Hi.
I bought a CF Bluetooth card from a UK supplier's (ebuyer) budget range.
It said it was based on the CSR chipset, which seems to be reasonably
well supported. Should have done more research first really. :)
Anyway. It idents as:
Socket 0:
product info: "Compact Flash", "Bluetooth Card", "", ""
manfid: 0x0279, 0x950b
function: 2 (serial)
There's no manufacturer listed on it. The front says "CF CompactFlash
BluetoothTM". The back says "BluetoothTM CompactFlash Card" and "P/N:
CFBT02-N2".
Plugging the card into my Zaurus with the BlueZ packages installed led
to no luck. The card got detected, serial_cs was loaded, hciattach
wasn't happy. So I switched to my laptop, which already had a working
BlueZ setup with a USB device (Debian testing/2.6.11 kernel). Not much
better.
ttyS0: detected caps 00000700 should be 00000100
ttyS0 at I/O 0x3f8 (irq = 5) is a 16C950/954
and then hciattach wouldn't work, no matter what speed I tried.
Much Googling didn't seem to turn up much. And then I found a link to:
http://www.summet.com/x31/8250_patch_CFcard.txt
I thought this would be the answer, but it turned out not to be.
However, with the addition of a:
setserial /dev/ttyS0 baud_base 912600
I can then do:
hciattach -s 912600 /dev/ttyS0 bcsp
And I have working Bluetooth. hciscan works locally and on a remote box
finds the laptop ok and I can make an rfcomm connection to my mobile
phone.
I get a:
bcsp_recv: Out-of-order packet arrived, got 1 expected 0
message, but only the once.
Hopefully this might help someone else battling with a similar card; I
couldn't find any success stories about similar ones. Now all I need to
do is try it again with the Zaurus, which it was actually bought for. :)
