hi    I can not connect a galaxy tab A bluetooth with some others device by using cordova-plugin-bluetooth-serial. I am using Javascript actions and it's a hybrid app I used to connect them like month ago but somehow i can not connect it anymore. i tried using both bluetoothserial.connectInsecure and bluetoothserial.connect     i did convert my project from 7.23.3 to 7.23.6 and also update my hardware’s software.. so i am not quite sure if those might cause me this problem but the device still be able to connected with the different app correctly, such as Bluetooth terminal app   any advice would be nice.. i am trying to get my hybrid app connect with my hardware via bluetooth again   // this is a connecting part.. it always say that Device connection was lost function ConnectBluetoothDevice(address) { // BEGIN USER CODE if(address == "" || address == null){ alert("No address"); return Promise.reject(false); } else { bluetoothSerial.connectInsecure(address, function(){ return Promise.resolve(true); }, function(error){ alert(error); return Promise.reject(false); }); } // END USER CODE } //This part is always say that Device is connected after that first attempt //to connect even though it's not connected at all function DeviceIsConnected() { // BEGIN USER CODE return new Promise(function(resolve){ bluetoothSerial.isConnected( function() { resolve(true); }, function(error) { alert(error); resolve(false); } ); } ); // END USER CODE }
