Let's see how the adapter works:

Connecting to the peer

In this case, a Samsung SGH-C3212 is on the other end. The computer is allowed access.

Try to list files on the phone:

$ obexftp -b A0:07:98:91:D5:4E --noconn --uuid none --nopath --list

Suppressing FBS.

After each 'Connecting...', the phone asks for access and I press Yes.

$ sudo rfcomm connect 1 A0:07:98:91:D5:4E

Can't connect RFCOMM socket: Operation now in progress

Errors seen in dmesg:

[2155116.942196] hci_cmd_task: hci0 command tx timeout

[2155251.927147] hci_cmd_task: hci0 command tx timeout

There was an idea that downgrading bluez may help. Here is the result with bluez-4.19-1.5.x86_64:

$ obexftp -b A0:07:98:91:D5:4E --noconn --uuid none --nopath --list

Suppressing FBS.

However, the phone now sees the dialup capability of the computer beside the audio. With bluez-4.88 there was only audio available.

Some reports about the timeout error:

I ended up using a machine with Windows XP for this task.
