[Bluez-devel] More then 2 RFCOMM channels open

[Bluez-devel] More then 2 RFCOMM channels open

[elad wertzberger]

Hi All,

We are students building a network from bluetooth
modules and bluez.
We connected 2 units in Serial Port Profile using minicom application
and RFCOMM channels.
We want to pass information from Module A to Module B through Module C
(A -> C -> B).
Like a repeater in bluetooth.
the problem is that we cannot open RFCOMM connection between more then
2 units. (??)
1. Is it possible to open in bluez an RFCOMM
   connection with 3 units, means from A to C and
   from b to C at the same time ?
2.Do you support it in software ? is there a hardware
  limitation ? (with bluetooth 1.1)
3.Can we open more then one minicom at the same time?

Best Regards,
Elad wertzberger

bluez has no software limitations here.  This should be possible, but may be
limited by your hardware.  You'll want to figure out which chipset your
dongles are using and then make sure that they can support scatternets.  You
may also need to manually perform role switches to minimize scatternet
formation.  You can open more than one minicom at a time.
