Hello community! We are trying to send AT commands through UART (using FreeRTOS) to a BT module, based on the interrupts example provided. Our issue is that the program never enters the handler when it comes to receiving the responses. Does anyone have any insight?

Sorry, but there is so little information in your post, especially as we don’t provide an I.MX7 demo ourselves, and you seem to be asking about a hardware configuration issue rather than a FreeRTOS issue, that we couldn’t even begin to suggest anything other than looking at the UART and interrupt controller sections in the hardware manual. https://www.freertos.org/FAQ-how-to-use-the-FreeRTOS-support-forum.html
