[Bluez-users] Unknown HCI packet type / 3CRWB6096B

[Jan Sykora]

Hello

Could anybody please give me some hints what is wrong.

I am able to establish kppp session to siemens s55 mobile and the 
connection works OK, however after a while I get messages in 
/var/log/messages

this is an out of sync H4 stream. This happens sometimes. Try to enable
flow control on your serial port.

Hi Marcel

Unfortunately it did not help. I have now

kppp with CRTSCTS flow control and

hciattach /dev/ttyS17 any 115200 flow

and I am getting the same error messages.

Do you have any other hints? Thanks.

regards

Jan

the best would to switch the CSR chip into BCSP mode and us this. I
don't own the version 3.0 of that card, so I can't do any tests.
