Hi i am using furiusfpv F35 fc with 1.9.1 firmware with no problem and all telemetry sensors are working and sending values to my horus tx with R9M module and R9 mm receiver the problems start when i upgrade the F35 fc firmware throw the inav configurator to the latest firmware which is 2.01 and TELEMETRY from F35 stop to work throw S.PORT and only RSSI and RECEIVER BATT works my opentx is 2.2.2 and the only thing i didn't test is the latest firmware of the R9m and its r9 receiver maybe this is the problem... any help will be great

@effysh There were changes for port inversion between 1.9.1 and 2.0.1. The R9 MM has both inverted and non-inverted pins. Then there's the issue of the FC, I assume it has an SBUS port that's inverted. With the R9 MM, it's best to use a UART that's not inverted on the FC and the non-inverted pins on the R9 MM.

In addition, posting your INAV dump all would help further.
