Hi @MNNgyn ,
Thanks for your interest in NXP MIMXRT series!
The Edgefast BT project for the RT1170 is built on FreeRTOS, which for some historical reasons is currently the most widely supported RTOS in NXP's SDK. Additionally, some AzureRTOS examples are provided for users to learn from and use.
Howerver there is no clear guidance document on how to migrate from FreeRTOS to AzureRTOS. There are some documents about AzureRTOS in the SDK that may be helpful for you to understand it, you can find them here:SDK_2_15_000_MIMXRT1170-EVK\docs\AzureRTOS
Sorry for any inconvenience, and you're welcome to raise specific needs and considerations that require such a migration, and we'll help you get the voice of the customer back internally.
Best regards,
Gavin
