Bluetooth Issues with HA Yellow

Hi All,

Having a lot of issues with my bluetooth lately, I use the build in hardware in the HA Yellow. It’s been failing a lot recently and then only works again if I delete the integration, restart HA and let it detect and install again. Only for it to fail a few days later again. And now its showing the following warning:
Bluetooth adapter requires system power cycle

Warning · Reported by Bluetooth

The Bluetooth adapter hci0 (D8:3A:DD:AB:C2:C3) (bcm43438-bt) is stuck in passive scanning mode despite requesting active scanning mode. Automatic recovery was attempted but failed. This is likely a kernel, firmware, or operating system issue, and the system requires a complete power cycle to recover the adapter.

In passive mode, the adapter can only receive advertisements but cannot request additional data from devices, which will affect device discovery and functionality.

Manual intervention required:

  1. Shut down the system completely (not just a reboot)
  2. Remove power (unplug or turn off at the switch)
  3. Wait 10 seconds
  4. Restore power and boot the system

If the issue persists after power cycling:

  • Check for kernel/firmware updates
  • The onboard Bluetooth adapter may have hardware issues

Any help would be really appreciated!
best regards!

Might not be what you’re wanting to hear, but read this.

Get a cheap $3 ESP32 and use it as a bluetooth proxy instead of the adapter in your yellow. Setting it up as a proxy is as simple as connecting a USB cable to it from your PC and flashing it with the wizard Ready-Made Projects - ESPHome - Smart Home Made Simple
