LinkADRReq mac command can be used by the network server to set a certain level of QOS using NbTrans field which is applicable to Unconfirmed traffic only for 1.0.2 spec. This commit introduces mechanisms to facilitate this QOS. It means to repeat an outgoing unconfirmed message NbTrans times without changing its frame counter. For class C, we have retired the ack_expiry_timer_for_class_c and have replaced it with another timer which mimics the RX2 closure as in Class A but doesn't actually close RX2 window. It's just a mechanism by which the state machine is informed that the you can proceed forward, we have not received anything in RX2 window either. This is needed as RX2 doesn't timeout in class C (i.e., the radio remains in continuous mode). In addition to that we need to close any pending timers for Receive windows after the MIC has passed and the Duplicate counter check has also been passed. |
