coex_wifi_a2dp_sink

coex_wifi_a2dp_sink#

Overview#

The example demonstrates the coexistence of Bluetooth A2DP sink (edgefast_open) and Wi-Fi.

This document provides step-by-step procedures to build and test the example, and also instructions for running the included sample applications.

Supported Boards#

MIMXRT1060-EVKC + IW416
Overview

This document provides step-by-step procedures to build and test coex examples, and also instructions for running the included sample applications.

Hardware requirements

  • Micro USB cable

  • evkcmimxrt1060 board

  • Personal Computer

  • One of the following modules:

    • Embedded Artists 2EL M.2 Module (Rev-A1) - direct M2 connection

    • Embedded Artists 1ZM M.2 Module (EAR00364) - direct M2 connection

    • Embedded Artists 1XK M.2 Module (EAR00385) - direct M2 connection

Board settings

Before building the example application define Wi-Fi module in the _boards/evkcmimxrt1060/coex_examples/coex_wifi_a2dp_sink/prj.conf.

If you want to use Embedded Artists 2EL M.2 Module (Rev-A1), please set CONFIG_MCUX_COMPONENT_component.wifi_bt_module.board_murata_2el_m2 to y.

CONFIG_MCUX_COMPONENT_component.wifi_bt_module.IW61X=y CONFIG_MCUX_COMPONENT_component.wifi_bt_module.board_murata_2el_m2=y

If you want to use Embedded Artists 1ZM M.2 Module (EAR00364), please set CONFIG_MCUX_COMPONENT_component.wifi_bt_module.board_murata_1zm_m2 to y.

CONFIG_MCUX_COMPONENT_component.wifi_bt_module.88W8987=y CONFIG_MCUX_COMPONENT_component.wifi_bt_module.board_murata_1zm_m2=y

If you want to use Embedded Artists 1XK M.2 Module (EAR00385), please set CONFIG_MCUX_COMPONENT_component.wifi_bt_module.board_murata_1xk_m2 to y.

CONFIG_MCUX_COMPONENT_component.wifi_bt_module.IW416=y CONFIG_MCUX_COMPONENT_component.wifi_bt_module.board_murata_1xk_m2=y

Jumper settings for RT1060-EVKC (enables external 5V supply):

remove J40 5-6 connect J40 1-2 connect J45 with external power(controlled by SW6)

Embedded Artists 2EL module datasheet: https://www.embeddedartists.com/doc/ds/2EL_M2_Datasheet.pdf Embedded Artists 1ZM module datasheet: https://www.embeddedartists.com/doc/ds/1ZM_M2_Datasheet.pdf Embedded Artists 1XK module datasheet: https://www.embeddedartists.com/doc/ds/1XK_M2_Datasheet.pdf

The hardware should be reworked according to the hardware rework guide for evkcmimxrt1060 and Murata 1XK/1ZM/2EL M.2 Adapter in document Hardware Rework Guide for EdgeFast BT PAL.

NOTE:

  1. To ensure that the LITTLEFS flash region has been cleaned, all flash sectors need to be erased before downloading example code.

  2. After downloaded binary into qspiflash and boot from qspiflash directly, please reset the board by pressing SW7 or power off and on the board to run the application.

Build and flash

Prerequisites:

  • CMake (version >=3.24)

  • Ninja (version >=1.12)

  • ARM GCC Toolchain (only support ARM GCC)

  • Python3 (version >=3.6)

NOTE: Make sure that the paths of all these tools are set into the path system variable.

2. Building

flexspi_nor_debug:

$ cd <sdk root>
$ west build -b evkcmimxrt1060 examples/coex_examples/coex_wifi_a2dp_sink --toolchain armgcc --config flexspi_nor_debug -d coex_wifi_a2dp_sink

flexspi_nor_release:

$ cd <sdk root>
$ west build -b evkcmimxrt1060 examples/coex_examples/coex_wifi_a2dp_sink --toolchain armgcc --config flexspi_nor_release -d coex_wifi_a2dp_sink

NOTE:

  1. -d coex_wifi_a2dp_sink -> Specify the generated project path. Can name it as needed.

  2. Find coex_wifi_central_ht.elf/coex_wifi_central_ht.bin in coex_wifi_central_ht folder.

  3. Only support armgcc to build coex application.

  4. CSI and NET_MONITOR are disabled by default due to RAM limitation. If to test CSI and NET_MONITOR, enable them and disable enterprise in wifi_config.h. Modify middleware/wireless/coex/src/configs//wifi/wifi_config.h: Enable CSI and NET_MONITOR: #define CONFIG_CSI 1 #define CONFIG_NET_MONITOR 1 Disable enterprise: #define CONFIG_WPA_SUPP_CRYPTO_ENTERPRISE 0 #define CONFIG_WPA_SUPP_CRYPTO_AP_ENTERPRISE 0

4. Flash Binaries

Flash the image with the following command,

##### CMD to write CPU3 coex app image to flash in J-link window:
J-Link> loadbin C:\xxx\coex_wifi_a2dp_sink.bin, 0x60000000
Run
Prepare the Demo

  1. Connect a micro USB cable between the PC host and the MCU-Link USB port (J53) on the board.

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Launch the debugger in your IDE to begin running the example.
