MAC layer is now a class rather than being a blob. In addition to that Mac commands are now being handled in a seperate subsystem (a class of its own). In future we will do the same with othe sublayers of MAC like MLME, MCPS etc. The drive behind this exercise is to make MAC and supporting layers into an object oriented system. Major bug fixes include: - last join time inclusion in band parameters - disabling rx2 window if we missed the slot already - MLME uplink schdule hook - nbRep according to spec - maintaining datarate after successful joining - suppressing MLME requests if MAC is in TX_DELAYED state - Uplink dwell time verification Some missing features are implemented. Details are as follows. Support for LinkCheckRequet: An application API is added, add_link_check_request() to delegate a request for Link Check Request MAC command. * Application provides a callback function that needs to be called on reception of link check response. * Mac command is piggybacked with data frames. This API makes the sticky MAC command stick with the application payloads until/unless the application un-sticks the said mac command using remove_link_check_request() API. Handling fPending bit: If in the Downlink, we get the fPending bit set in fctrl octet, we attempt to send an empty message back to Network Server to open additional Receive windows. This operation is independent of the application. An RX_DONE event is queued bedore generating the said empty message. Specification does not mention what can be the type of that empty message. We have decided it to be of CONFIRMED type as it gives us an added benefit of retries if the corresponding RX slots are missed. Radio event callbacks as Mbed callbacks: radio_events_t structure has been carrying C-style callbacks which was inherited from the legacy code. These callbacks has now been changed to Mbed Callbacks that makes sure that we can be object oriented from now on. |
