Re: Question on simple RFCOMM server

[Mateus Interciso <mateus@ouvi.com.br>]

Thank you, however the Peter solution (setting via ioctl) worked 
perfectly, and it fit's with what I need, since all the clients are 
already implemented via RFCOMM, I'll leave it like this for now, the 
only issue is having to run it as root for setting the link mode, but I 
can bypass this by using hciconfig before running the main server.
Or is there any configuration that can make a normal user change the 
default link mode?

Thanks all once again.
