Detailed Description

Queue for the Bluetooth LE GATT requests.

The Bluetooth LE GATT Queue module can be used to queue GATT requests if the SoftDevice is not able to handle them at the moment. In this case, processing of the queued request is postponed. Later on, when the corresponding event indicates that the SoftDevice may be free, the request is retried.
