Bluez 在配对 Airpods 时卡住了身份验证

Bluez 在配对 Airpods 时卡住了身份验证

按住airpod按钮直到LED灯变白并闪烁后，我尝试与

[bluetooth]# pair <mac-address>

返回

Attempting to pair with 18:F1:D8:36:53:FB

然而，它只是停留在那里很长一段时间，直到airpod的LED再次变绿，我收到以下错误

Failed to pair: org.bluez.Error.AuthenticationCanceled

这让我相信它在某种程度上陷入了身份验证步骤。

我的airpod能够在我的其他ubuntu机器和我的android手机上配对，所以我相信这是这台电脑的蓝牙设置的问题。

输出btmon

答案1

这个答案解决了我的问题。特别是，我必须ControllerMode = bredr设置/etc/bluetooth/main.conf
