End User GUI development

[Sajid]

Hey so I am making a capstone project with Drapers lab from University of Massachusetts Lowell and one of the requirements is to create an friendly end-user GUI instead of the nRF Cloud. So as a solution I was thinking of using a progressive Web App (PWA) but the problem I am having is that I need to take data from the Nordic web server and I am not sure how to code this for the nRF 9160. Could someone help me in how to do this? Any links, documentation or code examples. Thank you.

Hi,

Thanks for reaching out with this request. Based on your description, you are essentially building your own cloud service, so what you need is an API to interface with nRF Cloud.

Please refer to the Overview of the nRF Cloud APIs and explore the nRF Cloud REST API here: https://docs.nordicsemi.com/bundle/nrf-cloud/page/APIs/APIOverview.html#nrf-cloud-rest-api.

You can test the REST APIs using tools like Postman before integrating them into your cloud service application.

Best regards,

Charlie

Hey Charlie,

Thank you for your response and for sharing the nRF Cloud API documentation. I appreciate the guidance.

I wanted to ask if you could provide some insight into how to use the nRF Cloud REST API effectively. Specifically:

1. What are the key steps to integrate it with an external cloud service like Firebase?
2. Would this require extensive coding, or are there tools that simplify the process?

I plan to use the API to retrieve temperature, humidity, and GPS data from the Nordic server and store it in Firebase for easy access on my phone. Any recommendations or examples would be greatly appreciated.

Looking forward to your advice.

Hi Sajid,

Unfortunately, we cannot provide further assistance with your custom cloud integration using the nRF Cloud REST API.

The nRF Cloud REST API follows standard REST API principles and is compatible with any custom cloud service that supports HTTP communication. As long as you have expertise in your cloud service, the integration should be fairly straightforward.

Please follow the documentation I mentioned earlier, and feel free to reach out if you encounter any specific issues during your implementation.

Best regards,
Charlie

Dear Charlie,

Thank you for your response. We have updated our approach and now plan to use the terminal on nRF Cloud to allow the user to change the temperature and humidity thresholds in the code.

Could you provide any documentation or resources on how to use the nRF Cloud terminal for this purpose? Any guidance on configuring and sending commands through the terminal would be very helpful.

Looking forward to your advice.

Best regards,

Sajid Hossain.

Hi Sajid,

The message schema for bidirectional communication between nRF Cloud and the device can be found in the following repository.

nRFCloud/application-protocols: Contains the application protocol definition for long-range devices connecting to nRF Cloud

You can find some pritical usage from following disucssion:
(+) Sending commands from nrfcloud terminal to LTE Device - Nordic Q&A - Nordic DevZone - Nordic DevZone
(+) message from the nRF Cloud terminal to asset_tracker - Nordic Q&A - Nordic DevZone - Nordic DevZone
(+) How to receive data from nRF cloud to LTE device - Nordic Q&A - Nordic DevZone - Nordic DevZone

Best regards,
