小程序连接和写入打印机的过程都ok，可是打印机就是没有相应！求解 代码贴出： // 初始化蓝牙适配器   initializeBluetooth: function () { var that = this; if (!wx.openBluetoothAdapter) { console.log('蓝牙适配器打开失败，请检查微信版本或手机是否支持小程序蓝牙模块！') } else { wx.openBluetoothAdapter({ success: function (res) { that.setData({ msg: "初始化蓝牙适配器成功！" }) wx.getBluetoothAdapterState({//获取本机蓝牙适配器状态 success: function (res) { console.log('本机蓝牙适配器状态：') console.log(res) } }) } }) } }, //搜索获取已发现设备   searchBluetooth: function () { var that = this;

手机远程调试突然之间成这样了   下午四点多突然就成这样了，一扫瞄就显示已结束  请重新开始  手机上显示白板  什么都没有 [图片]

通过测试      manager.start({ lang: "zh_CN" })会造成报错 wx.getRecorderManager is not a function;at pages/index/index streamRecord function;at api request success callback function TypeError: wx.getRecorderManager is not a function 怎么解决[图片]
