HS4-PI bluetooth doesn't work

[jasv]

I downloaded HS4-pi and created an image. HS4 works perfectly. I want to use a bluetooth keyboard but bluetooth was not installed.
I ran

 sudo apt install bluetooth pi-bluetooth bluez blueman

and everything installed without error and rebooted. But bluetoothctl hangs with or without using sudo.
I know it isn't a hardware issue because when I use an SD with normal raspbian bluetooth works as expected.

Anyone have any cluses how I can get bluetooth to work on a HS4-PI image?

Do this to enable bluetooth:

sudo nano /boot/config.txt

add this 2 lines:

enable_uart=1

dtoverlay=pi3-miniuart-bt

dtoverlay=pi3-miniuart-bt

I tried that and it did not work. I did not mention that I have a raspberry pi 4 (4gb). I noticed a line that disabled the bluetooth

dtoverlay=pi3-disable-bt

but removing that line did not help either.

Raspberry Pi 2/3 have two UARTs, uart1 and uart0. Raspberry Pi 4 has four additional UARTs available. Only uart0/1 is enabled over GPIO pin 14/15 by default. The additional UARTs can be enabled through the device tree overlays.

1. Edit cmdline.txt and remove "console=serial0,115200" - you don't want Linux to start a console on it.
2. Edit config.txt and add "enable_uart=1".
3. Reboot, start up a terminal emulator (minicom, etc.) and open /dev/ttyS0 at 9600 baud (or whatever baud rate the device is meant to run at).

If for some strange reason this doesn't work, you can use the mini-UART for Bluetooth:

4. Edit config.txt again and add "dtoverlay=miniuart-bt".
5. Reboot, start up a terminal emulator (minicom, etc.) and open /dev/ttyAMA0 at 9600 baud (or whatever baud rate the device is meant to run at).

The cmdline.txt did not have the console=xxx text so there was nothing to remove. I did add the lines you suggested to my config.txt. Still no progress. Here is the status of the bluetooth deamon

Bluetooth is disabled on the HS-Pi build due to it conflicting with the serial interface to the Z-Wave GPIO card. If you're not using that, you might be able to restore the original Raspberry Pi configuration by (1) removing "dtoverlay=pi3-disable-bt" from /boot /config.txt, (2) re-enabling the hciuart service:

sudo systemctl enable hciuart.service

(3) reboot

I did install bluetooth and it's working on my Pi 4B HS4 Box

Thanks. I will try to reflash an image and to try again. My image which contains both raspbian and HS4 that I downloaded did not have bluetooth installed. Did you install it first?

The image from HomeSeer removed bluetooth function due to port conflicts. I reconfigured config.txt and enabled HCI service.

[jasv]

Success! Thank you very much. I've been obsessed.

I was wrong. It was already installed.


Although it is working now, I am getting a couple of errors. Can Ignore them?

edit bluetooth.service

find line and change to /usr/lib/bluetooth/bluetoothd --plugin=a2dp

[trevor-austin]

Edit config.txt

# Enable Bluetooth alternate port

enable_uart=1

#dtoverlay=pi3-miniuart-bt

dtoverlay=uart4

dtoverlay=miniuart-bt

sudo reboot

sudo hciconfig hci0 reset

sudo invoke-rc.d bluetooth restart

Hi, I wonder if you could clarify for me.

Are lines 1-5 added to the end of config.txt? then saved and the remaining 3 lines as separate command lines.

If that is the case I get a fail on sudo hciconfig hci0 reset with a no such device, any further ideas?

Yes, but you still need to do this:


sudo apt install bluetooth pi-bluetooth bluez blueman
