Unable to connect Blue ROV2 to QGC

Hi @Surya, welcome to the forum :slight_smile:

If a Pixhawk is not showing up then there’s most likely an issue with either

  • the USB-A to micro-USB cable between the Raspberry Pi and Pixhawk
    • there could also be an issue with one of the ports
  • the firmware on the Pixhawk
  • the power supply to the Pixhawk
  • the Pixhawk hardware

Does it show up in QGroundControl if you plug it in directly to the topside computer? If not, try a different cable. If it does, try flashing ArduSub onto it through QGC.

If a different cable doesn’t help then there’s likely something wrong with either the Pixhawk microUSB port (which is by-passable if necessary), or the Pixhawk itself is fried. If the PWR lights are on then it’s at least able to receive power. If the B/E and/or ACT lights flash then the chip is working to at least some degree.
