Update

Update a device record

Update will alter the device record in Meshblu. Allows the use of $set, $inc, $push, etc. operators as documented in the MongoDB API

var ws = new WebSocket("wss://meshblu.octoblu.com/ws/v2");

ws.send(JSON.stringify([
  "update",
  [
    {
        "uuid":"26de691f-8068-4cdc-907a-4cb5961a1aba",
        "token":"2e924d1a9cad175ba91f120ede720d50010cd966"
    },
    {
      "$set": {
        "color": "blue"
      }
    }
  ]
]));
var MeshbluWebsocket = require('meshblu-websocket');
var MeshbluConfig = require('meshblu-config');

var meshbluConfig = new MeshbluConfig().toJSON();
var meshblu = new MeshbluWebsocket(meshbluConfig);

meshblu.connect(function(error){
  if (error) {
    console.error(error.message);
  }

  meshblu.subscribe({uuid: meshbluConfig.uuid});

  meshblu.on('config', function(data){
    console.log('config', data);
  });

  meshblu.updateDangerously({
    uuid: meshbluConfig.uuid,
    token: meshbluConfig.token
  }, {
    '$push': {
      stuff: {
        foo: 'bar'
      }
    }
  });
});

❗️

Risk of Token Deletion

If a request is made without any operators prefixed by '$', it is assumed to be the new, full representation of the device. This means that all operators that are not mentioned, such as the token, will be unset.

var ws = new WebSocket("wss://meshblu.octoblu.com/ws/v2");

ws.send(JSON.stringify([
  "update",
  [
    {
        "uuid":"26de691f-8068-4cdc-907a-4cb5961a1aba",
        "token":"2e924d1a9cad175ba91f120ede720d50010cd966"
    },
    {
      "name": "in deep, deep trouble"
    }
  ]
]));
  
# This will unset the token and owner, making the device completely unaccessible!
