Re: [Discuss-gnuradio] message_source repeatly transmit msg 10times

2011-03-06 Thread Yan Nie
I also tried msgq.flush() to delete all of the data in the queue as soon the data is inserted to the message queue. This approach allows the data repeatly transmitted in various times, ranging from once to 10 times.   I explored some of the gnuradio examples which use send_pkt to transmit data.

If you post your code it would be easier to help. One guess is that there's something going wrong with the packing/unpacking. I think the modulation and demodulation blocks assume you have one symbol per byte which would mean for DBPSK only one bit in each byte is used. Make sure you have approp
