[Bluez-devel] dumping/debuging ttySX ...

Hi,

I'm currently adapting bluez to run a bt chip via uart. it seems that
modifying hciattach initialization code might be enough. however i'm having
trouble after initialization whenever the driver take the socket over
(N_HCI). for some reason, the chip sends lots of "invalid packet events" and
"startup events".

before going further, i need to know what is sent over uart (i.e. every
single byte in each direction). hcidump seems to be a bit too high-level.
what would you recommend to spy transparently the ttyS0 ?

thanx for any help

what kind of Bluetooth chip is it that you use?
