RE: How to Retrieve LQI for End Devices Connected via a Router in a Zigbee Network?

So from your coordinator's application, you should do something like:

void read_lqi_request()
{
zb_bufid_t buf = zb_buf_get_out();
zb_zdo_mgmt_lqi_param_t *req_param = ZB_BUF_GET_PARAM(buf, zb_zdo_mgmt_lqi_param_t);

req_param->start_index = 0;
req_param->dst_addr = <ADDRESS>; // End device's short address. <--- This line

zb_uint8_t tsn = zb_zdo_mgmt_lqi_req(buf, get_lqi_cb);

if (tsn == RET_OK)
{
TRACE_MSG(TRACE_APS1, "LQI request sent successfully", (FMT__0));
}
else
{
TRACE_MSG(TRACE_ERROR, "Failed to send LQI request", (FMT__0));
}
}

void get_lqi_cb(zb_uint8_t param)
{
zb_bufid_t buf = param;
zb_uint8_t *zdp_cmd = zb_buf_begin(buf);
zb_zdo_mgmt_lqi_resp_t *resp = (zb_zdo_mgmt_lqi_resp_t *)(zdp_cmd);
zb_zdo_neighbor_table_record_t *record = (zb_zdo_neighbor_table_record_t *)(resp + 1);
zb_uint_t i;

printf("LQI Callback: status=%d, neighbor_table_entries=%d, start_index=%d, neighbor_table_list_count=%d\n",
resp->status, resp->neighbor_table_entries, resp->start_index, resp->neighbor_table_list_count);

for (i = 0; i < resp->neighbor_table_list_count; i++)
{
printf("Network Addr=%d, Dev Type=%d, RxOnWhenIdle=%d, Relationship=%d, PermitJoin=%d, Depth=%d, LQI=%d\n",
record->network_addr,
ZB_ZDO_RECORD_GET_DEVICE_TYPE(record->type_flags),
ZB_ZDO_RECORD_GET_RX_ON_WHEN_IDLE(record->type_flags),
ZB_ZDO_RECORD_GET_RELATIONSHIP(record->type_flags),
record->permit_join, record->depth, record->lqi);

record++;
}
}

It is your own implementation, but you need to call it from the coordinator, and use the end device's address as the destination address.

Hi,

I want to receive end device LQI using coordinator even if the end device is connected through router

Hello,

It looks like you are trying to get the LQI of the coordinator from the end device? Are you sure you don't want to do it the other way around? The end device is not aware of the different nodes in the network, other than it's parent, if it is not a router itself. So I believe you should try to measure the LQI of the end device from the coordinator.

Best regards,

Edvin
