uniapp 蓝牙小程序-兼容安卓和iOS

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 = nullconst 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。getAddc(str) {let itotal = 0,len = str.length,num = 0;var tempTotal = "";while (num < len) {let s = str.substring(num, num + 2);itotal += parseInt(s, 16);num = num + 2;if (itotal >= 256) {itotal = parseInt((itotal - itotal % 256) / 256) + itotal % 256}}itotal = 255 - itotalreturn itotal.toString(16).padStart(2, '0')}
