How to Make nRF52840 as Zigbee HA1.2 Coordinator

[uldara]

HI i want to use nRF52840 as Zigbee HA1.2 Coordinator, how to coding ? 

nRF52840 support this stack or not ?

Thank

Hi UL Dara, 

there is one, ultimately important point mentioned by Bjørn:

A Zigbee Home Automation device can join a Zigbee 3.0 Centralized Network that does not require a key exchange.

The key exchange is required in Nordic's coordinator example by default. I know this causes a lot of headaches, when you try to do some interoperability tests, but consider it as a security precaution.

There is an API to disable/enable this so-called compatibility mode. It can be called after ZB_BDB_SIGNAL_DEVICE_FISRT_START/REBOOT signals. For debug purposes, it may be wise to just call it inside zboss_signal_handler, upon reception of those signals.

I hope this helps . For further investigation of your case, you may try to post traffic dump from the failed attempt. There is a nrf52840-based sniffer available on github to do so.

Dear tomchy

Tanke for your reply

The code put like this right ?

and how to put requited key 

void zboss_signal_handler(zb_uint8_t param)
{
    /* Read signal description out of memory buffer. */
    zb_zdo_app_signal_type_t sig = zb_get_app_signal(param, NULL);
    zb_ret_t                 status = ZB_GET_APP_SIGNAL_STATUS(param);
    zb_ret_t                 zb_err_code;
    zb_bool_t                comm_status;

    switch(sig)
    {
        case ZB_BDB_SIGNAL_DEVICE_FIRST_START: // Device started and commissioned first time after NVRAM erase.
        case ZB_BDB_SIGNAL_DEVICE_REBOOT:      // BDB initialization completed after device reboot, use NVRAM contents during initialization. Device joined/rejoined and started.
           
            zb_bdb_set_legacy_device_support(0);
            if (status == RET_OK)
            {
                NRF_LOG_INFO("Device started OK. Start network steering.");
                bsp_board_led_on(ZIGBEE_NETWORK_STATE_LED);
                comm_status = bdb_start_top_level_commissioning(ZB_BDB_NETWORK_STEERING);
                ZB_COMM_STATUS_CHECK(comm_status);
            }
            else
            {
                NRF_LOG_ERROR("Device startup failed. Status: %d. Retry network formation after 1 second.", status);
                bsp_board_led_off(ZIGBEE_NETWORK_STATE_LED);
                zb_err_code = ZB_SCHEDULE_ALARM(bdb_restart_top_level_commissioning, 0, ZB_TIME_ONE_SECOND);
                ZB_ERROR_CHECK(zb_err_code);
            }
            break;

        case ZB_BDB_SIGNAL_STEERING:
            if (status == RET_OK)
            {
                /* Schedule an alarm to notify about the end of steering period */
                NRF_LOG_INFO("Network steering started");
                zb_err_code = ZB_SCHEDULE_ALARM(steering_finished, 0, ZB_TIME_ONE_SECOND * ZB_ZGP_DEFAULT_COMMISSIONING_WINDOW);
                ZB_ERROR_CHECK(zb_err_code);
            }
            else
            {
                NRF_LOG_INFO("Network steering failed to start. Status: %d. Retry network formation after 1 second.", status);
                bsp_board_led_off(ZIGBEE_NETWORK_STATE_LED);
                zb_err_code = ZB_SCHEDULE_ALARM(bdb_restart_top_level_commissioning, 0, ZB_TIME_ONE_SECOND);
                ZB_ERROR_CHECK(zb_err_code);
            }
            break;

        case ZB_ZDO_SIGNAL_PRODUCTION_CONFIG_READY:
            if (status != RET_OK)
            {
                NRF_LOG_WARNING("Production config is not present or invalid");
            }
            break;

        default:
            /* Unhandled signal. For more information see: zb_zdo_app_signal_type_e and zb_ret_e */
            NRF_LOG_INFO("Unhandled signal %d. Status: %d", sig, status);
            break;
    }

    /* All callbacks should either reuse or free passed buffers. If param == 0, the buffer is invalid (not passed) */
    if (param)
    {
        ZB_FREE_BUF_BY_REF(param);
    }
}

Thank

The key you posted appears to be the same used in the example, i.e. the one found in nRF5_SDK_for_Thread_and_Zigbee_v2.0.0\external\zboss\include\zb_config.h , on line 161.

/* 5.1.2.3.2 test specification - The default value for DUT-GPP being a Basic Combo pr a Basic Proxy
* is "ZigBeeAlliance09", i.e. {0x5A 0x69 0x67 0x42 0x65 0x65 0x41 0x6C 0x6C 0x69 0x61 0x6E
* 0x63 0x65 0x30 0x39}. */

Hi UL Dara, 

There should be no need to register a key. It should just work You code looks fine.

I would put the "zb_bdb_set_legacy_device_support(0);" a couple of lines further, after checking status to be RET_OK. That way, this code will be executed only if the coordinator is able to create a new Zigbee network.

What is the current status of your interoperability test? Were you able to add new devices using my advices?

Dear tomchy

i can add zigbee devices to Coordinator, but i didn't see and traffic from device.

i'm sure device connected with coordinator how to enable traffic log ?

Thanks
