Here's the update on the telemetry mirroring with Frsky R9M (converted to ELRS).
I flashed the R9m module with latest ELRS FW so I can mirror CRSF telemetry. To relay the telemetry data, I installed a HM10 Bluetooth 4.0 module on the free uart port of a Frsky taranis X9D+. Note that I needed to put an inverter inline with the serial out to make this work. On the tracker, I also installed another HM10 module to pair with the one on the X9D+ radio.
test configuration:
elrs packet rate = 100Hz
telemetry ratio = 1:4
results:
the tracker setup works, although I noticed it to be a little unstable on 100Hz, yielding fluctuations on the CRSF data fed to the tracker.. On my happymodel es24tx elrs (2.4GHz), 100Hz is stable though. apparently on this R9m ELRS, 100Hz doesn't seem to be ideal, resulting to packet loss.
workaround:
I found that raising the packet rate to 200Hz, and this gave me a more stable CRSF Data, getting 100% max unlike when I used 100Hz on the initial test
conclusion:
frsky R9M converted to ELRS for CRSF Telemetry mirroring was a success!
