Thanks Marcel,

Here is the output from my command:

# hcitool cmd 0x02 0x0003 0x01 0x00 0x00 0x05 0x00 0x01 0x06 0x00 0x10
0x00

< HCI Command: ogf 0x02, ocf 0x0003, plen 10

  01 00 00 05 00 01 06 00 10 00

> HCI Event: 0x0f plen 4

  00 01 03 08

I looked in the "BLUETOOTH SPECIFICATION Version 1.1" for the HCI Event
of 0x0f.  I am not confident in reading the specification.  But I think
this event 0x0f = Command Status.  And the Event Parameters:  (0) "00" =
Command currently in pending. 

 

Not sure if this indicates a success (or just pending not sure yet of
success).  Additionally, I am using bluez-libs&bluez-utils2.10.  Should
I reference the "BLUETOOTH SPECIFICATION Version 2.0 + EDR" instead?  I
found version 2.0 at "Bluetooth.org" web site.  AND the version 2.0 spec
is slightly different.  For example the error codes listed in 2.0 are
different.  

 

Sometimes with the hci cmd for sniff mode I get:

# hcitool cmd 0x02 0x0003 0x01 0x01 0x00 0x00 0x05 0x00

0x01 0x06 0x00 0x10 0x00

< HCI Command: ogf 0x02, ocf 0x0003, plen 11

  01 01 00 00 05 00 01 06 00 10 00

> HCI Event: 0x0f plen 4

  02 01 03 08

 

Here the HCI Event indicates "Status" of 0x02.  

Version 1.1 = 0x02 No Connection.

Version 2.0 = 0x02 Unknown Connection Identifier

 

Maybe it is only semantics... either way I do not understand what either
really mean.  For the sniff mode I have setup a bnep connection.  I can
ping "host", I have static IPs setup.  And 

hcitool con

Connections:

        < ACL 00:02:72:41:2E:1D handle 1 state 1 lm MASTER

 

Should this indicate "SLAVE"?  Somes times hcitool con will show SLAVE
instead.  Your advice on what spec to use and how to decipher hictool
output is appreciated.
