Thanks for your reply josh.. I only have the message socket block now.But still i get the attached error..
And,you were suggesting an amplitude < 1 which i am not aware of..can you please explain. Also,i am using a trying to transmit a message so why do i need a packet deframer? thanks.. tx_message_socket.png <http://gnuradio.4.n7.nabble.com/file/n40062/tx_message_socket.png> manjusha, * Delete this: The pad source is for hierarhical blocks. * Delete this: That message source is not related * I recommend to reduce the amplitude of the signals sent to the usrp source < 1.0 magnitude * You do not need to feed the input of the message socket block - that is for writing to the socket. You would probably connect a packet deframer from the receive chain there. Your flow graph is ready, if you write a packet into this socket, it will transmit something. the pad source is for making hierarchical blocks, you probably dont want this. There are 3 ways to get data into that packet encoder from gr extras. * A message socket block * The stream to blob block * A custom block that outputs message blobs ----- Manjusha -- View this message in context: http://gnuradio.4.n7.nabble.com/right-source-to-input-message-tp40059p40062.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
