/**
* Queue length of BLE Event
* This parameter defines the number of asynchronous events that can be stored in the HCI layer before
* being reported to the application. When a command is sent to the BLE core coprocessor, the HCI layer
* is waiting for the event with the Num_HCI_Command_Packets set to 1. The receive queue shall be large
* enough to store all asynchronous events received in between.
* When CFG_TLBLE_MOST_EVENT_PAYLOAD_SIZE is set to 27, this allow to store three 255 bytes long asynchronous events
* between the HCI command and its event.
* This parameter depends on the value given to CFG_TLBLE_MOST_EVENT_PAYLOAD_SIZE. When the queue size is to small,
* the system may hang if the queue is full with asynchronous events and the HCI layer is still waiting
* for a CC/CS event, In that case, the notification TL_BLE_HCI_ToNot() is called to indicate
* to the application a HCI command did not receive its command event within 30s (Default HCI Timeout).
