I've been playing with Bluetooth this morning,
linking my Sony C1VFK Picturebook (with in-built Bluetooth)
to my Nokia 6310.
A couple of things puzzle me.
(1) Each time I connect the channel number increases by 1.
Eg on my fourth attemtp I used channel 4:
=======================================
Serial connection established.
using channel 4
Using interface ppp0
Connect: ppp0 <--> /dev/rfcomm0
rcvd [LCP ConfReq id=0x0 <auth pap> <mru 1500> <asyncmap 0xa0000>]
...
rcvd [IPCP ConfAck id=0x3 <addr 62.40.49.216>]
local IP address 62.40.49.216
remote IP address 10.6.6.6
=======================================
(2) For some reason I only succeed in connecting every other try.
On the odd attempts I get
=======================================
Script /etc/ppp/ip-up started (pid 6584)
Script /etc/ppp/ip-up finished (pid 6584), status = 0x0
Terminating on signal 2.
=======================================
(3) This is not really a Bluetooth query, I guess,
but I'm slightly puzzled by the fact that I cannot ping
the remote address, which is always 10.6.6.6
=======================================
[tim@martha 2004]$ ifconfig ppp0
ppp0 Link encap:Point-to-Point Protocol
inet addr:62.40.49.19 P-t-P:10.6.6.6 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:86 errors:0 dropped:0 overruns:0 frame:0
TX packets:108 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:35498 (34.6 Kb) TX bytes:11851 (11.5 Kb)
=======================================
(4) Also, I'm surprised I don't have to specify any nameservers
(in my /etc/resolv.conf).
Is that normal?
(5) Incidentally, the last obstacle that stopped me connecting
was that I needed "\r" in the ATD line of my chat-sequence
========================================
OK ATE0
OK ATV1
OK 'AT+CGDCONT=1,"IP","open.internet","",0,0'
OK 'ATD*99#\r\n'
TIMEOUT 60
CONNECT ""
========================================
Any suggestions or advice gratefully received.

this is pppd specific, so you must ask the PPP guys about that.

This is funny. I haven't seen this before. Maybe it is also a pppd
problem.

Can you ping any other address. Maybe your provider don't support the
ICMP protocol.

The PPP scripts will replace resolv.conf for your session.

Looks like a phone specific bug. Check with "hcidump -a" what the chat
script really sends.
