Abstract

A method for delivering data frames from a source device (702) to a Zigbee end device, ZED, (550) via a Zigbee router, ZR, (510), comprises, at the ZR, receiving individual data blocks with a fragmentation window of '1' data block between the ZR and the source, individually transmitting an APS acknowledgement for received data blocks identified by APS transmission parameters. Data blocks are re-transmitted until an acknowledgement of a successful receipt is transmitted to the source. The data block is transmitted to the ZED until an acknowledgement is received. Following a penultimate data block (720) having been transmitted from the ZR and acknowledged by the ZED, the method further comprises at the ZED: transmitting a second data request (762, 772) to the ZR for a final data block; and transmitting an APS acknowledgement of successfully receiving the final data block to the ZR; and to the source.
