很可惜，这个连接不稳定，很快出现

Failed to pair: org.bluez.Error.AuthenticationFailed

[CHG] Device C0:50:27:32:09:33 Connected: no

出现这个问题后，再次连接不成功，即使重启树莓派也无效，但此时只需要重启SensorTile.Box就可以再次连接。

原因暂不明，怀疑是我手上的SensorTile.Box蓝牙不稳定造成。

试试手机连接是否正常

如果出现树莓派不能连的话，手机也搜不到对应设备。但手机不会主动把蓝牙弄死，用电脑或者树莓派把蓝牙弄死以后，只要sensortile.box重启就能恢复。我最近几天从最初的hex一步步试出来的，估计我用树莓接sensortile.box只能考虑串口或者读文件了。

弄死是执行了什么操作 是不是sensortile.box处于等待连接状态 没有再次开启广播
要不你参考一下官方APP的源码看看 或者在被弄死后看一下板子上的按键试试有没有什么反应

嗯，正在尝试，谢谢。。。
