I have been having an issue with trying to get the Pixhawk to connect to QGC. I have had it working many times in the past, zero issues. Now we have been working on a way to power the Raspberry Pi and Pixhawk internally using 5V regulators at first, then moved on to using the BEC from the ESC’s. Not sure if the power source change caused our problems, but after the switch we noticed that it no longer works.
Raspberry Pi works like a charm. I get video feed in QGC. I have bidirectional pings with 0 packet loss. Raspberry Pi is being powered with MicroUSB spliced into motor 5 BEC.
Pixhawk is being powered through the power module port on pin 1 (+5VDC) and pin 5 (GND), going left to right. Not using the included power module because it gets WAY too hot for some reason, so we ditched it. Grounds are all connected to the GND rail on the Pixhawk, this includes GND from Pi, Pixhawk, and all 6 ESC’s. Pixhawk appears to start up fine.
FMU lights: PWR - Solid Green, B/E: Quick red flash for 1-2 seconds.
Main LED indicates standby.
When the Pixhawk is plugged directly into the computer via USB cable, the same start up LED sequence. Windows tell me that the USB device is no recognized. Device manager tell me that the most up to date driver is installed. I have also reinstalled the PX4 drivers from https://pixhawk.org/firmware/downloads. Successful install of that, still no recognition of the device.
Please help me.
