问题解决了吗/

按楼主的方法已经开启了手机蓝牙，GPS和定位权限但还是搜索不到设备； {errMsg: "getBluetoothDevices:ok", devices: Array(0)} 红米手机测试， button4: function () { var that = this; //z字符转换 function ab2hex(buffer) { var hexArr = Array.prototype.map.call( new Uint8Array(buffer), function (bit) { return ('00' + bit.toString(16)).slice(-2) } ) return hexArr.join(''); } wx.getBluetoothDevices({ success: function (res) { console.log(res) if (res.devices[0]) { console.log(ab2hex(res.devices[0].advertisData)) } if (res.devices.length == 0) { that.setData({ msg: "未发现设备" }) } } }) }
