NRF9160 AssetTracker and NRFCloud MCELL

[crotberg]

Hello

We are using NRF9160 AssetTracker 1 and MQTT to AWS. We have a AWS Certificate, Root Certificate and Public and Private Keys on the device.

We want to start testing NRFCloud MCELL and wanted to know the simplest way to start testing without MQTT (We are going to add MQTT later)

How can we test the device with the Evaluation Key and REST API to start? 

Do we need to register the device on the NRFCloud with these Requests?

ProvisionDevices

RegisterPublicKeys

 

What is the minimal update we need to do to the device to be able to send Postman REST API requests?

Thank You

Hello Charlie

I was confused because we don't use Asset Tracker 2 yet, so you are saying I have to install that and test to be able to get the cell information manually from the log of the Asset Tracker V2 application.

Is there a way to get this information besides loading and testing Asset Tracker 2? We use Asset Tracker 1 now and don't plan on updating to 2 for a while as that requires changes to the backed code

I want to get this cell information and then try to do a Rest Locate from a PC to a device running Asset Tracker 1 to test the accuracy

Thank You

Hi Christopher,

1) Assert Tracker v1 cannot print such log file, but you should be able to get a single cell location from the LTE link monitor. We do not have a plan to update this application further.

2)You may realise that Assert Tracker( v1) has been removed since the NCS1.9.0 release because Assert Tracker v2 has been designed with better performance and advanced features for the similar application. I encourage you to switch to Assert Tracker v2, but it also does not use nRFcloud REST API right now. You need to refer nRF9160: nRF Cloud REST cellular positioning — nRF Connect SDK 2.0.0 documentation (nordicsemi.com) for how to use REST API for location service.

I think this kind of GPS accuracy test does not need to run PC+Assert Tracker v1 and this actually makes the test complex. You can just use nRF9160: nRF Cloud REST cellular positioning — nRF Connect SDK 2.0.0 documentation (nordicsemi.com) to do the test, and then you can compare its position output with "the real device position" you got from the map or other device. 

In summary, I think nRF9160: nRF Cloud REST cellular positioning — nRF Connect SDK 2.0.0 documentation (nordicsemi.com) is your best start point for nRFCloud cell location service with REST API.

Best regards,

Charlie
