Setting up and installing bluetooth-raspberry-scanner

Raspberry setup

If you have already setup your raspberry's wifi and ssh, you can skip this

1. Go to raspberry preferences

  • Enable SSH
  • Set WiFi country
  • (Optional: change hostname)

2. Set up network and SSH

  • Connect the raspberry to a network
  • Add your public SSH-key to the raspberry. Easiest way is to use ssh-copy-id
  • SSH will ask for password. The default password is probably raspberry
  • Now you should be able to SSH into the raspberry without password
  • For security, you should disable password authentication from /etc/ssh/sshd_config
  • The change will come to effect after you restart ssh: service ssh restart
  • If you don't, at least change the password

3 Set up bluetoothd

Configure bluetoothd to run with --experimental flag, sudo systemctl edit bluetooth, add section:

[Service]
ExecStart=
ExecStart=/usr/sbin/bluetoothd --experimental

Run sudo systemctl reload bluetooth

Run bluetoothctl

In the new shell:

advertise on (leave the shell open!)

4. Python native dependencies

sudo apt-get install bluetooth libbluetooth-dev

Install PyGObject dependency: https://pygobject.readthedocs.io/en/latest/getting_started.html#ubuntu-getting-started

The project is tested on python 3.5 and python 3.6, verify python version by running python3 --version.

Installing the application

1. Clone the scanner project with git

  • git clone https://github.com/ubikampus/bluetooth-raspberry-scanner.git

2. Install the package

  • python3 -m pip install --user --upgrade .

Configure MQTT_URL (e.g. mqtt.example.com), RASPBERRY_ID and MQTT_PUB_TOPIC in pybluez/pybluez.service file. Copy both /pybluez/pybluez.service and /webbluetooth/webbluetooth.service files to raspberry pi's /etc/systemd/system directory. Run sudo systemctl daemon-reload

3. Start the scanner and web bluetooth server

  1. sudo systemctl enable pybluez
  2. sudo systemctl start pybluez
  3. sudo systemctl enable webbluetooth
  4. sudo systemctl start webbluetooth

Verify service statuses with systemctl status pybluez or systemctl status webbluetooth
