CC2530: Sending commands efficiently

Ra No
Prodigy 70 points

Part Number: CC2530

Hi All. Thank you, Ryan, for accurate replies to my previous questions.

When an end device sends unambiguously addressed commands with zcl_SendCommand, are they always routed through the most efficient path in the mesh (through other devices), or directly to the target end device? If the latter, is there any way to rather use the most efficient path (the one with the strongest signals) but still send commands directly addressed to a particular end device?

    Hi Ra,

    If the ZED is not directly associated to the node, then its Zigbee mesh routing layer will determine the most efficient path to send messages to the ZED.  There is not a method for sending commands directly to a ZED for which the node is not a parent.  You can read more on Zigbee routing from the Z-Stack Overview.  The ZED should only be communicating to the parent for which it is sending Data Requests.

    Regards,
    Ryan
