[Bluez-users] Hcidump stays in waiting state after RFCOMM "PN CMD" packet

[Steve MOREAU]

Hello,

I do a message again but I don't know what to do... I spent three days to
read bluez archives and Marcel pieces of advice but I still don't know if
my bluetooth trace is normal... After several connections, hcidump waits
there :

> ACL data: handle 41 flags 0x02 dlen 18
    L2CAP(d): cid 0x0041 len 14 [psm 3]
      RFCOMM(s): PN CMD: cr 1 dlci 0 pf 0 ilen 10 fcs 0x70 mcc_len 8
      dlci 2 frame_type 0 credit_flow 15 pri 0 ack_timer 0
      frame_size 319 max_retrans 0 credits 0
< ACL data: handle 41 flags 0x02 dlen 8
    L2CAP(d): cid 0x0041 len 4 [psm 3]
      RFCOMM(s): DM: cr 1 dlci 2 pf 1 ilen 0 fcs 0x73

I can't find anything relating to PN CMD on the Internet... Could you hel=
p
me please ? Could you recommend me a document to read in order to
understand ? I'm completely without more ideas to solve this problem :'(

Thanks in advance

Steve MOREAU

what you see is an request for using RFCOMM channel 1 and the other
sides rejects it. Check if you really have a service running on that
channel.

Marcel

Hi Michal,

actually this is not possible, because I am at a wedding that weekend
and before that I am in Warsaw at IT-Underground.

Done.

Marcel

Re: [Bluez-users] Hcidump stays in waiting state after RFCOMM "PN CMD" packet

[Steve MOREAU]

Thanks Marcel

I'm begginner with Bluetooth and... in fact I don't know what to do that.
I'm using Linux and I tryed several things without success.
As my PC is a slave and can't connect to the bluetooth device (this last
one initiate connection when it wants to send data), I couldn't use rfcom=
m
program... Should I launch rfcomm with special options or a ppp service o=
r
someone like that ?
Sorry for these newbie question, and thanks again

Regards,

Steve

how should I know if you don't tell what you really wanna do. I only
commented on your snippet of hcidump ;)
