Remarks
An app only sends out one subscription request. The App must collect the list of all devices that require subscriptions and send them out all at once.

Because the Thing-App shares subscriptions with the host and possibly other Thing-Apps. The following behaviors may be observed:
1. The first few data reports may be in response to ReadRequest.
2. The data reports may contain attributes and events that are not subscribed to by this Thing-App.
3. Libertas-OS will handle errors, including timeout. A StatusResponse report will be generated in case of errors.
The report data will be passed to the callback function LibertasDeviceCallback registered with Libertas_SetOnDevice.
