Report Reference in Android

[Artem Zemlyanukhin]

Hello,

In our project we use HID service. The difference between our HID and standart HID is that we use our own UUIDs. Our report charactestics include Report Refernces (0x2908) and CCCD (if it support notification).

We have problem with Android. After devices successfully paired and connected, we call discoverServices() (BluetoothGatt method). Services discovered, but all descriptors are in first characteristic - this causes the problem with subscribing to notifications from others (except first) characteristics. In other words the first characteristic has 12 descriptors and the rest - none.

For example many apps from Play market could not read properly characteristic of ou service (for example "BLE Tool"). But nRF Master Control Panel works good - it reads all characteristics with cccds and report references. Could you provide please sample code how you do service discovery? Or may be you can provide Master Control Pannel source? I found only nRF Toolbox sources.

Best regards, Artem Z

@Artem: Could you send us your project source (could be strip down version, to just initialize the service& characeristics) so that we can test here ? I don't think we use anything other than the API provided by Android mBluetoothGatt.discoverServices() to do service discovery.
