Broadcaster

Overview

This example demonstrates how to utilize the broadcasting function of BLE. After the program is executed, it periodically sends out non-connectable advertisements. The content of these advertisement packets includes the name WM BROADCASTER and a manufacturer-specific field. Each time an advertisement is broadcast, the counter in the manufacturer-specific field increments by 1. The counter is 1 Byte in size, meaning that once the count reaches 255, it will roll back to 0.

Requirements

  • A board with BLE support

  • nRF Connect APP
