    oK!

    I chek today one more times.
    Some days ago I got next:

    Use ZNP and my application based of GenericDevices with MT.

    The EXPERIMENT 1
    Build net on the table ZC, ZR, ZED. ZED join to ZR. switch of router. Check child table of ZC by UTIL_GET_DEVICE_INFO. I can see rejoin ZED to ZC. It is ok. Then I Start router and check child table of ZR by UTIL_GET_DEVICE_INFO. The table is clear.

    The EXPERIMENT 2 (Is mirror to The EXPERIMENT 1)
    I join ZED to ZC. Switch of ZC. ZED join to ZR. Then I Start ZC and check child table of ZR by UTIL_GET_DEVICE_INFO. I can see my ZED in AssocDeviceList. After about 2 minutes the child table of ZC clear..

    In both case I try to moitor by debuger the ZDApp_SendParentAnnce. l This function is call.

    And the weirdness - right now after start ZC the ZC dose'nt answear UTIL_GET_DEVICE_INFO. About few seconds. And answer other command.

    Hi Pavel,

    Can you detail the exact issue you are experiencing right now? Does it relate to parent announce handling or responding to a UTIL_GET_DEVICE_INFO command? Do you mean that this condition only lasts for a few seconds and are other MT_UTIL commands answered during this time?

    Regards,
    Ryan

    Do you change anything to ZNP source code when you test this?
