BluetoothSerial 插件不适用于 ionic

Question

我正在尝试将蓝牙集成到我的 ionic 应用程序中，以便它可以从蓝牙接收数据 device.I 尝试使用蓝牙插件，但我在 PC 和 android 设备。我已经使用以下命令安装了 bluetoothserial

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"

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());
}]);

我收到以下错误：

TypeError: Cannot read property 'available' of undefined

Uncaught ReferenceError: $cordovaBluetoothSerial is not defined

有人可以帮忙吗？

Answer 1

使用 $timeout，它对我有用。

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

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

Answer 2

此问题或多或少与 $cordovaBluetoothSerial 在您尝试使用时不可用有关。

此外，您还需要确保您没有在浏览器上进行测试，因为它不会工作！在合适的 Android 或 iOS 设备上测试。

Answer 3

尝试

$ionicPlatform.ready(function() {

          $cordovaBluetoothSerial.isEnabled().then(function(){
            $scope.habilitado = true;
              alert('Bluetooth habilitado');

            },function(){
              alert('Bluetooth nao habilitado');

          });

    });
