如何利用PHP与Bluetooth协议进行无线设备通信

<?php
shell_exec("sudo hciconfig hci0 up"); // 打开蓝牙设备
shell_exec("sudo hciconfig hci0 piscan"); // 开启可见性
shell_exec("sudo hcitool scan"); // 扫描附近的设备
?>

<?php
$command = "sudo bluez-test-device trusted {device_address} yes"; // 将device_address替换为实际设备的地址
shell_exec($command);
?>

<?php
$command = "sudo rfcomm connect {device_address} 1"; // 将device_address替换为实际设备的地址
shell_exec($command);
?>

<?php
$address = 'localhost';
$port = 12345;

$socket = socket_create(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
socket_bind($socket, $address, $port);
socket_listen($socket);

$client = socket_accept($socket);
$data = socket_read($client, 1024);
socket_close($client);

echo "接收到的数据：" . $data;
?>

<?php
$address = 'localhost';
$port = 12345;
$data = 'Hello, Bluetooth!';

$socket = socket_create(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
socket_connect($socket, $address, $port);
socket_write($socket, $data, strlen($data));
socket_close($socket);

echo "发送的数据：" . $data;
?>
