Re: [Bluez-devel] Hardware error

[mike <mikelee@avantwave.com>]

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
