Getting zigbee device RSSI/LQI value of all network device

Hello,

[quote user="dhavaldalvadi"]I found the standard ZigBee device which I am using is smart plug
I found from the answer you suggested it returns as router[/quote]

Great!

[quote user="dhavaldalvadi"]Is it possible device can be in router and also have application like smart bulb or plug in ZigBee?[/quote]

Yes. In fact the ZigBee Light Bulb sample in nRF Connect SDK is configured as a router by default.

The role is configured in a configuration file (.conf) by setting one of the choices for CONFIG_ZIGBEE_ROLE: CONFIG_ZIGBEE_ROLE_END_DEVICE, CONFIG_ZIGBEE_ROLE_ROUTER or CONFIG_ZIGBEE_ROLE_COORDINATOR.

Best regards,

Maria

Hi Maria

Is it possible device can be in router and also have application like smart bulb or plug in ZigBee?

Hello,

Great to see that you were able to find out how to get the LQI values with zb_zdo_mgmt_lqi_resp_t.

[quote user="dhavaldalvadi"]Its not able to know if its router or end device both gives similar value most of the cases[/quote]

The zb_zdo_neighbor_table_record_s struct does not have a device_type parameter directly, so you need to go through the type_flags parameter and get the device_type with ZDO_RECORD_GET_DEVICE_TYPE like this:

zb_uint8_t device_type = ZB_ZDO_RECORD_GET_DEVICE_TYPE(record->type_flags);

Best regards,

Maria
