gatt

I'm trying to set up an app to behave as a BLE peripheral device using the Android 5.0 (21) api. So far, I've set up the server, got advertising and connections working, set up custom GATT services and characteristics, and can read and write between the peripheral device and other testing devices. Now I'm trying to add notifications to a few of the parameters but simply put; they're not working. When defining these characteristics, they include the notify property: BluetoothGattService battService = new BluetoothGattService(BatteryProfile.UUID_BATTERY_SERVICE, BluetoothGattService.SERVICE_TYPE

I have an application that working well on Android 4.3 and 4.4. The application will connect and communicate with a custom bluetooth device. After I flashed my Nexus 5 to Lollipop suddenly the I can't connect to the device at all. The connection result always 133. This is the log : D/BluetoothGatt﹕ connect() - device: 00:07:80:04:1A:5A, auto: true D/BluetoothGatt﹕ registerApp() D/BluetoothGatt﹕ registerApp() - UUID=xxxxxx-xxxx-xxxxx-xxxx-xxxxxxxx D/BluetoothGatt﹕ onClientRegistered() - status=0 clientIf=6 D/BluetoothGatt﹕ onClientConnectionState() - status=133 clientIf=6 device=00:07:80:04:1A

I'm attempting to use GATT on my Linux box to set up a custom service with a load of characteristics. Using this question , and the ones it links to, I was able to identify the code that I would need to write (making use of the gatt_service_add() function). I've created a separate file called gatt_service.c, and written the code I think that I need. However, I cannot work out how to link my code to the Bluez libraries in order to compile and run my solution. For example this site (whilst not being for BLE development) links against libbluetooth using -lbluetooth as a gcc parameter, and I

The BluetoothLeGatt Android BLE example contains the following code: public void setCharacteristicNotification(BluetoothGattCharacteristic characteristic, boolean enabled) { if (mBluetoothAdapter == null || mBluetoothGatt == null) { Log.w(TAG, "BluetoothAdapter not initialized"); return; } mBluetoothGatt.setCharacteristicNotification(characteristic, enabled); // This is specific to Heart Rate Measurement. if (UUID_HEART_RATE_MEASUREMENT.equals(characteristic.getUuid())) { BluetoothGattDescriptor descriptor = characteristic.getDescriptor( UUID.fromString(SampleGattAttributes.CLIENT

I am trying to use the BlueZ stack on a Linux machine to create a GATT server with custom services and characteristics. The final goal is to use any central device (e.g. iOS or Android device) to connect to the GATT server, discover the services and characteristics, and manipulate the data in the characteristics. Example: Peripheral with 1 service which contains 3 characteristics. Service uuid = 0xFFFF Char 1 uuid = 0xAAAA, properties = readable Char 2 uuid = 0xBBBB, properties = readable & writable Char 3 uuid = 0xCCCC, properties = notifiable From the central device, I should see the the
