I am new to this community. My name is Kay and I come from Essen in Germany. I have recently started out flying drones with my Cheerson CX-20 (APM 2.52) and have since really caught the bug.
Since I already used my Graupner MX-20 for model ships, I also installed the Graupner RX into the Cheerson and have started building my own drone with a mini APM 3.1
Now since I have seen telemetry on a friends Taranis I wanted to include this in my Graupner which allows telemetry with ther HoTT technology and quickly found mavlink2hott.
So I bought an APM328P board, installed the firmware and wired it to the APM mini as follows
TX > RXO
+5V > VIN
GND > GND
Then I wired D3 > T on my Graupner GR-12 RX and set the function to "Sensor" in the telemetry menu.
However, I cannot seem to get any telemetry data from the APM.
There is not even a sensor emulation screen. When in the telemetry menu, I cannot select/deselect any sensors.
One thing I am thinking about right as I am writing this is, that I have only connected the telemetry pin to the RX for testing so far. There is no other connection to the APM as of right now. May that be the problem or did I do anything wrong?
Help would be greatly appreciated!
