Subject: [Bluez-users] Problem with slow Speed of Socket CF Card
Date: Sat, 29 May 2004 10:47:20 +0200	[thread overview]
Message-ID: <200405291047.20701.wolfgang@iksw-muees.de> (raw)

Hello,

I am using the Socket Communications CF Card Rev. G with the CSR chipset=20
and the bcsp protocol in my Zaurus C750 with Kernel 2.4.18.
It is working fine (thank you, guys).

hicattach opens the card with a speed of 230 KBit/s. This is the speed=20
the CSR chipset is initialized after reset. I am using PAN, and I get a=20
file transfer rate of about 150 KBit/s. With other bluetooth devices=20
(USB dongle) I get about 550-600 KBit/s.

I have asked Socket Communications if the card is limited to slow=20
baudrates, and they have answered me that this card is able to perform=20
about 730 KBit/s under ideal conditions.

Obviously, this is not possible with a serial UART and 230 KBit/s.
So there must be a speed change command, and I want to use it.

Can anybody give me some usefull advice how to proceed?=20
I am able to write/change kernel drivers, but I have no hint where to=20
start and how to get the speed change information in the bcsp protocol.

best regards
Wolfgang M=FCes
