nRF Cloud - Signal Strength Indicator

[napei_]

Hi,

I have an nrf9160 on a custom board connected successfully to nRF cloud and i'm pushing data into it. I send the modem info to the device shadow, and also send RSRP messages like below once every few minutes. 

{
  "messageType": "DATA",
  "data": "-96",
  "appId": "RSRP",
  "ts": 1678416372978
}

But, I can't see the device's signal strength in the nRF Cloud device managemenet page, it just shows up as N/A. 

The device is making cellular positioning requests with both MCELL and SCELL and will also use GNSS at times, along with A-GPS and P-GPS. For other data, I'm following these schemas: https://github.com/nRFCloud/application-protocols/tree/v1/schemas/deviceToCloud 

What other data do I need to be sending for signal strength to be showing up?

Hello napei_ ,

Could you please elaborate more on your setup? What version of nRF Connect SDK are you using? 

Are you able to update other information?

Kind regards,
Øyvind

It's an nrf9160 on a custom PCB, connected to LTE-M1.

Using the latest 2.3.0 SDK, with firmware that is based on asset tracker but built from scratch with some modifications.

I can update all other information normally. I'm sending JSON arrays to the /batch endpoint manually just fine, sending appIds of TEMP, HUMIDITY, AIR_PRESS, GNSS, RSRP, and a custom BATTERY one, all of which are showing up fine on the UI. It's also making its own cellular location requests, which is sending multi-cell RSRP values just fine. I am also manually retrieving RSRP and sending it along with sensor data which is showing up in the UI.

I am updating the device shadow with nrf_cloud_shadow_device_status_update on initial connection, with the modem_param_info struct populated by the SDK. I can't find any documentation on the UI elements, particularly that little signal strength indicator. I assume it's supposed to function, as you can sort devices by their signal strength.

Let me know if you need any more info.

Thanks for providing this information. I have forwarded to our nRF Cloud team and hope to have an answer by end of today, beginning of next week. 

Kind regards,
Øyvind

Thanks Øyvind, I'll wait for the fix and update if it's fixed for me

Hi Øyvind 

Just checking if this was supposed to be fixed in the latest round of downtime we had, as I'm not seeing any change. If not then all good, just thought I'd check.

 napei_ , sorry for the late reply. I was at Embedded World last week. 

Not sure when the fix will be deployed, but from what I can tell it should be right around the corner. If you haven't seen a solution within the next couple of days, let me know and I will contact our team. 

Kind regards,
Øyvind
