I've been trying to follow the instructions to get a D-LINK DBT-120 Bluetooth adapter to work with Fedora Core 4 using a Treo 650 PalmOS phone on the Sprint network.

I've been battling it for a while and since I'll be traveling a lot very soon (the reason I'm trying to get this working) and I'm running out of time so I'm asking for help.

Basically, the instructions I'm following are these:

http://www.gurulabs.com/goodies/Using_Linux_and_Bluetooth_DUN_with_the_Treo650.php

Everything went fairly well except when I finally try to bring up the PPP connection I get an error:

[root@dell8100 bluetooth]# ifup treo
Failed to activate treo with error 7

/var/log/messages reports the following details:

Aug 24 23:13:16 dell8100 ifup-ppp: pppd started for treo on /dev/rfcomm0 at 115200
Aug 24 23:13:16 dell8100 pppd[30712]: pppd 2.4.2 started by root, uid 0
Aug 24 23:13:17 dell8100 hcid[30014]: link_key_request (sba=00:13:46:47:64:27, dba=00:07:E0:03:D3:99)
Aug 24 23:13:18 dell8100 pppd[30712]: Failed to open /dev/rfcomm0: Connection reset by peer
Aug 24 23:13:18 dell8100 pppd[30712]: Exit.

FYI:
00:13:46:47:64:27 is my D-Link Bluetooth adapter
00:07:E0:03:D3:99 is my Treo 650

I tried to follow some of the other diagnostics I found on the list to no avail:

# l2ping 00:07:E0:03:D3:99
Ping: 00:07:E0:03:D3:99 from 00:13:46:47:64:27 (data size 20) ...
Recv failed: Connection reset by peer

During that time /var/log/messages reported the following:

Aug 24 23:14:14 dell8100 hcid[30014]: link_key_request (sba=00:13:46:47:64:27, dba=00:07:E0:03:D3:99)

If I try to scan for the phone it DOES appear to be found:

# hcitool scan
Scanning ...
        00:07:E0:03:D3:99       MYTREO

One thing I noticed is that when I remove the /etc/bluetooth/link_key and then try to start PPP the phone asks me for my PIN again. I put it in and that time it seems to open the /dev/rfcomm0 port. It then tries to send AT commands which don't respond so it times out and fails.

Help!

Hi Greg,

what version of bluez-utils is installed with your FC4? Provide us with a "hcidump -X -V" for that failure.

Regards

Marcel

Since I got no response in several days I take it nobody knows why the D-Link bluetooth adapter doesn't work with Fedora Core 4.

Can someone recommend a USB Bluetooth dongle that IS known to work well with Fedora Core 4, specifically for DUN support through a Treo 650 phone?

Hi Gregory,

this can happen, because I am not always around. However the the D-Link is working fine. Do you set yourself into security mode 3? Show us the output of "hciconfig -a".

Regards

Marcel

Hi Gregory,

read the specs. and you set auth and encrypt in hcid.conf. Don't do this until you know what this implies.

Regards

Marcel

The howto I followed originally already had me enable authentication and encryption in the hcid.conf:

        # Authentication and Encryption (Security Mode 3)
        auth enable;
        encrypt enable;

of course you can use it, but the default is off and that is for a reason. Security Mode 3 is not what you want, because it implies link level security and not all devices can deal with that. You Treo is at fault here and not the D-Link dongle.

Oh!!! I guess the Howto I followed was wrong. It recommended using the authentication and encryption. As soon as I turned those off it worked like a charm!
