These are older Wifi 5 chips. RTL8821AU is 1x1, with or without Bluetooth. RTL8812AU is 2x2, without Bluetooth. Beamforming is not implemented. It looks like these chips need a different implementation than what is in bf.c. Speed tests with RTL8821AU: 137 Mbps download, 144 Mbps upload. Speed tests with RTL8812AU: 344 Mbps download, 387 Mbps upload. Station mode and AP mode were tested. Bluetooth coexistence works. I used my Bluetooth headphones for several days, listening to music and watching videos. There is only a problem with the wifi speeds with one router: With ISP's HG6544C router: Official driver: 3/5 Mbps. rtw88: a bit more, but not steady at all. Not enough to watch a 1080p Youtube video. With my D-Link Eagle R32 router running Openwrt, on the same channel: Official driver: 6/10 Mbps. rtw88: download starts around 30, climbs to 50 / upload is 10 Mbps. I can watch a 1080p Youtube video. The music doesn't cut out during any speed tests. I also tested transferring files to and from my phone. I don't have other types of Bluetooth devices to test.
