问题描述： 在android上 wx.getBLEDeviceService得到了错误的device service uuid，在IOS上是正确的。 说一下问题： 1. 通过扫描得到deviceID: F2:13:4A:B4:EA:75 2. 找到其advertiesServiceUUIDs:["6e400001-xxxxxx-e50e24dcca9e"] 3. 通过creatBleconnection后读取service uuid变成了"000018xxxxx" 4. 有一次调试偶然间看到这个uuid是一个叫UIKI-sport-002的设备的数据，但是我周围没有这个设备，其他蓝牙软件扫描不能发现这个设备，我怀疑是你们hardcode的。或者缓存的原因。(最后一张图UIKI-sport-002我怀疑这个设备是你们虚拟出来的) 具体看代码和截图： 相应的代码和log： var topClass = this;         var currentDeviceId=topClass.data.deviceId;         wx.createBLEConnection({             deviceId: currentDeviceId,             success: function (res) {                 console.log("success create a connection to device", currentDeviceId, res);                 topClass.data.connected = true;                 /**                  * 连接成功，后开始获取设备的服务列表                  */                 wx.getBLEDeviceServices({                     // 这里的 deviceId 需要在上面的 getBluetoothDevices中获取                     deviceId: currentDeviceId,                     success: function (serviceRes) {                         console.log("success to get device services", currentDeviceId, serviceRes);                         topClass.setData({ services: serviceRes.services });                         serviceRes.services.forEach(function (devService) {                             console.log('loop device service:', devService);                             //if (devService.uuid.indexOf("6e400001-b5a3-f393-e0a9-e50e24dcca9e") != -1) {                             topClass.setData({ serviceId: devService.uuid });                             console.log('getBLEDeviceCharacteristics:', currentDeviceId, devService.uuid);                             topClass.getBLEDeviceCharacteristics();                             //}                         });                         if (topClass.data.writeCharId && topClass.data.notefyCharId) {                                      wx.showModal({                                     title: '提示',                                     content: '建立连接成功，可以发送数据了'                                 });                         }else{                             wx.showModal({                                     title: '提示',                                     content: '找不到正確的characteristics'                                 });                                 return;                                 wx.closeBLEConnection({                                   success: function(res){                                     console.log("success closebleconnection");                                   },                                   fail: function(res) {                                      console.log("failed closebleconnection");                                   },                                   complete: function(res) {                                     // complete                                   }                                 })                             }                     },                     complete: function (res) {                     }                 })             },             fail: function (res) {                 console.log("failed to connect to device:", res);             },             complete: function (res) {             } [图片] [图片] [图片]
