Re: [Gumstix-users] Couple recent changes

[Triona R. <tri...@nu...>]

Hi,

I tried version386, and unfortunately got the exact same timeouts. Once a m
ajor BT process is attempted out (in my case file transfer), it freezes after a 
second, and then connection drops. Following this you cannot even scan or hcicon
fig -a without a timeout occuring. 

I didn't try the faster HWUART.

Ok, couple of recent changes in SVN for people to play 
with:

1. Nice patch contributed by Jean Tourrilhes which fixes module 
autoload
ing, so that we'll soon be able to probably remove the 
/etc/modules stuff.  Nee
d still to add pxa-ac97, mmc stuff, bluetooth 
stuff to /etc/modprobe.conf -- pl
us probably a handful of other 
modules.  I'll go through and do those real soon
 now.

2. Bluetooth fixes.  I can now reliably get BTUART doing HCI at 
230400bp
s.  For higher speeds, looks like we need the hardware flow 
control from the HW
UART, which we can do:

# /etc/init.d/S30bluetooth stop
# for i in 2 3 4 5;do ec
ho AF3 > /proc/gpio/GPIO4$i;done
[now edit /etc/default/bluetooth to change /dev
/ttyS1 to /dev/ttyS3 and 
change speed to 921600]
# /etc/init.d/S30bluetooth sta
rt

Please test this if you've been having bluetooth problems -- the HWUART 
sho
uld definitely work for everyone -- the BTUART is likely 
speed-sensitive and wi
ll work less well on 200MHz gumstix than on 
400Mhz ones, and will work better a
t slower serial speeds than at 
higher speeds.  If throughput isn't critical tho
ugh, you can do a lot 
of bluetooth stuff at 57600.  If throughput is critical, 
then right now 
you basically lose one serial port in exchange for working bluet
ooth.  
Once we get the new waysmall boards done with STUART as the 2nd serial 
port instead of HWUART, this will be somewhat less of an issue.
