Startup Problems

[Jens-Wymeersch]

I've followed the installation instruction to the letter (https://www.room-assistant.io/guide/quickstart-pi.html#configuring-room-assistant). I've installed the product on an RPI 3B.

I'm getting the following error message :

2/6/2021, 20:57:20 - error - BluetoothService: Inquiring RSSI via BT Classic failed: Command failed: hcitool -i hci0 cc "mac address" && hcitool -i hci0 rssi "mac address" Can't create connection: Operation not permitted Get connection info failed: No such file or directory

My config file is

global:
  instanceName: Master_bedroom
  integrations:
    - homeAssistant
    - bluetoothClassic
homeAssistant:
  mqttUrl: 'mqtt://XX.YY.ZZ.UU:1883'
  mqttOptions:
    username: user
    password: PSW
bluetoothClassic:
  minRssi: -20
  hciDeviceId: 0
  addresses:
    - mac addresses

Please note that when launching room-assistant : all looks good besides the following

ls: cannot access '/dev/disk/by-id/': No such file or directory

Can you please let me know what I'm doing wrong here ?

Can you try running the setcap commands again?

sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)
sudo setcap cap_net_raw+eip $(eval readlink -f `which hcitool`)
sudo setcap cap_net_admin+eip $(eval readlink -f `which hciconfig`)

Usually the operation not permitted error is a sign of missing permissions. Sometimes it may also be that the Bluetooth adapter is in a weird state, which you can usually solve by just rebooting the Pi.

Hello,

Thank you for your quick reply but unfortunately even if I place my phone next to the RPI. I don't see anything happening. What should I do ?

Regards,
Jens

Can you check what the output of hciconfig and hcitool -i hci0 cc "mac address" && hcitool -i hci0 rssi "mac address" is when you run those manually? It's best to turn of room-assistant before you do that so that the hcitool commands don't conflict each other. The first command should return adapter info for hci0 that shows it as "up", the second should ideally return an RSSI strength number.

Also: are you running just one instance of room-assistant or multiple?

hciconfig

I'm currently doing the test with 1. In the future, I expect to have at least 3

I've tried to get it working based on the following treat without success. https://www.raspberrypi.org/forums/viewtopic.php?t=124559
@mKeRix What can I do more ?

Did you ever have any success with this? Was it your bluetooth devices?
I have the same exact issue on 2 different Raspberry Pis - I'd love to know what I am doing wrong.
I performed all troubleshooting steps here and the other linked thread.

Edit 5 days later:
I believe the issue was indeed the bluetooth devices I was trying to track. I decided to try my iPhone and tracking works as expected. My withings HR was never detected by room assistant. Oddly, my wife's Apple watch was never detected, either - I'll have to keep working on that one.
