ZMK 不错！60 不与 Ubuntu 配对？
ZMK nice!60 does not pair with Ubuntu?
我刚刚构建了我的第一个自定义键盘，但在配对时遇到了问题。
我有一个 nice!60 pcb，我正试图让它与 Ubuntu 20.04 配对。当我第一次打开它时，它运行良好，但一天后，它根本无法连接。
我试过以下方法：
- 正在清除主机配置文件并重新连接
- 重置 pcb
- 正在重置 Ubuntu 的蓝牙服务
- 连接到不同的 Ubuntu 20.04 设备
我每次都遇到同样的问题。我尝试配对设备，但 Ubuntu 自动拒绝配对或滚轮旋转然后设置对话框冻结。
有什么想法吗？如果有任何帮助，我将不胜感激。
我正在根据熊猫先生的建议更新此 post。这是 sudo btmon 的输出：

在熊猫先生（上图）的帮助下以及在 gatttool 中的一些挖掘，我成功地连接上了它。
由于 Nice!60 PCB 是一个 BLE 设备，使用它似乎很挑剔 Ubuntu，但我找到了解决方案。
sudo gatttool -t random -b E7:2D:83:06:AA:AB -I
[E7:2D:83:06:AA:AB][LE]> connect
从那里可以配对设备，并且配对成功。
注意：
-t 是将设备连接设置为 public 或随机的选项。似乎某些设备需要使用随机 LE 地址进行连接。 -b 是将静态地址提供给使用 sudo hcitool lescan 找到的 BLE 设备或在上面找到的更详尽的输出中的选项。 -I 使其成为交互式会话。
我刚刚构建了我的第一个自定义键盘，但在配对时遇到了问题。
我有一个 nice!60 pcb，我正试图让它与 Ubuntu 20.04 配对。当我第一次打开它时，它运行良好，但一天后，它根本无法连接。
我试过以下方法：
- 正在清除主机配置文件并重新连接
- 重置 pcb
- 正在重置 Ubuntu 的蓝牙服务
- 连接到不同的 Ubuntu 20.04 设备
我每次都遇到同样的问题。我尝试配对设备，但 Ubuntu 自动拒绝配对或滚轮旋转然后设置对话框冻结。
有什么想法吗？如果有任何帮助，我将不胜感激。
我正在根据熊猫先生的建议更新此 post。这是 sudo btmon 的输出：

在熊猫先生（上图）的帮助下以及在 gatttool 中的一些挖掘，我成功地连接上了它。
由于 Nice!60 PCB 是一个 BLE 设备，使用它似乎很挑剔 Ubuntu，但我找到了解决方案。
sudo gatttool -t random -b E7:2D:83:06:AA:AB -I
[E7:2D:83:06:AA:AB][LE]> connect
从那里可以配对设备，并且配对成功。
注意：
-t 是将设备连接设置为 public 或随机的选项。似乎某些设备需要使用随机 LE 地址进行连接。 -b 是将静态地址提供给使用 sudo hcitool lescan 找到的 BLE 设备或在上面找到的更详尽的输出中的选项。 -I 使其成为交互式会话。
