Hi.


How can I send a LQI ​​request to the coordinator?
This code does not request anything. No response is received.

// dstAddr = 0x0000, startIndex = 0

void send_mgmt_lqi_req(u16 dstAddr, u8 startIndex)

{

    u8 buf[8];

    buf[0] = startIndex; // StartIndex



    printf("Sent Mgmt_LQI_req to 0x%04x with startIndex = %d\r\n", dstAddr, startIndex);



    if(zb_isDeviceJoinedNwk()) {





        epInfo_t dstEpInfo;

        TL_SETSTRUCTCONTENT(dstEpInfo, 0);



        dstEpInfo.profileId = ZDO_PROFILE_ID; //HA_PROFILE_ID;

        dstEpInfo.dstAddrMode = APS_SHORT_DSTADDR_WITHEP;

        dstEpInfo.dstEp = APP_ENDPOINT1;

        dstEpInfo.dstAddr.shortAddr = dstAddr;





        uint8_t apsCnt = 0;

        u8 ret = af_dataSend(APP_ENDPOINT1, &dstEpInfo, MGMT_LQI_REQ_CLID, 1, buf, &apsCnt);



        printf("af_dataSend ret: %d\r\n", ret);

    }

}

How to do this correctly?


Thanks.

I am not sure that it is it, but do you have correct EP of the coordinator?
You have:

1. dstEpInfo.dstEp = APP_ENDPOINT1;

复制代码

And your source ep is:

1. af_dataSend(APP_ENDPOINT1,

Hi.

I want to get the signal level of my device (LQI).

1.     int8_t rssi = ZB_RADIO_RSSI_GET();
   
2.     ZB_RADIO_RSSI_TO_LQI(0, rssi, lqi);
   

复制代码

ZB_RADIO_RSSI_GET always returns a value around -100.

I would like to request LQI from the coordinator.

This code does it.

1. static uint8_t lqi = 0;
   
2. static bool lqi_true = false;
   
3. static uint8_t t_index = 0;
   
4. 
   
5. static void start_lqi_scan(uint8_t idx);

11. 
    
12.     uint8_t n_tbl_cnt = rsp->neighbor_tbl_lst_cnt;
    
13. 
    
14.     uint16_t src_addr = zb_getLocalShortAddr();
    
15. 
    
16.     for (uint8_t i = 0; i < n_tbl_cnt; i++) {
    
17.         if (src_addr == rsp->neighbor_tbl_lst[i].network_addr) {
    
18.             lqi = rsp->neighbor_tbl_lst[i].lqi;
    
19.             lqi_true = true;
    
20.             t_index = rsp->start_index;
