Getting signal quality (TZ-754)

[acha666]

Question

Hi,

Is there a API to get the signal quality(maybe LQI or RSSI) of current connection?

Additional context.

No response

No, there isn't a single API specifically for obtaining the RSSI. However, the general command response (ESP_ZB_CORE_CMD_READ_ATTR_RESP_CB_ID, ESP_ZB_CORE_CMD_WRITE_ATTR_RESP_CB_ID) includes RSSI information. You can try sending a read or write attribute packet to the remote device; it will respond with the esp_zb_zcl_cmd_read_attr_resp_message_t, which contains the RSSI member.

Thank you. However, it seems that this method is for coordinator devices only. Could you advise how to get the signal quality in an end device application?

@acha666 ,

Why do you think this method can only be used in the coordinator? Is it because the coordinator does not include any cluster? I believe any device capable of sending read/write commands can use it to retrieve signal quality.

A related question: When I read the info.header.rssi value in the ESP_ZB_CORE_CMD_READ_ATTR_RESP_CB_ID callback handler on the coordinator side, the value is always 0 no matter the distance between the devices. Is there anything else I need to do to get the rssi value?
This is with SDK version 1.2.3 and IDF 5.1.3.

@simonborje, @acha666 ,

The issue has bee resolved in esp-zigbee-sdk v1.3.0, could you please update the version and test again?
