drone boat client

This is the application set for a two motors driven boat.

WORK IN PROGRESS
Using Node.js 12 with the experimental modules feature.

That works at the moment:

• managing accesspoint
• managing dns server
• mqtt broker
• joystick control
• controlling two motor drivers via mqtt on a nodeMCU
• gps
• app splitting, any app acts as mqtt client

Starting

The app is splitted in three apps at the moment:

brain

• MQTT Broker
• GPS
• Switches (light)

npm run dev

networking

• hostapd (wifi accesspoint)
• dnsmasq (dns server)

npm run network

control

• joystick

npm run control

Every app act as mqtt client.

MQTT Clients (clientId)

node app

• boat
• network

    "name":"throttle",
    "value":39,
    "side":{
        "left":39,

    }
}

}

• gps

{
    "lat":52.549405,
    "lon":13.198883333333333,
    "time":"2019-8-20 10:57:46",
    "timestamp":1566291466000,
    "milliseconds":"6000",
    "speed":0
}

• network

{
    "subject":"client",
    "action":"disconnected"
}

client means a wifi client
action can be connected and disconnected
