    Hello s d2,

    It appears the ZC is a third-party solution, is it using the Zigbee 3.0 Specification?  It is odd that this coordinator creates an all-0xAA PAN ID and transports a NWK key of 0x00.  The Ubiqua log displays a lack of the TC link key update procedure which is unexpected for the Zigbee 3.0 Specification, it appears the ZED is sending an Update Key packet that is acknowledged but not responded to.  You may try setting requestNewTrustCenterLinkKey to FALSE if attempting to join a legacy Zigbee network.  Please make sure to erase all flash memory before programming and clean/rebuild projects if making any firmware changes.

    Regards,
    Ryan

    I work it out, it appears that on coordinator TC link key is disabled so i needed to disable TC link key exchange on ZED device which turned out to be not quite easy to do. Beside disabling preprocessors directives i needed to disable TC keys exchange on several places in code. Anyway thanks on your help.
