obexftp -l fails, return code 81

0

I am currently attempting to use obex tools to browse (and later mount) the file system of an Android device (7.1.1). When I try to list using obexftp -l, it simply returns nothing. I have tried almost every possible combination of file parameters after -l, but still get the same error. My end goal is to use obexfs to mount, but feel this is an intermediate stepping stone. Details below.

After continuing to try many different things, I realized that is was more than likely the Android device having the issue. The solution is that the Android device needs to have an FTP Service running in order to utilize obexftp -l or obexfs. I achieved this by installing ES File Explorer on the Android device and selecting 'bluetooth' under the 'Network' tab. This opens an Obex FTP path on Bluetooth channel 20. The code below now functions; as well as obexfs.

obexftp -b D4:63:C6:XX:XX:XX -B 20 -U none -l
