FRDM-RW612 external accelerometer sensor over BLE

This demo shows how to use a FXLS8974CF accelerometer connected to the FRDM-RW612's MikroE port. Also, accelerometer measurements are sent over Bluetooth low energy so they can be seen with the IoT toolbox mobile application.

2. Hardware

ACCEL 4 CLICK (FXLS8974CF)

ACCEL 4 CLICK configuration:

No special configuration required simply connect into the FRDM-RW612 mikroBUS header, use the GND pins as reference.

FRDM RW612 Board

3. Setup

Connect the accel 4 click board in the mikroBUS header of the FRDM-RW612 Board

Connect the FRDM-RW612 board with a USB C cable on the MCU Link Connector to your computer

The BLE firmware is flashed together with the application since it has the monolithic configuration activated.

IoT Toolbox app

On your phone download the IoT Toolbox app

---

How to run:

1. Use MCUXpresso IDE to flash the application.
   
2. Open the IoT Toolbox app on your phone.
3. Run the demo.
4. on the IoT Toolbox app select "Wireless UART"
5. Connect to "WU_Accelerometer_Sensor"
6. The accelerometer data will appear periodically on the app.

4. Results

Once the demo is running properly and you setup your phone with bluetooth and the IoT Toolbox app on the right Wireless UART you should see the next screen:
