Hi, I would like to have MSP telemetry in my 9x transmitter, but AFAIK, there is no er9x/openTX version available with MSP support. I found frsky and mavlink versions.
For now I have a Frsky version, but this protocol doesnt have any error control (chksum or similar), so it is unusable for further applications (as ground station maps or antenna trackers).
Does anybody know another way to accomplish this? Thx.
