berrynet for Debian
------------------

## Simple HOWTO

1. Install mosquitto
```
apt install mosquitto
```

2. Download model
```
cd /tmp
wget https://pjreddie.com/media/files/yolov3-tiny.weights
```

3. Run bn_camera
```
bn_camera --stream-src /dev/video0 --debug
```
Now the program captures images from /dev/video0 and send it to your
local mosquitto (MQTT broker).

4. Run darknet
```
bn_darknet -l /usr/share/darknet/data/coco.names -m /tmp/yolov3-tiny.weights --debug
```

5. Run simple dashboard
```
bn_dashboard --debug --no-full-screen --topic berrynet/engine/darknet/result
```
You should see the results in a window.

## berrynet-dashboard (Freeboard)

If using together with mosquitto, berrynet-dashboard is using websocket.
But mosquitto default does not enable websocket. Thus we have to enable
it manually.
So we need to put a config file to /etc/mosquitto/conf.d

```
# run as root
cat <<EOF >/etc/mosquitto/conf.d
# Listen on port 1883 and websockets

# default listener
port 1883

# extra listener
listener 3000
protocol websockets
EOF
```
