Who can provide A8 wifi module vid/did

#1

AFAIK, raxda changed the vendor id & device id
who own one, can provide it
run
lspci -n can see this

#2

I believe it’s 10ec:b852 for WiFi, and 0bda:b85b for Bluetooth.

#3

can’t find 10ec:b852 in img file
0bda:b85b showed twice

#4

Welp…

thanks
but that confuse me
I got a 8852 module from lenovo laptop, with 10EC:B852
it doesn’t work on rock 5b android build

#7

I’ve got an rtl8852be pulled from an HP laptop, and I had to use a root shell on Android to load the module and kick the UI. (Adb works out of the box, very a serial console works, and of course you can install Magisk, too.)

#9

can you tell more detail how to do this?
did some search, find no solution
and does the bt works?

#10

The simplest way:

From a device that you can open an ADB shell to the Rock 5B (you can do this over a USB-C connection, FWIW):

su
insmod `find /vendor/lib/modules -name 8852be.ko`
stop && start

It’s a bit more involved to make it persistent - it requires patching the vendor image so it loads the module, or doing a custom AOSP build.

And as I recall, Bluetooth did work, but I really didn’t use it because I already had a keyboard and mouse plugged in.

#11

that works for wifi, thanks a lot
but as 8852be.ko is listed in modules.load file
why didn’t it load automatically?

RadxaRock5B:/ # cat /vendor/lib/modules/modules.load
r8168.ko
r8125.ko
8852be.ko
bcmdhd.ko
dhd_static_buf.ko
#12

because this is not in the build

{“RTL8852BE”, “10ec:b852”}," in frameworks/opt/net/wifi/libwifi_hal/rk_wifi_ctrl.cpp

#13

Hello, I faced the same issue - is there a way to get rtl8852be working automatically after Android gets booted?
