I think X50v bluetooth is Texas Instruments BRF6150

Hi everybody,

I think the X50v bluetooth chip is probably the TI BRF6150.

And a driver for it seems to exist for the hx4700: 
http://
www.handhelds.org/projects/hx4700.html On the hx4700,
the 
bluetooth is lists as hooked up to the 'BT UART', which on
the hx2000 
page (http://www.handhelds.org/moin/moin.cgi/HpIpaqHx2000Gpio) is listed 
on the same GPIO's as the wiki page for the x50v 
(http://handhelds.org/moin/moin.cgi/DellAximX50Hardware
)...

The hx2750 has the 6150 too 
(h
ttp://www.handhelds.org/moin/moin.cgi/HpIpaqHx2000)

perhaps the users 'beemer' and/or 'mikelspikel' on this
thread in the 
forum below can help:

This is also an interesting link about brf6150/hx4700 and
'bts' 
"bluetooth script": 
http://sourceforge.net/mailarchi
ve/forum.php?thread_id=7533300&forum_id=1881

Also see http://www.handhelds.org/moin/moin.cgi/HpIpaqHx4700Dri
vers : 
"Status: Bluetooth support is functional. To start
bluetooth, "hciattach 
-S /etc/bluetooth/TIInit_3.2.26.bts ttyS1 texas". To
stop, 'killall 
hciattach'"

This is why I think the BRF6150 is the one:

Fisher's webpage has a chip 'Smallest out one' as 'B615CG1',
but it's a 
small chip and might as well be 'B6150 G1', eh?

And this:
'mikelspikel' on

"The bts from the x50v dump was intended to initialize
a TI BRF6150"

And this:

"New Widcomm BT Stack Install/Uninstall Package for
Axim X50"

Has a link to a file
"BroadcomBluetoothStackX51V05.zip", which after 
unzip/cabextract shows this:

Somebody posts "the BT Radio chip (TI BRF6150)"

And this:

The HP ipaq hx4700, which has very similar specs, has the
BRF6150

http://
www.handhelds.org/projects/hx4700.html

And this (ok this one is a far fetched one):

"While the Texas-based engineers at Dell didn't put a
digital camera in 
the new X50 series"...

Maybe the Dell Texas engineering center is close to the TI
bluetooth center?

PS: The 'xda' has the BRF6150 too, and the bluetooth serial
is listed as 
status 'works' with linux and a comment '115200. 921600 with
the TI 
*.bts - not tested. Bt irq ???' and  'Bluetooth manager -
Works - Able 
to pair other devices.'
