5个快速上手的Python PyBlueZ蓝牙开发技巧分享

import bluetooth

# 快速扫描附近蓝牙设备
print("正在扫描附近的蓝牙设备...")
devices = bluetooth.discover_devices(lookup_names=True, duration=5)

for address, name in devices:
    print(f"发现设备：{name} - {address}")

import bluetooth

# 创建RFCOMM服务器
server_socket = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
server_socket.bind(("", bluetooth.PORT_ANY))
server_socket.listen(1)

# 获取分配的端口号
port = server_socket.getsockname()[1]
print(f"服务器正在监听端口：{port}")

# 等待客户端连接
client_socket, address = server_socket.accept()
print(f"接收到来自 {address} 的连接")

from bluetooth.ble import DiscoveryService

# 扫描BLE设备
service = DiscoveryService()
ble_devices = service.discover(3)

if ble_devices:
    print("发现以下BLE设备：")
    for addr, name in ble_devices.items():
        print(f"  {name}: {addr}")
else:
    print("未发现BLE设备")

import bluetooth

# 在SDP中注册服务
server_sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
server_sock.bind(("", bluetooth.PORT_ANY))

# 注册服务信息
bluetooth.advertise_service(server_sock, "DataService",
    service_id="12345678-1234-5678-1234-567812345678",
    service_classes=[bluetooth.SERIAL_PORT_CLASS],
    profiles=[bluetooth.SERIAL_PORT_PROFILE]
)

import bluetooth

try:
    # 尝试扫描设备
    devices = bluetooth.discover_devices(lookup_names=True, duration=8)
    print(f"成功发现 {len(devices)} 个设备")

    print(f"蓝牙操作失败：{e}")
except Exception as e:
    print(f"发生未知错误：{e}")
