Hey,
I am setting up a new plane using R9M (FPORT firmware) & and have wired into TX4 (Serial 6). I am able to see control surfaces move but when I discover sensors, only see GPS.
Config is as below;
* `SERIALx_PROTOCOL` =23
* `SERIALx_OPTIONS` = 7 (invert TX/RX,Half Duplex)
* `RSSI_TYPE` =3
Hi, sorry, I know so little about FPort that I can’t provide any assistance. Maybe @andyp1per has some advice…
I don’t do F.Port 
what flight controller is this on?
@craigy72
I am having the exact same problem, i am only seeing GPS, did you find out wagt is the problem?
same issue, only GPS is discovered.
Will try with older firmware as it used to work very well.
