NXP M.2 Wi-Fi and BT Shield

Overview

This Zephyr shield is tested with the following M.2 modules and hardware for Wi-Fi and Bluetooth applications:

• Embedded Artist 1XK module - uses Murata 1XK radio module with NXP IW416 chipset

• Embedded Artist 2EL module - uses Murata 2EL radio module with NXP IW612 chipset

More information about supported chipsets, radio modules and M.2 modules can be found in below links,

• IW612 NXP Chipset

• IW416 NXP Chipset

• 2EL Murata Radio Module

• 1XK Murata Radio Module

• 1XK Embedded Artist Module

• 2EL Embedded Artist Module

Requirements

To use the shield, below requirements needs to be satisfied.

• M.2 module with BT HCI UART and SDIO Interface with NXP IW416 or IW612 SoC support.

• Host platform shall have compatible M.2 interface slot.

• For Coex (Wi-Fi + BT), UART driver that supports UART RTS line control to wakeup BT CPU from sleep.

• To use default Bluetooth-Shell app it needs ~490KB flash & ~130KB RAM memory.

• To use default Wi-Fi-Shell app it needs ~1MB flash & ~1.2MB RAM memory.

Integration Platform

This shield works with below host platform,

• MIMXRT1060-EVK Rev-C.

Fetch Binary Blobs

To support Bluetooth or Wi-Fi, nxp_m2_wifi_bt requires fetching binary blobs, using the following command:

west blobs fetch hal_nxp

Programming

Below are the supported shields to be used with --shield <option> when you invoke west build.

• nxp_m2_1xk_wifi_bt: For Wi-Fi/Bluetooth samples to work with NXP IW416 SoC

• nxp_m2_2el_wifi_bt: For Wi-Fi/Bluetooth samples to work with NXP IW612 SoC

For example:

# From the root of the zephyr repository
west build -b mimxrt1060_evk@C//qspi --shield nxp_m2_1xk_wifi_bt samples/bluetooth/handsfree

# From the root of the zephyr repository
west build -b mimxrt1060_evk@C//qspi --shield nxp_m2_2el_wifi_bt samples/net/wifi/shell
