Connect BLE device using bluetooth with android phone

An application can scan for a particular type of Bluetooth LE devices using ScanFilter . It can also request different types of callbacks for delivering the result.

Features

• Connect device with device name.
• Connect device with Mac address.
• Connect device with service UUID.
• When device connected it will run in background.
• Also it will show the connection status.
• Can read and write data to device.
• Can get battery level of device.

How it works:

1. Gradle Dependency

2. Add the JitPack repository to your project's build.gradle file

    allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

• Add the dependency in your app's build.gradle file

    dependencies {
        implementation 'com.github.TecOrb-Developers:ConnectBluetoothBLEDevice:0.1.0'
    }

1. Add permission

   Manifest.permission.ACCESS_FINE_LOCATION
   Manifest.permission.BLUETOOTH
   Manifest.permission.BLUETOOTH_ADMIN
   Manifest.permission.FOREGROUND_SERVICE
   

2. Connect device with name

   DialogScanningUUID.
       newInstance("", "", "device name here", 
               new DialogScanningUUID.ConnectDeviceCallBack() {
                        @Override
                        public void onRequestToBLEDevice(String macAddress) {
                              startActivity(new Intent(context,ActivityConnectDevice.class)
                              .putExtra("macAddress",macAddress));
                              finish();
                            }
                         @Override
                         public void onCloseCalled() {}
                }).show(getSupportFragmentManager(),"BleDevice");
   

3. Connect device with Mac address

   DialogScanningUUID.
       newInstance("", "enter address here", "", 
               new DialogScanningUUID.ConnectDeviceCallBack() {
                        @Override
                        public void onRequestToBLEDevice(String macAddress) {
                              startActivity(new Intent(context,ActivityConnectDevice.class)
                              .putExtra("macAddress",macAddress));
                              finish();
                            }
                         @Override
                         public void onCloseCalled() {}
                }).show(getSupportFragmentManager(),"BleDevice");
   

4. Connect device with UUID

   DialogScanningUUID.
       newInstance("enter UUID", "", "", 
               new DialogScanningUUID.ConnectDeviceCallBack() {
                        @Override
                        public void onRequestToBLEDevice(String macAddress) {
                              startActivity(new Intent(context,ActivityConnectDevice.class)
                              .putExtra("macAddress",macAddress));
                              finish();
                            }
                         @Override
                         public void onCloseCalled() {}
                }).show(getSupportFragmentManager(),"BleDevice");
   

5. Call backs returns ```

6. CharacteristicsReceivedCallBacks

@Override public void onRotationCountReading(String count) { if (!HRValidationHelper.isNull(count)){ binding.textView.setText("Total Count : "+count); } }

@Override
public void onBatteryReading(String batteryLevel) {
    if (!HRValidationHelper.isNull(batteryLevel)){
        binding.textView3.setText("Battery Level : "+batteryLevel+"%");
    }
}

@Override
public void onConnected(String connectionStatus) {
    if (!HRValidationHelper.isNull(connectionStatus)){
        if (Boolean.parseBoolean(connectionStatus)){
            binding.textView4.setText("Connected");
            binding.textView4.setTextColor(Color.GREEN);
        }else {
            binding.textView4.setText("Failed");
            binding.textView4.setTextColor(Color.RED);
        }
    }
}

```
