Are you sure your connection handle is right? I've seen connection
handles of 0x42 or 0x00 but nothing like 0x1006. You can find out the
connection handle with "hctiool con" after you've made the pan
connection.
I've found that getting sniff mode set up can be very fickle. depends
on firmware and other random parameters, so... can take some fiddling.=20
As far as I know BlueZ provides no direct support for sniff, and so I've
always used "hcitool cmd" to generate the sequence...

The Command Status event shows error code 0x12 =3D Invalid HCI Command
Parameters.
This means that the controller didn't like one of the parameters to the
sniff mode command.
The sniff mode command you gave had the parameters:
Connection handle: 0x1006
Sniff Max Interval: 0x0000
Sniff Min Interval: 0xff10
Sniff Attempts: 0x00f7
Sniff Timeout: 0x??07
Notes:
The connection handle is invalid. The valid range is 0x0000..0x0eff
The maximum interval is invalid. The valid range is 0x0002..0xfffe
The minimum interval is invalid. The valid range is 0x0002..max
interval.
The sniff attempts is highly unusual (but not actually invalid).
The sniff timeout field is truncated, it should be two bytes.
So, it's not surprising that the controller is rejecting it.
Where is the sniff mode command being generated? How is it getting
through the BlueZ APIs to generate such an invalid event? Are the
normal APIs being bypassed and is a raw command being sent.
