Azure IoT Hub Sample on Thingy91

[Neso]

Is there any guides or easy way to make the Azure IoT Sample work with the Thingy91 or e.g. Icarus IoT v2?

Hello, and thanks for providing. Not sure why you are not able to upload files etc. but I did get the file through Google Drive. 

Looking at the documentation of Azure IoT hub, the sample does not support Thingy:91. 

Looking at the log provided it does state:

C:/Users/neshe/nRF/azure_iot_hub/src/main.c:202: undefined reference to `boot_write_img_confirmed', and I'm able to reproduce. Will need to discuss internally.

The closest I have to any kind of documentation for getting this to work is through e.g. https://purple.telstra.com/blog/device-authentication-with-nordic-thingy-91-and-azure-iot-hub

Kind regards,
Øyvind

Thanks for looking into this. Yes, I saw it was't supported in the sample, but I need to get it working with other nrf boards for it to be something we can use. What's the main reason it's so hard to get working on other boards?

Have inquired internally, no feedback yet. Hope to have an answer by end of this week.

In order for boot_write_img_confirmed() to be compiled in, you need to enable CONFIG_MCUBOOT_IMG_MANAGER=y

Since the Thingy:91 is not officially supported in this sample, that needs to be done manually.

In general, you need to ensure that required options are enabled when adding support for a new board to an application. In this case, the following are needed from nrf9151dk_nrf9151_ns, i.e:

CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_AZURE_FOTA=y
CONFIG_FOTA_DOWNLOAD=y
CONFIG_DFU_TARGET=y
CONFIG_MCUBOOT_IMG_MANAGER=y
CONFIG_IMG_MANAGER=y
CONFIG_STREAM_FLASH=y
CONFIG_FLASH_MAP=y
CONFIG_FLASH=y
CONFIG_IMG_ERASE_PROGRESSIVELY=y
CONFIG_DOWNLOAD_CLIENT=y
CONFIG_DOWNLOAD_CLIENT_STACK_SIZE=4096
