Until there is confirmation that one driver is exactly what needed I’m not doing more builds.

I went back to test with version 20.3, now I have packed it, go back to replace it to see, now I am afraid that the configuration file is wrong, affecting the normal operation.
please look at the makefiles and you will see that they are the same drivers, the same content of the makefile
@vpeter, I understand your frustration with the (somewhat) blind poking in the dark and the iterative build-test-feedback loop that wastes time you’d rather spend on things you enjoy, but I humbly ask you to understand our situation as well.
@rozowy spent a significant amount of time to make a small miracle happen. As you undoubtedly know from your own experience, getting any kind of sources (or additional information) from Chinese manufacturers is not a trivial task by any measure.
As for me, I know little about Linux, but I spent several hours of my own time setting up Android terminal, getting that dmesg output to my PC, poking around in it, separating the files used by the Android driver (or at least, files with the same names) into an archive, uploading everything, writing a nice post, etc.
All this despite the fact that my CoreELEC box is connected via Ethernet and I don’t really need that Wi-Fi chip to work (Bluetooth would be nice though, but not essential). I’m doing it for the community (and also for my own perfectionist sense of “completeness” :). And, of course, I’m ready to volunteer my time and effort to perform any testing necessary and provide any additional information I can.
This is far from a low-effort post, you see.
Besides, we really only have one shot at this. I’ve narrowed down the selection to one specific driver and firmware version for one specific device and made sure that is what a working Android implementation uses (again, I know little about Linux, but that’s what I saw in that dmesg output).
So can we have our one shot, please? 
PS. I’m adding a machine-translated English version of the Lierda UB6X Linux Driver Application Guide. The translation was done by DeepL and looks quite decent to me (a translator with 20 years experience, not with Chinese though :).

I found a problem, an ap6275s driver, but I use the ap6275p driver, these two are different.
@vpeter Hope to have time to do an ap6275p reconstruction, testing, I think it is certainly possible, because I specially extracted from the Tencent Aurora 4pro card brush package, thank you coreelec team.

Please help me add Bluetooth driver, thank you.

can anybody help me
hello do you solve the problem?
only driver include which means you need to copy firmware manually to device
check if modules are loaded and if not follow the instructions you posted to manually load them

I may be barking up the wrong tree because I’m a Linux n00b, but cfg80211.ko seems to be missing, and Chapter 5.3.1 in the Driver Application Guide says the WiFi driver depends on it.
see command
modprobe cfg80211
returns nothing
the same with me
i did it according to this thread
https://doc.wsn.lierda.com/pages/viewpage.action?pageId=30904286
Because this is build-in kernel module and no need to load it manually.
All right, this is clearly out of my league. I’ll watch from the sidelines while you big guys handle it.
When you think I can help, just tell me what to do.
The wifi and Bluetooth chips used by Tencent Aurora 4pro are:SparkLAN AP6275P - 802.11ax + BT, mPCIe (Wi-Fi), UART/PCM (BT) • Broadcom BCM43752.
I’d like to keep testing this MT7668 driver for the BT BR/EDR functionality with my test kernel. How can I include this in my kernel compilation?
