After assembling an Holybro QAV250 kit I was trying to connect to the drone using the Holybro telemetry module (433MHz) using QGroundControl. I tried in a room with the drone close to the transceiver and I couldn’t connect. But then I puted the drone and the transceiver in opposite corners of the room and it connected and disconnected right away. Then I went outside and tried again and no luck.
Can anyone help me?
That’s weird. Do the indication LEDs on the telemetry module indicate anything?
When I connect to PC the the green led blinks, when I start the QGC the green blinks alternating with the red ones.
It blinks the red but it blinks the green alternating with the red…so I think that it’s transmitting data.
I’ve had similar issues. There seems to be some relation to the physical USB port on the QGC computer that I plug the SiK into. Doesn’t seem to be any rhyme, reason or pattern with it. Totally random from what I can tell. Annoying, but I always get it to work on one of the four USB ports after trying each one.
