Hello, I'm trying to get sniff mode working between two devices. My
understanding is that this is not directly supported by bluez
(http://mhonarc.axis.se/bluetooth-dev/msg03437.html), so I'm trying to
send the relevant HCI commands directly -- but I can't seem to get it to
work. A quick trace of all the information is below... basically, it
seems to send the command ok, but it just comes back with an error
(which I think I have translated to just "HCI parameter error"). Any
thoughts on what might be going wrong? =20
Cheers,
Trevor

run "hcidump -X -V" in the back for the decoding.
