ofono enable-modem 失败，出现 dbus.exceptions.DBusException：org.ofono.Error.Failed：操作失败

我正在尝试让 Ubuntu 20.04 将 AirPods Pro 识别为耳机（而不仅仅是耳机）。我尝试按照这个答案。

list-modems返回以下输出：

[ /phonesim ]
    Online = 0
    Powered = 0
    Lockdown = 0
    Emergency = 0
    Interfaces = 
    Features = 
    Type = hardware

但是，当我尝试enable-modem从刚刚签出的ofonogit repo（提交 285fad8f39d46a5f0a0f9d194789978227558d1e）运行命令时，出现以下错误：

Connecting modem /phonesim...
Traceback (most recent call last):
  File "./enable-modem", line 20, in <module>
    modem.SetProperty("Powered", dbus.Boolean(1), timeout = 120)
  File "/usr/lib/python3/dist-packages/dbus/proxies.py", line 72, in __call__

    reply_message = self.send_message_with_reply_and_block(
dbus.exceptions.DBusException: org.ofono.Error.Failed: Operation failed

这个错误是什么意思？我该如何解决它？

答案1

问题是我没有停止phonesim跑步，这就是enable-modem我抱怨的原因。

因此命令

ofono-phonesim -p 12345 /usr/share/phonesim/default.xml

需要在运行之前保持运行enable-modem。请参阅我的回答，了解如何自动执行此操作：https://askubuntu.com/a/1278587/119592
