Authentication failure with Blueman applet and cell phone.

My phone is paired with my Slackware 14.1/64 bit system. On the Blueman devices applet, if I click the blue folder, I see a message pop up after a few seconds, "Failed to mount GT-I5510M to /home/cliff/obexfs/84:25

B:AD:C5:0E."

This is an older Samsung android phone. The android version is 2.2.2 and the model is GT-I5510M.

I ran hcidump to try and find out why the failure to mount. Here is the part of the trace I think show the most useful information.

Code:

> HCI Event: Command Status (0x0f) plen 4
    Authentication Requested (0x01|0x0011) status 0x00 ncmd 1
> HCI Event: Command Complete (0x0e) plen 10
    Link Key Request Reply (0x01|0x000b) ncmd 1
    status 0x00 bdaddr 84:25:DB:AD:C5:0E
> HCI Event: Auth Complete (0x06) plen 3
    status 0x05 handle 44
    Error: Authentication Failure

This leaves me with some questions.

How is authentication done for obexftp? I have not found any information on this. Any idea where I can find out what status 05 handle 44 means? ( probably just 'Authentication Failure' however, doc to confirm would be nice.

I know there is a file ~/.config/blueman/blueman.cfg. I don't know how its generated, or modified.

My main desktop system has three drives. I have the 14.1/64 bit system on sdb, and 14.1/32 bit system on sda. I have the phone paired with both versions of Slack. I can click the blue folder on the 32 bit system, it mounts the ~/obexfs/84:25

B:AD:C5:0E without problems. All the same hardware is used, so I'm as sure as I can be this is not hardware related.

I also tried copying the ~/.config/blueman/blueman.cfg file from the 32 bit system to the 64 bit system. The phone still pairs, however, the authentication error persists.

I have read a lot of online searches, have not found a solution.

BTW, this is not a high priority problem. I have Dropbox on the phone, and it copies photos to my system without problems. I also have Airdriod working.

My interest here is more of a learning experience.

Thoughts on how to proceed?

One other question. The blueman applet calls a script, /usr/libexec/blueman-open. Lines 6 and 7;

Code:

6 # Set to 0 if you want more debugging messages
        7 DEBUG=0

I set DEBUG to 0. Where do I find the 'more debugging messages'? There doesn't seem to be a log file that I can find.

An update.

I checked the versions of obex packages and bluez packages on both systems. They are the same, other than 32 bit and 64 bit packages on respective installs. Everything is up to date.

I decided to delete the pairing on my 64 bit system, and then re-create it. To my surprise I can now transfer files in both directions on the 64 bit system. The down side, is now the 32 bit system fails. I can no longer mount the phone via blueman applet. I did nothing to the 32 bit system.

For now, I will probably leave it this way, since the 64 bit system is my main system, and the 32 bit system is backup.
