Subject: [Bluez-users] use more than 16 HCI Devices at a time with BlueZ?

Hi List,

is there a possibility to use more than 16 HCI-Devices at a time with BlueZ?
And if not, where is this limitation set? (i would try to raise it on my
own then :) )

greetings,
Uli

Thanks a lot for this hint! :)

the kernel has no limit besides memory and the usual integer limit. In
userspace the limit is set to 16. A modified Bluetooth library would be
enough. I think the constant you look for is HCI_MAX_DEV or something.
Check the source code. It is easy to spot.

Marcel
