Send and Receive Messages

Connect to Octoblu and send/receive messages
Create a file called "index.js" with the code below: [block:code] { "codes": [ { "code": "var meshblu = require('meshblu');\n\n// Not specifying a UUID/Token auto-registers a new device\nvar conn = meshblu.createConnection({\n \"server\": \"meshblu.octoblu.com\",\n \"port\": 80\n});\n\nconn.on('notReady', function(data){\n console.log('UUID FAILED AUTHENTICATION!');\n console.log(data);\n});\n\nconn.on('ready', function(data){\n console.log('UUID AUTHENTICATED!');\n console.log(data);\n\n setInterval(function(){\n console.log(\"sending message\");\n conn.message({\n \"devices\": data.uuid,\n \"payload\": {\n \"hello\":\"world\"\n }\n });\n },300);\n\n conn.on('message', function(data){\n console.log('message received');\n console.log(data);\n });\n\n});", "language": "javascript" } ] } [/block] Then run: [block:code] { "codes": [ { "code": "node index.js", "language": "text" } ] } [/block] Here is the example output: [block:code] { "codes": [ { "code": "trying ws://meshblu.octoblu.com:80\n UUID AUTHENTICATED!\n { api: 'connect',\n status: 201,\n socketid: 'UMumKQdMAE73j3tXAACr',\n uuid: '5ddfa401-3f62-11e4-9968-a5374769756b',\n token: 'edech445oyt7f1or0c6p5pugovv4pldi' }\n sending message\n message received\n { devices: '5ddfa401-3f62-11e4-9968-a5374769756b',\n payload: { hello: 'world' },\n fromUuid: '5ddfa401-3f62-11e4-9968-a5374769756b' }\n sending message\n message received\n { devices: '5ddfa401-3f62-11e4-9968-a5374769756b',\n payload: { hello: 'world' },\n fromUuid: '5ddfa401-3f62-11e4-9968-a5374769756b' }", "language": "text" } ] } [/block]
