1. Overview#

==============

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

1.1 SDK#

===========

Version: NXP SDK next
Set up NXP SDK next generation environment.

1.2 Hardware requirements#

=============================

Micro USB cable
RD-RW612-BGA board
Personal Computer

1.3 Board settings#

======================

U38 DIP 1,2,3,4 all off HD12 1-2, 3-4 connected

2. Build and flash#

=====================

2.1 Build#

=============

flash_debug:

$ cd mcu-sdk-3.0
$ west build -b rdrw612bga examples/coex_examples/coex_wifi_peripheral_ht --toolchain armgcc --config=flash_debug -d coex_wifi_peripheral_ht

flash_release

$ cd mcu-sdk-3.0
$ west build -b rdrw612bga examples/coex_examples/coex_wifi_peripheral_ht --toolchain armgcc --config=flash_release -d coex_wifi_peripheral_ht

NOTE:

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

Find coex_wifi_peripheral_ht.elf/coex_wifi_peripheral_ht.bin in coex_wifi_peripheral_ht folder.

Only support armgcc to build coex application.

2.3 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_peripheral_ht.bin, 0x08000000

NOTE:

Monolithic feature is default enabled, this means it’s no need to flash binaries manually.

If disable Wi-Fi or BLE monolithic feature, download firmware manually.

SB firmware path: mcu-sdk-3.0/components/conn_fwloader/fw_bin

# CMD to write CPU1 wifi image to flash in J-link window:
J-Link> loadbin C:\xxx\rw61x_sb_wifi_a2.bin,0x08400000
# CMD to write CPU2 ble to flash in J-link window:
J-Link> loadbin C:\xxx\rw61x_sb_ble_a2.bin,0x08540000

3. Run#

3.1 Prepare the Demo#

========================

Connect a micro USB cable between the PC host and the MCU-Link USB port (J7) on the board.
Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
Download the program to the target board.
Launch the debugger in your IDE to begin running the example.

3.2 Running the example#

===========================

The log below shows the output of the coex examples (based on edgefast-shell) in the terminal window:

WiFi Test

Enter ‘w’ to enter Wi-Fi command mode. Enter ‘0’ to return coex menu.

Get the Wi-Fi driver and firmware version:

>
>wlan-version
wifi commands: wlan-version
WLAN Driver Version   : v1.3.r48.p37
WLAN Firmware Version : rw610w-V2, IMU, FP99, 18.99.6.p35, PVE_FIX 1

Get MAC Address:

>wlan-mac
wifi commands: wlan-mac

BLE Test

NOTE:

No need enter any BLE commands.

The demo does not require user interaction. The application will automatically start advertising the Health Thermometer Service and it will accept the first connection request it receives. If the peer subscribes to receive temperature indications, these will be sent every 1 second. The temperature readings are simulated with values between 20 and 25 degrees Celsius.

Low power manager test

Enter ‘p’ to enter pm command mode. Enter ‘0’ to return coex menu.

Only support enable command now.

>enable 3 3000

It may block serial port input.
