Use $timeout, It's working for me. 使用$ 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);

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

This problem is more or less linked to the fact that $cordovaBluetoothSerial isn't available when you are trying to use it. 这个问题或多或少与您尝试使用它时无法使用$ cordovaBluetoothSerial这一事实有关。
Also you need to make sure that you are not testing on your browser, because it won't work! 此外，您需要确保您没有在浏览器上进行测试，因为它不起作用！ Test on a proper Android or iOS device. 在适当的Android或iOS设备上测试。
