Tv box x3 mini, wifi and bluetooth do not work


I would really appreciate if you can help me with my problem.

Install the latest version of coreelec to date on a tv box (X3 mini 4gb ram and 32gb storage, bluetooth, dual wifi, amlogic s905x3 processor).
I boot it through a 16gb micro sd, the problem is that it does not recognize neither the bluetooth, nor the wifi.

I am new to this but if you explain it to me I can understand.

I hope your support, thanks. x3 mini

According to board photos over at Freaktab, the AP6255 is used.

Which DTB are you using?

I am using this sm1_s905x3_2g, however I don’t know how to apply the drivers for the AP6255 chip.

You can check what chip you have by running
udevadm info /sys/bus/sdio/devices/sdio*

Would sm1_s905x3_4g not also be the correct DTB for this model?

CoreELEC:~ # udevadm info /sys/bus/sdio/devices/sdio*
P: /devices/platform/ffe03000.sdio/mmc_host/sdio/sdio:0001/sdio:0001:1

Yes, I tried it, but with that he didn’t even give a video

So maybe a box with a fake amount of RAM.

Looks like you have a RTL8821CS WiFi/BT combo.

The RTL8821CU seems supported but I see no mention of the CS variety but I’m sure that the CE team will confirm.
