Not connecting to QGroundControl for initial setup

if i use adupilot’s firmware QGC recognizes it, but not PX4’s? why?

OK…i have a herelink…what i suggest is install mission planner in your PC and try again. But first open the px4 drone thro mission planner

I agree, when connecting FC with thro mission planner software, the FC loaded with PX4 firmware can be recognized.

then do the previous step that i suggested like going to device manager …

Thank you. Tomorrow morning I will follow your instructions.

hi, in this case, go to device manager, click view =====> show hidden devices -----> go to PORTS and delete COM6 . it looks like COM6 is already used or locked fosome other device. Then try again

what happens when you delete the com 6 from device manager


When I delete it, nothing happens, until I plug it back in the usb jack it keeps showing com6

After deleting it, you must start qgc and start the firmware detection of your drone. Do not restart the computer


I have 2 sets of FC, Pixhawk4 and Duranal V1. both use PX4 firmware, but why it can only go to Pixhawk4’s initial settings but not duranal’s settings.

i know only pixhawk aettings…Good that Pxhawk is working

but i have 1 set of pixhawk6c also same condition as duranal set
