Hello, another puzzled RC noob here.
It’s been a learning curve, a lot to take in and understand. I looked for a more specific subcategory, where I could ask system specific questions about my mix of Transmitter (RC Controller) , flight controller, ground control software & communication protocols.
I have posted in Using QGroundControl subcategory, a specific question about GGC. Pretty quiet over there…
I have a nearly complete Tarot hexacopter on which I haven’t been able to test spin the 6 motors.
I believed I’ve narrowed it down to the fact that QGC, running on my Android tablet, can’t “hear” my Taranis X9D Controller.
When I attempt to pass preflight, it fails unless I connect the PixHawk flight controller directly to GGC with a USB cable. Even so, QGC insists “Not Connected” and the Transmitter icon is gray.
When I try to Calibrate the joysticks using QGC, I get an error message
"0 channels detected. PixHawk needs at least 5 channels’
I’ve searched that error message online with few results, no solutions
I have 8 channels configured in the X9D so far. And please note I get good RSSI readings between the X9D controller and the Receivers onboard the hexcopter.
I do have the WiFi enabled on the tablet, but maybe I need some specific antenna for the X9D to communicate (using radios frequencies) with the tablet (running GGC)?
QGC informs me on the Radio setup menu that it “already knows” most common comm protocols. But maybe it needs extra hardware to communicate?
Maybe my theory is completely off track. Any thoughts? Thanks.
