HS4-PI bluetooth doesn't work

[Roger D]

The Raspberry Pi 4 with the Z-Wave hat can co-exist without problems. I ran mine that way for over a year.

I thought I read somewhere that you couldn't have Bluetooth enabled and the Z-Wave hat installed because they used the same serial connection? I suspect that's why BT is disabled by default. Since you are using a Pi4 (not a Hometroller hub) you should be fine.

Thanks for the response. What I have learned is that the installation image from HomeSeer turns off Bluetooth so as not to interfere with Z-Wave. There was no way that I could get it turned on. True or not, what I did was to install a standard RPi OS and then install the HomeSeer program. In this case, Bluetooth is functional.

Do this to enable bluetooth:

sudo nano /boot/config.txt

add this 2 lines:

enable_uart=1

dtoverlay=pi3-miniuart-bt

I have RPi-4 running HS4 and, of course, the Bluetooth has been inactivated. I followed instructions on this thread and have gotten this far:

homeseer@HS4PiV6:~ $ sudo systemctl status bluetooth

However, I also get this:

homeseer@HS4PiV6:~ $ sudo bluetoothctl
Agent registered
[bluetooth]# scan on
No default controller available

So, the Bluetooth device is not being seen by the RPi and Bluetooth is not working. Any help would be appreciated. Thanks.

Yes, HS4 is also working with raspberry pi OS desktop, not only lite OS, usually bluetooth works better on desktop.

Ah I see, I’m running headless under a caravan front bench so can’t do that. However I have up, undid al gte changes and plugged in a usb Bluetooth single and it all just worked

[PFL]

I'm confused what you mean? I'm using a raspberry PI 4 and HS4 for raspberry PI?

Did you tried the desktop version OS?

Hi I ran that. completed without errors rebooted but still get the same no such device result. Also hcitool dev is empty, result of bluetooth status is this.

Yes, but you still need to do this:


sudo apt install bluetooth pi-bluetooth bluez blueman

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

[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

edit bluetooth.service

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

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

Thanks. My image which contains both raspbian and HS4 that I downloaded did not have bluetooth installed.

I was wrong. It was already installed.


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

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.
