How to get the BLE chip's advertisement raw data on Android APP

[Jenson]

Dear all

Good day!

I want to develop the Android APP to received the BLE's ad raw data(which is dynamic change). Which API should I called to get the raw data? And should I refresh the scan API to get the dynamic data ? Or do you have the demo code for Android APP?

Thanks & Regards Jenson

Hi.

You can find source code for our Smartphone demo apps here.

If you check out the nRF UART app, see line 159 of DeviceListActivity.java:

private BluetoothAdapter.LeScanCallback mLeScanCallback =
            new BluetoothAdapter.LeScanCallback() {

        @Override
        public void onLeScan(final BluetoothDevice device, final int rssi, byte[] scanRecord) {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                	
                	  runOnUiThread(new Runnable() {
                          @Override
                          public void run() {
                              addDevice(device,rssi);
                          }
                      });
                   
                }
            });
        }
    };

The scanrecord byte array contains the advertisement data.

You should check out android's documentation and Scanrecord and bluetooth LE.
