Module bluetooth 

Bluetooth Low Energy communication traits. Bluetooth Low Energy (BLE) Hardware Abstraction Layer

This module defines the platform-agnostic trait for BLE functionality. Platform implementations (ESP32, nRF52, STM32WB) must implement this trait to provide BLE capabilities.

Usage

use feagi_hal::hal::BluetoothProvider;

// Platform layer provides the implementation
let mut ble: Esp32Bluetooth = /* platform init */;

// Start advertising
ble.start_advertising("FEAGI-robot").unwrap();

// Wait for connection
while !ble.is_connected() {
    // Poll or sleep
}

// Send/receive data
ble.send(b"Hello FEAGI").unwrap();
let mut buf = [0u8; 64];
if let Ok(len) = ble.receive(&mut buf) {
    // Process received data
}
