Re: [Bluez-users] connectionless L2CAP

[Aleksandar Kanchev <kanchev@in.tum.de>]

Hello Marcel,

I'm actually trying to send a data packet between 2 bluetooth devices 
over 100 meters. I haven't went really deep into the bluetooth specs, 
but I assume that because of the long range a connection might not be 
possible, so that's why I just want to broadcast some packets and hope 
that some will arrive at the other end. Is this possible ?

Btw./l2test with 00:00:00:00:00:00 fails too, but the bluetooth baseband 
specification section 3.3 says that "ACL packets not addressed to a 
specific slave are considered as broadcast packets and are read by every 
slave". I have 1 device in range (I can see it with hcitool scan, l2test 
succeeds with that device).

Thanks
