我使用藍牙在 Fedora 26（帶有 KDE）盒子和我的 Android 裝置之間傳輸檔案。我有 4 台配對的裝置：2 部手機和 2 台桌子。 Android 版本為 5 和 7。主要原因是我不知道“文件傳輸”是如何啟用的。
在其他 3 台裝置上，我可以將檔案從 Fedora Box 發送給它們，反之亦然，但 obexftp 無法正常運作。當我嘗試透過 Dolphin 打開與他們的 obexftp 連線時，Dolphin 根本拒絕這樣做。
從 CLI (bluetoothctl)：

從 Android 方面來看，所有裝置都具有完全相同的藍牙設置，因此，我懷疑這 3 台裝置上的藍牙實現與 HTC 的不一樣，或者我需要在我的 Fedora 上做一些事情。任何幫助確定我需要更改/啟用的內容將不勝感激。
