Hi Kasper,
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.
you can't since that is the job of the link manager and not the host
stack.
- 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
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.
Regards
Marcel
