pand and sniff have nothing to do with each other -- they are handled at
different levels and are so (in my understanding) relatively
independent.=20
Can you do a role switch with the device? That might have some effect.
Numbers are LSB/MSB, so I think you have the order of your connection
handle bytes reversed.
The exact sequence that works for me is:
hcitool cmd 0x02 0x0003 0x06 0x00 0x80 0x00 0x40 0x00 0x02 0x00 0x08

Thank you Trevor,
You rigth, but still doesn`t work. I`ve ben tried many changes of

but my dongle do not enter in sniff mode. There is any objection against
sniff mode and
a pand connection work together ?

Then you've not been looking very hard.
Since you're sending raw commands, bypassing BlueZ and talking directly
to the controller, perhaps you should read the HCI specification.
Bluetooth 2.0 + EDR spec, volume 3, part E, section 5.2, page 375:
* Unless noted otherwise, all parameter values are sent and received
in Little Endian format

EUREKA, EUREKA, it is working, it is working !!!!! You are right it is just a reversed
sequence of MSB/LSB, but I didn`t find it write in any where.
Thank you for your help !
