OpenWRT installation

Execute the following commands in the terminal:

opkg update
opkg install python3-pip python3-asyncio
pip3 install git+https://github.com/hbldh/bleak.git@f50a334e1173b27a8cf0a53d8ac56d9acc24fedf#egg=bleak
pip3 install -U ble2mqtt

Create the configuration file in /etc/ble2mqtt.json and append your devices.

Bluetooth must be turned on.

hciconfig hci0 up

Run the service in background

ble2mqtt 2> /tmp/ble2mqtt.log &

Container

Build the image as:

podman build -t ble2mqtt:dev .

Start the container and share the config file and DBus for Bluetooth connectivity:

podman run \
-d \
--net=host \
-v $PWD/ble2mqtt.json.sample:/etc/ble2mqtt.json:z \
-v /var/run/dbus:/var/run/dbus:z \
ble2mqtt:dev

Instead of sharing /var/run/dbus, you can export DBUS_SYSTEM_BUS_ADDRESS.

NOTE: --net=host is required as it needs to use the bluetooth interface
