Bluetooth connectivity using Raspberry pi3

[nitz.j2412]

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);
    });
});
}	

});

// Receive data using the 'data' event.
nrfuart.prototype.onData = function(data) {

    this.emit("data", data);
};

// Send data like this

        self.notifyCharacteristic(NRFUART_SERVICE_UUID,
            NRFUART_NOTIFY_CHAR, true, self.onData.bind(self), callback);
    });
};

// export device
module.exports = nrfuart;

bleEchoTst.js

Module.register("bleEchoTst",{
	temper: '999',
	defaults: {
	text: '100'
	},

	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
