BLE Stack or Example for iMXRT1064 + IW612 using FreeRTOS

Hi everyone,

I’m working on a custom board powered by the i.MX RT1064. The firmware is written in C and runs FreeRTOS with LwIP already integrated.

I’ve successfully tested the Wi-Fi HTTP server example from the MCUXpresso SDK using the MIMXRT1064-EVK and a IW612 module — It works.

Now I’d like to test BLE communication, but I haven’t found any sample code or a compatible BLE stack that works with the RT1064 and IW612 over UART/HCI.

Does anyone know if there’s an example or a lightweight BLE stack that can be integrated into a FreeRTOS project for BLE peripheral functionality?

Thanks in advance for any pointers!

Please see the below AN for reference.

UM11441: Getting Started with NXP-based Wireless Modules on i.MX RT Platforms Running FreeRTOS[UM11441]

as well as this guide (section 5 Bluetooth Classic/Low Energy Applications).

Hi,
I just wanted to add that I was able to get the peripheral HT example working on the MIMXRT1064 by following the guides:
Migrate examples from RT1060EVK to RT1064
and UM11442.
I modified the peripheral HT sample from:
SDK_25_06_00_MIMXRT1060-EVKC\boards\evkcmimxrt1060\edgefast_bluetooth_examples\peripheral_ht\

But I had to use the file sduart_nw61x_v1.bin.se in nw61x_cpu12_se.c:

const uint8_t fw_cpu12[] = {
//#include <sduart_nw61x.bin.se.inc>
 #include <sduart_nw61x_v1.bin.se.inc>
};

The binary file should be converted to hexadecimal strings with https://tomeko.net/online_tools/file_to_hex.php?lang=en
and add .inc extension.

I used the ublox EVK-MAYA-W271.

Enjoy!
