服务器地址对应目录下的文件明明变了，但是本地永远用最早的那个资源，不更新，不更新，不更新。。。。。 const backgroundAudioManager = wx.getBackgroundAudioManager() backgroundAudioManager.src = '固定网路路径'

蓝牙设备收到任何数据，返回对应的数据。 现在用安卓手机， 发送AA5504B10022B5 收到AA5504B10022B5 但是用苹果手机， 发送AA5504B10022B5 收到4552522b41540a 发送接口： sendfun: function () { var that = this; var hex = 'AA5504B10022B5' var typedArray = new Uint8Array(hex.match(/[\da-f]{2}/gi).map(function (h) { return parseInt(h, 16) })) console.log(typedArray) console.log([0xAA, 0x55, 0x04, 0xB1, 0x00, 0x00, 0xB5]) var buffer1 = typedArray.buffer console.log(buffer1) wx.writeBLECharacteristicValue({ deviceId: that.data.deviceId, serviceId: that.data.serviceId, characteristicId: that.data.characteristicswrite, value: buffer1, success: function (res) { // success console.log("success  指令发送成功"); console.log(res); }, fail: function (res) { // fail console.log(res); }, complete: function (res) { // complete } }) }, 接收接口： wx.onBLECharacteristicValueChange(function (characteristic) { console.log(`characteristic ${characteristic.characteristicId} has changed, now is ${characteristic.value}`) console.log('characteristic value comed:', characteristic.value) console.log(that.buf2hex(characteristic.value)); }） 转换接口： buf2hex: function (buffer) { // buffer is an ArrayBuffer return Array.prototype.map.call(new Uint8Array(buffer), x => ('00' + x.toString(16)).slice(-2)).join(''); }, 请帮忙看看！！！
