This example demonstrates how to use the X-NUCLEO-IDB05A1 component with one of the STM32 Nucleo platforms tested with the X-NUCLEO-IDB05A1 component to obtain heart rate information:

X-NUCLEO-IDB05A1 Datasheet

First, attach the X-NUCLEO-IDB05A1 to the STM32 Nucleo platform as shown here:

Steps:

1. Import Program3_BLEHeartRate to your online compiler.
2. Update the BLE_API library if it is outdated.
3. Compile the example with flag: -DIDB0XA1_D13_PATCH or add the line #define IDB0XA1_D13_PATCH to X_NUCLEO_IDB0XA1/x_nucleo_idb0xa1/x_nucleo_idb0xa1_targets.h
4. Remove all instances of LED1 in main.cpp as the shield’s LED is on the same line as SPI CLK which will prevent the board from working
5. Now press Compile. A file downloads (BLE_HeartRate_IDB0XA1_NUCLEO_F429ZI.bin).
6. Drag the file to the 'NODE_F429ZI' disk. The LED on the board will flash.
7. After flashing, hit the 'Reset' button to start the program.
8. Now open the BLE scanner on your phone. Start a scan.
9. Find your device; it should be named `bluenrg!`.
10. Click the connect to establish the connection with your device.
11. Click the Heart Rate Measurement. If you can see some notification from the device, congratulations!
