    Hi, i am in a group that is developing a bluetooth firmware (in C
language). We are developing the hci host, baseband, lmp.
   I would like to test the hci host with bluez, to see if the packets that
i am expecting are right. How can i use bluez to do this?

  Tks!

Hi Dalmo,

is this an open project? What hardware are you using for the radio and
the baseband?

If you have USB or UART as transport then you don't need anything
special. If you only have the raw HCI packets, then you might wanna look
at the hci_vhci kernel module which allows you to write a virtual
Bluetooth adapter. The hciemu program for example is using it to emulate
a HCI device.

Regards

Marcel

Hi Marcel, i would like to know if is possible to create a program in C that
receive HCI packet from bluez. Is it possible?

as I said, you need to use the hci_vhci kernel module and then write a
program that feeds HCI data into /dev/vhci and back to your system. The
hciemu program is doing something like this.
