我正在尝试将蓝牙集成到我的ionic应用程序中，以便它可以从蓝牙设备接收数据。我试着使用蓝牙插件，但我在PC和android设备上都遇到了一堆错误。我已经使用以下命令安装了bluetoothserial

cordova插件添加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"

这是我的代码

main.html

app.js

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());
}]);

我得到以下错误：

TypeError:无法读取未定义的属性"available"

未捕获引用错误：$cordovaBluetoothSerial未定义

有人能帮忙吗？

使用$timeout，它对我有效。

.controller('BlueController',function ($cordovaBluetoothSerial,$scope,$timeout) {...

$scope.checkBT = function (time) {
  $timeout(function () {
    $cordovaBluetoothSerial.isEnabled().then(fun,fun);
   },time); 
};
$scope.checkBT(750);

尝试

$ionicPlatform.ready(function() {
          $cordovaBluetoothSerial.isEnabled().then(function(){
            $scope.habilitado = true;
              alert('Bluetooth habilitado');
            },function(){
              alert('Bluetooth nao habilitado');
          });
    });

这个问题或多或少与$cordovaBluetoothSerial在您尝试使用它时不可用有关。

此外，你需要确保你没有在浏览器上进行测试，因为它不起作用！在适当的Android或iOS设备上进行测试。
