问题描述:

当我试图使用gatttool和bluetoothctl连接到蓝牙设备时,gatttool得到了“连接被拒绝”,但bluetoothctl成功连接到它。不同的连接结果在gatttool和bluetoothctl与覆盆子pi 3蓝牙

bluetoothctl和gatttool有什么区别?

如何使gatttool工作,因为我需要在gatttool中使用char-write-cmd命令?

我在Linux上有同样的问题UBUNTU 17.04 bluetoothctl没有问题,但gattool没有连接 – Zibri

解决方案:只需将-t随机添加到gatttool命令行,它就会连接!
