I have a PXA 270 CPU based board running Linux 2.6.15. I have enabled =
the
IRDA device driver and have got it working. I use the =93 irattach =94 =
utility
to attach the device irda0. I use the OPENOBEX libraries on top of the =
IRDA
stack/driver to do some file transfer between a PALM and my board. I use =
the
sample irobex_palm3 application and obexftp to get this done. This is =
how my
application flows.=20

=20

STEP 1. Wait for a file from PALM.

STEP 2. On reception of the file, obexFTP another file to the PALM

STEP 3. Go to STEP 1

=20

I run this in a while(1).=20

=20

Everything is smooth except for one issue. Most of the times, after the =
TX
of the file via obexFTP it takes nearly 25 seconds before it could =
actually
start receiving my file from PALM again. I get these messages in that =
time,
=93IrLAP, no activity on link!=94

When I tried to debug, this was the major issue,=20

=20

Nomally the state transitions of LAP are                    XMIT_P ---
PCLOSE --- NDM

But in the case when it waits for 25 secs it is             XMIT_P --- =
NRM_P
(Tries with 24 retrans .. causing my delay) --- NDM

=20

Can someone help me how I could reduce this delay.=20
