks

David

1. Does your Betaflight include FPort. After BF4.2 they made weird system.

2. Are you sure you soldered to FPort pin and working TX pad. Try another tx pad.

3. try SBUS

Thank you Romangpro for the response.

Tried everything you suggested and more. I must be doing something fundamentally wrong. Will go back to the Spektrum receiver and consider a change out if I get a new Tx .
