Making the BLE (iBeacon mode) Connectable on a STM32WB55 Board: A Step-by-Step Guide

Advantages of iBeacon Mode

• Low power consumption, ideal for battery-powered devices
• Simple to implement and maintain
• Wide range of applications, including proximity sensing, indoor navigation, and more

Setting Up the Development Environment

TO BEGIN, ENSURE YOU HAVE THE STM32WB55 SDK PACKAGE INSTALLED AND CONFIGURED IN YOUR KEIL µVISION IDE:

1. Install the STM32WB55 SDK package from the official STMicroelectronics website.
2. Create a new project in KEIL µVision IDE and select the STM32WB55 as the target device.
3. Configure the project settings according to your needs (e.g., clock speed, peripherals, and compiler options).

Initializing the BLE Stack

INITIALIZING THE BLE STACK IS A CRUCIAL STEP IN ENABLING iBeacon MODE ON YOUR STM32WB55 BOARD:

#include "ble_stack_sdk.h"

int main(void) {
  // Initialize the BLE stack
  BLE_StackInit();

  // ...
}

This code snippet initializes the BLE stack, which is essential for enabling BLE functionality on your STM32WB55 board.

Configuring the BLE Advertising Parameters

TO CONFIGURE THE BLE ADVERTISING PARAMETERS, YOU’LL NEED TO DEFINE THE FOLLOWING:

• Advertising interval (i.e., the time between consecutive advertisements)
• Advertising timeout (i.e., the maximum time the device will advertise)
• iBeacon mode UUID (a unique identifier for your device)

#include "ble_adv.h"

int main(void) {
  // ...

  // Define advertising parameters
  ble_adv_params_t adv_params;
  adv_params.adv_intvl = 100; // Advertising interval (100ms)
  adv_params.adv_timeout = 30000; // Advertising timeout (30s)
  adv_params.uuid = UUID>iBeaconMode>; // iBeacon mode UUID

  // Set advertising parameters
  BLE_SetAdvParams(&adv_params);

  // ...
}

In this example, we define the advertising interval as 100 milliseconds and the advertising timeout as 30 seconds. We also specify the iBeacon mode UUID, which will be broadcasted by the device.

Starting the BLE Advertising

FINALLY, YOU NEED TO START THE BLE ADVERTISING PROCESS:

int main(void) {
  // ...

  // Start BLE advertising
  BLE_StartAdv();

  // ...
}

This code snippet starts the BLE advertising process, which will broadcast the iBeacon mode UUID to nearby devices.

Troubleshooting and Optimization

IF YOU ENCOUNTER ANY ISSUES OR EXPERIENCE PERFORMANCE ISSUES, TRY THE FOLLOWING:

• Verify that the BLE stack is properly initialized and configured.
• Check the advertising interval and timeout values to ensure they meet your requirements.
• Optimize power consumption by adjusting the advertising interval, transmission power, and device sleep modes.
• Use debugging tools, such as Serial Wire Output (SWO) or Logic Analyzer, to monitor and analyze BLE traffic.

By following these troubleshooting tips, you can optimize your BLE advertising performance and ensure reliable connectivity in iBeacon mode.
