Hello again, Luca

[quote user="Luca Z"]Thanks for your reply.[/quote]

No problem at all, I am happy to help!

[quote user="Luca Z"]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 ?[/quote]

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.

[quote user="Luca Z"]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.[/quote]

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,
Karl

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,

Hello Luca Zambalas,

Thank you for your patience with this.

[quote user=""]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 ?).[/quote]

This does unfortunately indeed depend on the sim card you have, and the network operators in the region, and short of buying a different sim / plan there is not all that much that could be done about it. I've seen other forum-goers express frustration with this in the past as well.

[quote user=""]1. Is it possible to add a graph on nRF Connect Cloud for a new dataset (e.g air pressure, aire quality, color)[/quote]

The nRF Cloud does have cards for displaying GPS, TEMP, HUMID, AIR_PRESS, FLIP, and RSRP. So for example if you would like to add the air pressure, you would need to add .air_pressure = true to the service info ui struct here.
If you want to start sending air pressure to nRF Cloud, the JSON protocol format is described in this Github repository; https://github.com/nRFCloud/application-protocols/tree/v1/schemas/deviceToCloud

[quote user=""]If yes how to proceed ? Is the graph generated automatically from the JSON messages when received on the Cloud ?[/quote]

Unfortunately, you can not add graphs for data that is not GPS, TEMP, AIR_PRESS, FLIP and RSRP currently. Incoming JSON messages are parsed and displayed on their respective graph. Unsupported AppIds can still be sent but will only show data in the terminal.

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 ?

[/quote]

I talked to the developers about this, and they told me that since the Asset Tracker v2 is primarily made to demonstrate the asset tracker use-case and functionality, it does not include use of the accelerometer, air pressure, quality and color data.

Best regards,
Karl
