Hi,
I am trying to use the thingy91 to publish some sensor data to an Azure IoT Hub, I've tried to look at mqtt_simple and modified "asset_tracker" application but I couldn't succeed.
so is there any example showing how to publish data to Azure IoT Hub (MQTT broker) using thingy91?
Thank you in advance...
Hello,
Can you provide some more information on what is failing? Are you able to connect the server? Do you get any errors?
We have an unofficial example project called Bifravst which will connect the Thingy:91 to Azure. This is however work in progress, and I urge to read through what is documented.
Kind regards,
Øyvind
You may also want to look at this github PR which will be part of NCS 1.4.0, when that is released.

Deri said:I have to run the flash twice to program my device properly. any suggestions to solve this issue?
Can you try running west flash --erase?
Deri said:It is the same build image that has been flashed on two devices (Thingy91) and the same SIM card, please look at the log files of both devices to figure out why does it show this error message?
I will need some more time to look into this case. Have you tried an unmodified version of the Azure IoT Hub sample on both? Only adding relevant information to connect?

Excellent!

Have you run west update after doing git pull?
I have succeeded to compile my code after running #west update , but I got an error to connect to Azure IoT hub:
Please look at the log file.

Is there any update about my case using the "Azure IoT Hub sample"? are there missing configurations should I add to prj_thingy91_nrf9160ns.conf? I got the same results using both devices of Thingy91.

Looks like you still have an issue with your certificates, often giving -95 (EOPNOTSUPP).
#define EOPNOTSUPP 95 /* Operation not supported on transport endpoint */
Have you added the certificates correctly to nrf\samples\nrf9160\azure_iot_hub\certs\certificates.h?
yes, Please look at certificates.h
