     * to the request are stored in the trust center cache portion of the
     * address table. Note that you need at least 1 entry allocated for
     * TC cache in the address table plugin. Depending on the available rows in
     * the table, newly discovered addresses may replace old ones. The address
     * table plugin is enabled by default on the host. If you are using an SoC
     * platform, please be sure to add the address table plugin.
     *
     * When customers choose to send APS messages by using short addresses,
     * they should incorporate a retry mechanism and try again, no sooner than
     * 2 seconds later, to resend the APS message. If the app always
     * receives 0xBE (EMBER_IEEE_ADDR_DISCOVERY_IN_PROGRESS) after
