Hi,

I've borrowed a Spirit Pro from a friend to try out this brand, and I'm having trouble getting the Integration to work with my RadioMaster TX16S running EdgeTx (v2.10.4).

I'm using an FrSky XSR receiver with S.Port and the Spirit Pro has the latest v4.0.0 firmware.

I found the following post "FrSky integration cable don't work with FrSky TWMX receiver" (viewtopic.php?t=6270&hilit=tx16) which indicates that a similar setup used to work v3.6.2, but stopped working in v3.7.x.

I'm hoping the problem has been fixed in v4.0, but that does no seem to be the case.

I am able to monitor the Tx and Rx pins of the SYS port of the Spirit Pro with my oscilloscope, and I can see that it is receiving data from the FrSky S.port, but the Tx pin on the Spirit Pro has NO response.

Has anybody been able to get the Spirit Pro Integration working with v4.0 firmware?

Any advice would be appreciated!

Thanks.
Andrew
