Using cards with RTL8812BU chipset

[massimilianonball]

I use svpcom/wifibroadcast in a 2.4 GHz configurations from months until now without a problem with a pi 3b+ on the drone and another pi 3b+ (or alternatively with a laptop running ubuntu 18.04) as groundstation.

As in the object, i have problem with a couple of 5.8GHz china's wifi adapters that i have recently purchased; the problem is that the description of the products reports RTL8812au as chipset, while i have found that they are the 8812b version..

I have used this drivers below and the wifi adapters are recognized from the system but they won't work with svpcom/wifibroadcast:
https://github.com/cilynx/rtl88x2bu

I paste below some data on my systems (the pi and the laptop as groundstations), on the wifi cards and on the errors.

Is there a way to have those cards working with svpcom/wifibroadcast?

Many thanks!!

[svpcom]

Your driver doesn't support packet injection:

 iw dev wlan1 set monitor otherbss

The easiest solution is to try to refund cards (especially if they are not 8812au).
