i noticed something interesting:

it seems like the setting the options in config file doesn't seem to be working.
if the options are set on command line (for e.g., hciconfig hci0 lm accept,master), it seems to work.

am i missing something?

hello,
i am trying to connect multiple bluetooth rfcomm clients to a single rfcomm server. only the first client is able to connect, the subsequent ones just fail.

here is my setup:
server
====
kernel: debian 2.6.12-1-686
bluez version 2.25
hardware: D-Link DBT-120 bluetooth dongle

client
====
National lmx9820 bluetooth module

on the server, i edited hcid.conf to change link mode to
lm accept,master;

despite that the linkmode always comes up as "slave, accept" when i do hciconfig -a.

i have included more info below. pls. see if you could give me some debugging tips.

thanks in advance,
deva
