Adding new data in Asset Tracker V2 app and generate new graph on nRF Connect Cloud

[Luca Z]

Hello,

I recently got my hands on a Nordic Thingy:91. I got it registered to nRF Connect Cloud, SIM activated (iBasis sent me a new one since original didn't work. See https://devzone.nordicsemi.com/f/nordic-q-a/79384/nordic-thingy-91---can-t-connect-to-nrf-cloud), flashed the following :

- nRF9160 modem with version 1.3.0 (latest available on NordicSemi.com)

- nRF9160 app with asset tracker V2 (thingy91_asset_tracker_v2_ltem_2021-06-28_7a076c22.hex)

- nRF5280 with connectivity brdige (thingy91_nrf52_connectivity_bridge_2021-06-28_7a076c22.hex)

Thingy91 boots, after several minutes I can see Temperature and Humidity data on nRF Connect Cloud web interface. No GPS, no air pressure, no air quality, no color data.

 

After some research on NordicSemi devzone I realized GPS depends on PSM mode of the modem. Unfortunately in France no operator supports PSM so I can forget GPS features... (Maybe we can make it work independently from PSM with some hw/fw rework ?).

After some digging in the code I noticed in the Asset Tracker V2 app only Temperature & Humidity data are sampled and published to the cloud. I see both BME680 and BH1749 drivers can be found in nRF Connect SDK. I will make the changes in the Asset Tracker V2 app to add air pressure, quality and color data.

My question is :
1. Is it possible to add a graph on nRF Connect Cloud for a new dataset (e.g air pressure, aire quality, color) ? If yes how to proceed ? Is the graph generated automatically from the JSON messages when received on the Cloud ?

I also have questions regarding Asset Tracker v2 app :

2. Why aren't air pressure, quality, color data used in Asset Tracker V2 app ?

3. Why is the High G accelerometer (ADXL372) not used ?

Thanks in advance.

Hi Karl,

Thanks for your reply.

It's quite a pity that Air quality and Color cards have not yet been implemented in nRF Cloud. Furthermore that users can't create custom cards. What is Nordic's roadmap regarding nRF Cloud development ? Will they develop this feature ?

Thanks for the guidlines regarding Air pressure and Flip. I have now AIR_PRESS data displaying on nRF Cloud. Next I'll look into FLIP data.

Best regards,

Luca

Unfortunately, we do not discuss roadmaps and/or future releases here on DevZone, so I would have to ask that you make such inquiries directly to your Regional Sales Manager (RSM).
If you do not know who your RSM is you can send me a direct message with your location so that I may provide you their contact information.

Great, I'm glad to hear that you got air pressure data up and running as expected.

Please do not hesitate to ask if you should encounter any other issues or questions!

Best regards,
