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
(http://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/mailarchive/forum.php?thread_id=7533300&forum_id=1881
Also see http://www.handhelds.org/moin/moin.cgi/HpIpaqHx4700Drivers :
"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?

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

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.'
