[Bluez-devel] zeevo module on uart

[Bluez-devel] zeevo module on uart

[Simon Vogl]

hi,
I am trying to talk to a Zeevo BT module (tc2001p chip on it) which is
attached to an xscale processor via serial.
When I start hciattach, I get an error message (and I cannot talk to the
device later on):

root@tinypxa263:~# hciattach ttyS1 any
h4_recv: Unknown HCI packet type f1

The current kernel is 2.4.19-rmk7-pxa2 +local patches, bluez* 2.18
Is this a kernel issue or is something else in my setup wrong?
thanks
Simon

the support for the 2.4 kernel series is limited as you now. So I can't
provide you any details. However if the Zeevo module capable of working
with H:4 and doesn't need any special initialization, then this can only
mean the the serial port or baud rate settings are wrong.

Regards

Marcel

Thanks Marcel,
just wanted to know if there are some obvious limitations - I will play 
around with
the hardware settings a little bit more ;)
have a nice evening,
simon

Re: [Bluez-devel] zeevo module on uart

[Simon Vogl]

the module works now, after some experimenting, the following two
lines do the trick:

         setserial /dev/ttyS1 baud_base 921600 divisor 1 spd_cust
         hciattach ttyS1 any 921600
interestingly, hciattach alone did not manage to start communicating, als=
o
not with the -s option (the zeevo firmware is configured to communicate a=
t
921600 bps).

Now all I need to do is port a decent 2.6 kernel...
