Hi,

I believe that you are using a serial port connection. This error might happen if the data send failed for some reason. What USB to serial port model you are using?

Hi,

FTDI buffer size is 64 bytes and your data should be without problems to the buffer. How often this is happening? This is now tried with FTDI chipset and it works without any problems. What is your Android version?
