Did you also follow the provisioning steps?

yes, Please look at certificates.h

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?

Hi,

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.

I have succeeded to compile my code after running #west update , but I got an error to connect to Azure IoT hub:

Can you try running west flash --erase?

[quote user="Tarek_Deri"]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?[/quote]

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?

Hi,

1-I need to run #west flash twice to flash the build successfully: Assum the Thingy91 has been flashed with an asset tracker application or any other image, after that, I've compiled my simple MQTT code using:
#west build -b thingy91_nrf9160ns -d build

then I run the flash command at first time #west flash,I noticed that Thingy91 gets stuck(not able to boot) and there is no data showing on the terminal (puTTY ), I've tried to resetThingy91 several times (power off-on) with no response.

so every time I have to run the flash twice to program my device properly. any suggestions to solve this issue?

2-The first device "Thingy91" works properly on one Thingy91 and showing "ERROR: mqtt_connect -95" on another device:

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?

Hello,

[quote user="Tarek_Deri"]sorry for late replay, I was reading and learning how to use Zephyr API and kernel services to communicate with peripherals.[/quote]

No worries, fully understand the prioritization.

[quote user="Tarek_Deri"]1-I need to run #west flash twice to flash the build successfully.[/quote]

Can you elaborate? Are you getting an error?

[quote user="Tarek_Deri"]2-The first device "Thingy91" works properly and send data to Azure when pressing the button , while the other one showing an error "ERROR: mqtt_connect -95" , I've tried to update the FW of modem and debug this issue by AT commands, but still didn't figure out how to solve it. I've attached a log file for this issue. [/quote]

error -95 is often seen when there is an issue with the certificates. Have followed the steps for Prerequisites for connecting to Azure IoT Hub and Provisioning of the certificates?

Thanks!

RE: Thingy:91 + Azure IoT Hub

Deri — Mon, 05 Oct 2020 23:07:33 GMT

Hi,
sorry for late replay, I was reading and learning how to use Zephyr API and kernel services to communicate with peripherals.
I've modified the simple MQTT sample to publish the temperature, the humidity of the sensor to Azure IoT Hub, I am using j-link to flash Thingy91 and VScode with cmd terminal to compile and flash my code.

I've used "MQTT_TRANSPORT_NON_SECURE" and I tested the compiled code on two devices "Thingy91", I am facing two issues:

1-I need to run #west flash twice to flash the build successfully.

2-The first device "Thingy91" works properly and send data to Azure when pressing the button , while the other one showing an error "ERROR: mqtt_connect -95" , I've tried to update the FW of modem and debug this issue by AT commands, but still didn't figure out how to solve it. I've attached a log file for this issue.

You may also want to look at this github PR which will be part of NCS 1.4.0, when that is released.

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
