Subject: Re: [Bluez-users] RFCOMM Connect problem, need help to understand HCIDUMP output
Date: Thu, 14 Apr 2005 06:08:19 +0200 [thread overview]
Message-ID: <200504140608.19450.magnus.larsson@callista.se> (raw)
In-Reply-To: <200504100032.15053.magnus.larsson@callista.se>
Can someone help me to describe what the HCIDUMP in the end of this message
says is wrong?
Does anyone have a URL to some doc that explain the HCIDUMP output?
I think the following part is of interest (see below for the full hcidump -
output):
> ACL data: handle 0x002e flags 0x02 dlen 8
L2CAP(d): cid 0x0040 len 4 [psm 3]
RFCOMM(s): DM: cr 1 dlci 2 pf 1 ilen 0 fcs 0x73
< ACL data: handle 0x002e flags 0x02 dlen 8
L2CAP(d): cid 0x0048 len 4 [psm 3]
RFCOMM(s): DISC: cr 1 dlci 0 pf 1 ilen 0 fcs 0xfd
Regards,
Magnus.
