Help & Support Hardware

Hello,

Since the release of CE 9.2.0 is bluetooth not working anymore on my Mecool KM9 Pro box. I tried with the latest nightly and with some develop builds too, no avail.
It was working with one of the develop builds of the end of august (CoreELEC-Amlogic-ng.arm-9.1-devel-1565360317.tar) found here:
https://mega.nz/#!hW5gHYZQ!la2lnraC2mFUCN0kAMHeSkVfxoJPCgN0AYnzAKZItMQ

The wifi/BT chip is AP6212.
The output of udevadm info /sys/bus/sdio/devices/sdio* | paste is: http://ix.io/1Wc8
Plugged in a cheap usb bluetooth dongle from AliExpress and all is working fine.
Thanks!

Edit: CEC was initially not working as well, but was fixed in this build, which I’m currently running:
CoreELEC-Amlogic-ng.arm-9.2-devel-1570018126.tar

Is there something I can do / add myself. A missing driver or something?
Thanks!

Disconnect the USB dongle, reboot. Then SSH in and run the following commands, then post the output:

echo 0 > /sys/class/rfkill/rfkill0/state
sleep 2
echo 1 > /sys/class/rfkill/rfkill0/state
sleep 2
/usr/bin/hciattach -n -s 115200 /dev/ttyS1 bcm43xx 2000000

Thanks for looking into this.
