obexftp -l 失败，return 代码 81
obexftp -l fails, return code 81
我目前正在尝试使用 obex 工具浏览（并稍后安装）Android 设备 (7.1.1) 的文件系统。当我尝试使用 obexftp -l 列出时，它只是 returns 什么都没有。我已经尝试了-l 之后几乎所有可能的文件参数组合，但仍然出现相同的错误。我的最终目标是使用obexfs挂载，但感觉这是一个中间垫脚石。详情如下。

在继续尝试许多不同的事情之后，我意识到很可能 Android 设备有问题。解决方案是 Android 设备需要有一个 FTP 服务 运行 才能使用 obexftp -l 或 obexfs。我通过在 Android 设备上安装 ES File Explorer 并在 'Network' 选项卡下选择 'bluetooth' 来实现这一点。这将在蓝牙通道 20 上打开一个 Obex FTP 路径。下面的代码现在起作用了；以及 obexfs。
obexftp -b D4:63:C6:XX:XX:XX -B 20 -U none -l
我目前正在尝试使用 obex 工具浏览（并稍后安装）Android 设备 (7.1.1) 的文件系统。当我尝试使用 obexftp -l 列出时，它只是 returns 什么都没有。我已经尝试了-l 之后几乎所有可能的文件参数组合，但仍然出现相同的错误。我的最终目标是使用obexfs挂载，但感觉这是一个中间垫脚石。详情如下。

在继续尝试许多不同的事情之后，我意识到很可能 Android 设备有问题。解决方案是 Android 设备需要有一个 FTP 服务 运行 才能使用 obexftp -l 或 obexfs。我通过在 Android 设备上安装 ES File Explorer 并在 'Network' 选项卡下选择 'bluetooth' 来实现这一点。这将在蓝牙通道 20 上打开一个 Obex FTP 路径。下面的代码现在起作用了；以及 obexfs。
obexftp -b D4:63:C6:XX:XX:XX -B 20 -U none -l
