bluetoothctl没有默认控制器可用 [英] bluetoothctl No default controller available
问题描述
这里有点连线.
我有一个问题是bluetoothctl总是说没有默认控制器可用".我发现有很多人对我有同样的问题.但是情况与他们有些不同.
I have a problem is bluetoothctl always said "No default controller available". I found there are many people had same problem with me. But the situation is a bit different from them.
我可以看到我的hciconfig -a具有如下信息
I can see my hciconfig -a have information like below
hcitool开发人员似乎也没有问题.
And hcitool dev seems no problem as well.
但是我不知道为什么我的bluetoothctl总是说没有默认控制器可用"
But I have no idea why my bluetoothctl always said "No default controller available"
即使我调低和调高hci0数次.总是有同样的问题.
Even I turn down and turn up hci0 several times. It always in the same problem.
顺便说一句,我的BlueZ是5.39.我在buildroot上尝试了该实验.内核是3.10
BTW, my BlueZ is 5.39. And I tried this experiment on buildroot. Kernel is 3.10
推荐答案
出现相同的问题.使用:
$ sudo bluetoothctl
Had the same problem. Use:

然后自动找到控制器.我还尝试了 https://www.raspberrypi.org/forums/viewtopic.php? t = 207025 之前.也许这影响了解决方案.
Then the controller was found automatically. I also tried https://www.raspberrypi.org/forums/viewtopic.php?t=207025 before. Maybe this effected the solution.
