Hi Felipe,
There were some characters missing in the other end of the communication. As you suggested, I used more accurate external clock and able to get 921600bps correctly. I am also open to other ways to increase speed even more. Is there any implementation of USB driver in KW36? Just as a side note, I can not use the wireless solution so the data needs to be transferred through the USB cable. Is there any other suggestion you could give for higher throughput?
Best regards,
Ayturk
