Work out which of the bluetooth adapters to disable. The page goes on to tell you how to automate this with SystemD. In short, you run ‘hciconfig -a’ do find the adapter to disable, then you run ‘hciconfig hci1 down’ to disable that adapter.
I’m using the init.d method from this page.įirst work out which adapter you want to disable. Update 20221029: the old method didn’t seem to run on startup, I’ve added a new method below. This page has a fairly simple method to disable the built in USB adapter. See also the notes under “Disable Built-In Raspberry Pi Bluetooth Adapter 2022.09 and newer” below for an alternate and probably better way to disable bluetooth on startup
sudo apt-get install libcap2 libpcap0.8-dev tcpdumpĭisable Built-In Raspberry Pi Bluetooth Adapter Installing these OS packages seemed to help reduce error messages in the HA logs. Run the “dmesg” command from above to verify the firmware has been found and installed. Once you’ve copied the correct driver onto your Pi reboot the pi with the "sudo reboot" command. Bluetooth: hci0: RTL: firmware file rtl_bt/rtl8761bu_fw.bin not found This should tell you the chipset model and the file you need to find.ĭmesg|egrep -i "blu|hci|bt" bluetooth hci0: Direct firmware load for rtl_bt/rtl8761bu_fw.bin failed with error -2 If you’re not sure which driver you need run the command below and look for messages that contain something like the “not found” message below. Make sure the following line is NOT anywhere in the file. If they don’t have the “.bin” extension when you download them you’ll have to reload it. If you have a different model of Realtek chipset you may find it here or here. To download the firmware / driver for this chipset ssh into your Raspberry Pi and run the following commands. The XSO BT802 appears to have a Realtek RTL8761BU chipset. The error message I was getting in the home assistant user interface wasįailed to start Bluetooth: adapter ‘hci0’ not found
The firmware for this device is not installed in Raspbian by default, so getting it installed is the key. The key problem is that Linux requires a “firmware” / aka Driver to get a piece of hardware working. You may also find my Xiaomi Mijia LYWSD03MMC Tutorial useful. Posts below suggest the ZEXMTE Long Range Bluetooth Adapter has the same chipset, and the process below works for it as well. I had some trouble getting this working on my Raspberry Pi 4 running Raspbian 11 / Bullseye with Home Assistant Core, so while I’m not an expert at either Linux or Bluetooth I thought I’d post how I got this working. It’s on the list of “Known Working Adapters” on the Bluetooth Integration Page. I recently purchased the XDO BT802 from Amazon.
