normally when it says hardware error then it is a hardware error. Since
this is a BlueCore chip you might get more information with specific
vendor commands, but don't ask me how. I never needed this before.

Marcel

[Bluez-devel] Hardware error

[mike]

Dear All
    When i try to send file though bluetooth, there is a hardware error 
in hcidump. I am using serial dongle with CSR BC02 external chip set, 
hci firmware ver 18.1.  And then both side will halt at the bluetooth 
read/write system call. I want to find out is it the problem from my 
hardware or anything else. Do anyone have ideas?

Hi Mike,

a possible cause of a hardware error is an Uart overrun. Do you have
hardware handshake enabled ??

Ciao,

Peter

If you find out what the parameter was to the hardware error event, you
might get a clue as to what was going on.

You can look up the hardware error codes for CSR chips in the document
HQ Commands (bcore-sp-003Pc) on the CSR support web site if you have
access (www.csrsupport.com).

The most common hardware error emitted by CSR devices running the H4
UART host transport is 0xfe. This indicates that the chip has lost HCI
synchronisation with the host. This is caused either by the host sending
invalid data or because of corruption of the UART traffic on the wire.

Unfortunately, the H4 UART protocol does not support a proper error
recovery procedure. The only option, once this error has occurred, is
to issue an HCI_Reset which will, of course, tear down all existing
links.

Re: [Bluez-devel] Hardware error

Dear Steven
    Thanks for information, I have checked that the error code is 0xfe. 
Actually, i do not use cable as i am using 921600 baud rate, cable 
increase the error rate. 
    I am trying to modify the coding.
 
    Anyways, thanks a lot
best regard
Mike,Lee
