(Android) Connecting to device with high advertisement intervalhttps://devzone.nordicsemi.com/f/nordic-q-a/20860/android-connecting-to-device-with-high-advertisement-intervalHi, I&#39;m currently working on a BLE device which works his whole lifetime on one battery. This means we have to save as much energy as possible. This is why we set our advertisement interval to 3 seconds. Using the Nordic Connect app this causesen-USTelligent Community 13Tue, 09 May 2017 06:43:22 GMTRE: (Android) Connecting to device with high advertisement intervalhttps://devzone.nordicsemi.com/thread/81464?ContentTypeID=1Tue, 09 May 2017 06:43:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fd4e70cb-b08b-478a-a3e5-1f1527647cbbThomas<p>It took us a while to figure it out. For anyone passing by, as you can see our <code>connect()</code> function takes the mac address as parameter. The mac address is obtained from the BluetoothDevice object of a ScanResult. By only passing the mac address the BluetoothDevice object is discarded. Then in our <code>connect()</code> function we need to obtain it again with <code>mBluetoothAdapter.getRemoteDevice(address)</code>. This process causes the connecting procedure (<code>connectGatt()</code>) to take longer than normal.</p> <p>So use <code>device.connectGatt()</code> directly on the device obtained from the ScanResult.</p><div style="clear:both;"></div>RE: (Android) Connecting to device with high advertisement intervalhttps://devzone.nordicsemi.com/thread/81463?ContentTypeID=1Wed, 29 Mar 2017 07:21:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9e8bc3b5-bc84-4763-8903-b9800e304454Thomas<p>Alright, currently we stop scanning before connecting. We will try keep scanning during connecting!

So you could try to use <a href="https://developer.android.com/reference/android/bluetooth/le/BluetoothLeScanner.html#startScan(java.util.List%3Candroid.bluetooth.le.ScanFilter%3E,%20android.bluetooth.le.ScanSettings,%20android.bluetooth.le.ScanCallback)">BluetoothLeScanner.startScan()</a> with the scan settings set to <code>SCAN_MODE_LOW_LATENCY</code>. This should speed up the connection attempt.</p><div style="clear:both;"></div>
