    <p>I am using Nexus 4(4.4 kitkat) as central and iPad as peripheral.Peripheral has a service which it is advertising.The advertising packet has some data(22bytes) + service UUID.When I try to scan for the peripheral from Android, iPad peripheral is discovered.However when I try to get the service UUID from scanRecord parameter in the callback, I could not find it.All I get is the 20byte data which the peripheral is sending.When I try to scan for devices with the UUID I am not able to discover those peripherals.</p> <p>Following is the iOS code to advertise a service.The service id being used is "0000192f-0000-1000-8000-00805f9b34fb"</p> <pre><code>CBUUID *serviceUuid = [CBUUID UUIDWithString:TRANSFER_SERVICE_UUID]; [self.peripheralManager startAdvertising:@{CBAdvertisementDataServiceUUIDsKey : @[serviceUuid], CBAdvertisementDataLocalNameKey:[[BTLEConfigs sharedBTLEConfig] getAdvertizingUUID]}]; </code></pre> <p>The device gets discovered when I scan without service UUID.</p> <pre><code>// Device scan callback. private BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback() { @Override public void onLeScan(final BluetoothDevice device, int rssi, final byte[] scanRecord) { runOnUiThread(new Runnable() { @Override public void run() { //-- how to retrieve the service id from scanRecord } }); } }; </code></pre> <p>The services are discovered between two iOS devices but between Android device and iOS peripheral its not working.How to scan a peripheral with 16bit service UUID?Any help is appreciated.</p>

    2. COFinally I was able to get the service UUID from the scanRecord.This link helped me - http://stackoverflow.com/a/19060589/662025.But still I wonder how to scan the sensors with 16bit UUIDs.

    3. COHave you tried using TRANSFER_SERVICE_UUID=@"192f" ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
