Title: Problems using IR port to connect to a SE Z600
Post by: ccrandal on June 03, 2004, 05:50:26 pm

While waiting for another bluetooth card to arrive, I wanted to use my Sony Ericsson Z600\'s IR port to establish a connection to the Z.  However, it doesn\'t appear to be doing anything.  I also tried with a SE T610 with lack of results.

I set up the connection to dial the number *99***2# and I\'ve tried the standard AT string, ATZ, and no string.  Looking at the /tmp/qpe-pppd-log file, I see it trying to dial the number:

send (ATDT*99***2#^M)

but it just hangs in the initialization stage.

I saw an old thread on this saying there\'s a bug in the newer Sharp ROMs (I think 3.10 and up) and the only way to fix is to revert to an older ROM.  Is this also the case with the Cacko Qt ROM 1.21a?

Thanks
Curt

I had no problems with IR GPRS and my Siemens S46 and AT&T with *99***1#.  I just used the GUI Network app to set it all up.  I currently use BT/T610/tmobile with *99***2# with the same GUI Network app.  No problem.

c860 w/ Cacko 1.21a.  I didn\'t test IR GPFS with 1.21a.  I think I was using 1.20 or 1.18.  I do not recall.  I do recall having to enter different \"Init commands:\" in the Network app. to get the best performance.  Hint: space delimit multiple commands, e.g. ATZ ATfoo = ATZ, wait for OK, ATfoo, wait for OK, etc...  To find the settings I googled for GPRS IR LINUX.

Try this:

echo 1 ] /proc/sys/net/irda/max_tx_window
echo 1000 ] /proc/sys/net/irda/min_tx_turn_time

Awesome!  The echos did the trick.  Thanks maslovsky.  Also, thanks datajerk for the info as well.  I did a google search and found some good stuff.
