Hi
I am trying to compare some different Bluetooth setup. Doing that I
would like to try with different baseband packet types.
So far I have been trying in two scenarios using hciconfig hci0 ptype
<type> and that seems to work, at least in the case where I am using
RFCOMM sockets for communication. But judging from the transfer rate it
does not seem to work using a PAND/BNEP setup. This leads to the
following questions:
- How can I observe the currently uses packet type? I have been trying
with hcidump and even parsed it with wireshark but can't really find the
identifier that identifies witch packet type currently is in use.
- Can I by somehow set the packettype using setsocktop() on a rfcomm
socket ? I have been look to find documentation on the content of the
sockopt struc used but can't really find any. I have also tried looking
in the code but can't figure out how to manipulate the packet type else
that using hciconfig
Thanks

you can't since that is the job of the link manager and not the host
stack.

Don't mess around with packet types. Really, I mean it, don't. Leave
the default and leave the rest up to the link manager.
