How to use built-in Rpi 4 bluetooth?

Configuration
22

Could you share your exact model of temperature sensor, I can add it to Theengs gateway and we can do some testing

I have a SwitchBot MeterTH S1. I have added the BLE Monitor integration loaded and I successfully added it with that integration, but the SwitchBot integration now says “no unconfigured devices found” so I guess the BLE Monitor is the only way to get it to work?

24

I am having the same error: When adding the Switchbot integration I get the error “failed to connect” on my Raspberry Pi 3. I cant find any solution.

I am having an issue with my RPi4 bluetooth. I have my system running on a SSD connected to the Pi by usb 3. Are you saying that bluetooth will never work with this. I only used usb 3 because it’s the latest standard. DO I just need to connect my ssd to a usb 2 port instead?

I have just seen this issue discussed on here and so I tried putting my BT device (Switchbot) next to the Pi4 but I still get the same errors (No unconfigured Bluetooth adapters found).

I have tried connecting the ssd to the usb 2 port, but I still get the same result.

Hi zimbrich. I have the same issue. Did you figure it our please?

What do you get when you run hciconfig -a?

If you don’t get anything back and no error, try running this command:

sudo systemctl start hciuart

I have 3 RPI4 and for some reason 1 of them doesn’t start bluetooth on startup but the others do.
Thru a lot of trial and error I finally figured that I had to manually start the BT device before it would work.

After starting hciuart I get a successful response with hciconfig -a

Hope that helps!
