Inquiry on Publishing Data to ThingSpeak via MQTT Using Zephyr

[Amank0623]

Dear DevZone Support,

I hope this message finds you well. I'm currently working on a project where I've successfully been publishing data to AWS IoT Core utilizing the functionalities supported by AWS. Now, I'm exploring the possibility of publishing data to ThingSpeak via MQTT using Zephyr.

Could you please provide guidance or point me in the right direction on how to accomplish this task? Specifically, I'm interested in understanding the necessary steps, configurations, and any code examples or resources available that could assist me in integrating Zephyr with ThingSpeak's MQTT interface for data publishing.

Your expertise and assistance in this matter would be greatly appreciated.

Thank you in advance for your time and support.

Warm regards, Aman

Hello,

what board are you using?

[Amank0623]

nRF 53400 with gsm ec200u

[Hakon]

Then I would imagine you can just use one of the Zephyr networking samples like this one zephyr\samples\net\mqtt_publisher. Have you tried that?

[Amank0623]

That's  good, but i want to publish data with the help of Gsm ec200u module then how should i go....

[Hakon]

You need to make sure you can get the Zephyr network stack working with the ec200u modem. Then use the Zephyr MQTT library to connect to the broker. I thought you had already made sure this when you said that you had made the interface between the nrf53 and the modem.

yes, actually we are able to send data into AWS just i want to switch it with ThingSpeak. i need thingspeak libraries for zephyr

Hi!

Håkon is out of office, so I'm replying instead.

I'm not aware of any thingspeak libraries for zephyr. So likely you would need to implement this yourself. But I suggest checking with the Zephyr community on Discord, and see if anyone there have experience with thingspeak for Zephyr.
