we don’t use bluetooth on our custom carrier board
the template for our board was an ixora carrier board
when using the existing apalis devicetree (no matter which one) appears on the console output:
Bluetooth: hci0: unexpected event for opcode 0x0000
has anyone been able to turn this off?
Hello @gerko,
Thanks for reaching out to us!
This error message can be usually disregarded, but if you would really like to get rid of it, you could blacklist the Bluetooth module btusb from loading by adding it into the /etc/modprobe.d/blacklist.conf file and then rebooting the module as explained here: https://linuxconfig.org/how-to-blacklist-a-module-on-ubuntu-debian-linux
Please note that by doing so, you are disabling the Bluetooth module. Let me know how it goes 
Worked.
Thanks a lot for this!
