Hello Everyone,
Great to be a part of this community. A big thanks to all the contributors and developers.
I built a custom module to connect Adafruit Bluetooth module nrf8001 with the MM2. I am not seeing anything on the mirror and can’t figure out the issue. Please find attached the module files:
node_helper.js
var nrfuart = require('./index.js');
module.exports = NodeHelper.create({
start: function () {
console.log('BLE helper started ...');
},
socketNotificationReceived: function(notification, payload) {
if (notification === 'TEMP') {
console.log('Notification TEMP in ' + this.name + ' received');
this.sendNotificationTest(this.anotherFunction());
}
else
{
console.log('ERRRRROR');
}
},
sendNotificationTest:function(payload){
this.sendSocketNotification('TEMPER',payload);
},
anotherFunction: function(){
nrfuart.discoverAll(function(ble_uart) {
'use strict';
ble_uart.on('disconnect', function() {});
ble_uart.connectAndSetup(function() {
var writeCount = 0;
ble_uart.readDeviceName(function(devName) {});
ble_uart.on('data', function(data) {
var x = data.toString();
var con = x.substring(0,2);
var dec = x.substring(2,4);
con = con.concat('.');
con = con.concat(dec);
console.log(con);
return con;
});
setInterval(function() {}, 3000);
});
});
}
});

bleEchoTst.js
Module.register("bleEchoTst",{
temper: '999',

},
start: function() {
this.temper = this.config.text;
this.sendSocketNotification('TEMP',this.config);
},
socketNotificationReceived: function(notification,payload)
{
if(notification === 'TEMPER')
{
this.temper = payload;
//this.temper = '999';
this.updateDom();
}
},
// Override dom generator.
getDom: function() {
var wrapper = document.createElement("div");
wrapper.innerHTML = this.temper;
return wrapper;
}
});
Any help is appreciated.
Thanks
