[Discuss-gnuradio] minimum number of packets usrp can receive?

[Omer Ihsan]

i am using the RFX-2400 with usrp-1

i would like to know what is the minimum amount of data/ minimum number of packets that the usrp can receive.
i used the benchmark_rx file and changed the default packet size to 10 bytes. by using the --from-file option and sending only 1 packet (10 bytes) of data i was unable to receive anything. only when the data was about 4 packets was i able to receive. i changed the packet size to different values but still couldn`t receive a single packet. i am transmitting at 500kb, gmsk, and the --discontinuous option enabled. is this a limitation of the usrp or am i missing something?

secondly can anyone tell as to how many bits or bytes a single byte of data is converted to during transmission? i mean if i had 1 byte to transmit what would i get at the receiver say before the correlator.
