Thanks for your help Kyeong, file transfer completed successfully, the periodic error still occurs but is not critical. I want to transmit live data (serial port data) instead of files. Is it possible with python block or another block?

GNU Radio gave you a warning about this: >>> Warning: This flow graph contains a throttle block and another rate limiting block, e.g. a hardware source or sink. This is usually undesired. Consider removing the throttle block. Throttle block is used to intentionally slow down the execution of the flowgraph, for simulation purposes. It causes data drops if used with real hardware.
