Missing CAP_NET_ADMIN permission.. REPOST
-
Against my better judgement - I am attempting AGAIN to use Qt examples "btchat".
After correcting some example code issues I am back to the old and NOT SOLVED problem with " Missing CAP_NET_ADMIN permission."
Going thru past posts - there has been MANY "fixes" to bypass this error. Since I have tried few other ways to work with Bluetooth I feel qualified to state this
"THIS ERROR is posted ONLY by Qt " - and that is not just my opinion , that is a fact.I would like to SERIOUSLY discuss AND SOLVE this Qt usage of "bluez" library error. I am not looking for various hacks to bypass this - I am looking for way to permanently fix this Qt error.
I would very much appreciate if only Bluetooth users/ coders with actual experience with this error reply.
No AI bots are welcome ....I am looking for a SOLUTION, I am not asking for opinions.

I do not know if 6.6 has this fixed. -
