withTimeout方法可以在搜寻设备时等待指定的秒数，如果30秒内未搜索到则取消搜索
/**
* 超时控制函数
* @param {Promise} promise 回调函数
* @param {number} timeout 超时时间, 默认10s
*/
export function withTimeout(promise, timeout = 10000) {
let timeoutEvent = null
const logicPromise = new Promise((resolve, reject) => {
promise.then((data) => {
if (timeoutEvent) {
// 清理超时
clearTimeout(timeoutEvent)
timeoutEvent = null
}
resolve(data)
})
})
// 创建一个新的 Promise 对象，用于处理超时情况
const timeoutPromise = new Promise((resolve, reject) => {
timeoutEvent = setTimeout(() => {
reject(`执行超时`);
}, timeout);
});
// 将两个 Promise 对象（原始的 promise 和超时的 promise）合并为一个新的 Promise 对象
return Promise.race([logicPromise, timeoutPromise]);
}计算数据校验和：
校验字节等于命令字节与所有数据字节之和的反码。求和按带进位加 （ADDC）方式计算，每个进位都被加到本次结果的最低位（LSB）。
举例：如命令字节=0x01；
数据=0xF0，0xF1，0xF2，0xF3，0xF4，0xF5，0xF6，0xF7，0xF8，0xF9，0xFA，0xFB，0xFC，0xFD，0xFE，0xFF，0x00，0x01；则校验字节0x01+0xF0+0xF1+0xF2+0xF3+0xF4+0xF5+0xF6+0xF7+0xF8+0xF9+0xFA
+0xFB+0xFC+0xFD+0xFE+0xFF+0x00+0x01 = 0x0F79;
0x0F+0x79 = 0x88；
校验字节 = 0xFF – 0x88 = 0x77。
