Re: why udp source and sink not work effieciny in gnuradio?
Hi, my guess would be that the file source and UDP sink are much faster than the UDP source and QT GUI Sink. As UDP is "fire and forget", the "transmitter" may be pushing more data over the network than the QT GUI Sink can handle. To test this, you can replace the QT GUI Sink with a NULL sink, which just deletes the data. Or you can add a throttle block after the File Source to reduce the data rate.

Re: why udp source and sink not work effieciny in gnuradio?
Exactly this. By choosing UDP, you chose to drop packets when they are not handled in time. So, this is working 100% as expected.

Re: Request for help with Comprehensive RFID module in GNU Radio on Linux
Hi stackprogrammer, pick one, and do a bit more research! The technologies involved are pretty different. Then research based on that! "RFID" is a wide topic, and as you can imagine, getting data out of an animal identification chip with a reader held onto the chip works differently than reading your credit card, and works differently than scanning pallets full of tagged goods when unloading them.
