I am trying to integrate bluetooth in my ionic app so that it can receive data from a bluetooth device.I tried to use the Bluetooth plugin but I get a bunch of errors both on PC and on android device. I have installed bluetoothserial using the following command
cordova plugin add com.megster.cordova.bluetoothserial
%cordova plugins
com.ionic.keyboard 1.0.4 "Keyboard"
com.megster.cordova.bluetoothserial 0.4.3 "Bluetooth Serial"
cordova-plugin-whitelist 1.0.1-dev "Whitelist"
org.apache.cordova.console 0.2.13 "Console"
org.apache.cordova.device 0.3.0 "Device"
and here is my code
main.html

angular.module('starter' ['ionic','ngCordova','ngRoute','ngTagsInput'])
.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
$cordovaBluetoothSerial.isEnabled().then(
function() {
$cordovaDialogs.alert("Bluetooth LE is enabled", "Bluetooth LE", "GREAT!");
},
function() {
$cordovaDialogs.alert("Bluetooth LE is NOT enabled", "Bluetooth LE", "Oops!");
}
);
if(window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})
.controller('datactr',['$scope','$http' ,'$cordovaBluetoothSerial',function($scope,$http,$cordovaBluetoothSerial) {
console.log($cordovaBluetoothSerial.available());
}]);
I get the following errors:
TypeError: Cannot read property 'available' of undefined
Uncaught ReferenceError: $cordovaBluetoothSerial is not defined
can anyone help?
Try
This problem is more or less linked to the fact that $cordovaBluetoothSerial isn't available when you are trying to use it.
Also you need to make sure that you are not testing on your browser, because it won't work! Test on a proper Android or iOS device.
Use $timeout, It's working for me.
.controller('BlueController',function ($cordovaBluetoothSerial,$scope,$timeout) {...
