Hi all,

I have a bluetooth device here that has an LCD display. I want to be able t=
o=20
send arbitrary data to the device. This way I can (hopefully) make text=20
appear on the LCD display. The problem is, that I can not find enough=20
documentation to send the arbitrary data. So I'm hoping to find some help=20
here...

What I have done so far:
=2D Open the hci device
=2D Create a connection to the LCD device (I have no idea what all the ptyp=
e=20
flags (HCI_DM1 etc...) in hci_create_connection do :( ). This gives me a=20
handle to the LCD device.
=2D I now can send hci_send_req's by filling in ogf and ocf with e.g.=20
OGF_STATUS_PARAM and OCF_READ_RSSI to read the RSSI.

But, now I'm stuck. What function can I call to send arbitrary hex data?
Do I use hci_send_req and fill in other values for ogf/ocf and plug the dat=
a=20
into rparam? Or do I use another function? (which??)
Any help is appreciated!

Greetings
Rutger Hendriks
