    Hi Alireza Koohgard,

    The processing of the OTA frames changes for each destination layer, for example an APS layer OTA frame sent from node A can have a MAC destination address for node B, NWK destination layer for node C so, the frame received by the node B will be sent by the NWK layer to the node C and when is received the processing will reach the APS layer of the node C.

    I will recommend you to use Ubiqua Protocol Analyzer for example to see the data traffic between your nodes and clearly see how the packet where routed by looking at the layer headers.

    Regarding to the LQI, the value corresponds to the link between the destination node and the neighbor that delivered the frame.

    I hope this helps.


    Best regards.
