Questions:
1. I assume the flow-graph is still active even during the OFF cycle(data is still processing through the GNU blocks)??
2. Is time.sleep() function is an appropriate way to use for OFF cycles in my model ?? If not can anyone suggest me better way to break the transmission using GNU blocks ??
3. Is there anyway to control the transmission at python level by using single or multiple flowgraph model or suggestion to implement any new block ???
Multiple flowgraph Approach :
I tried to provide a two flowgraph model for ON and OFF cycles;I switch between the two depending on the markov state.
ON cycle flow -graph:
packet modulator --------> modulator ----------> ampl -----------> usrp sink
OFF cycle flow-graph
packet modulator --------> modulator ----------> ampl ----------->null sink
4. Does my problem has anything to do with in band timestamp of packets ???
It would be great if someone guide if I'm wrong in understanding GNU Radio architecture.Thanks in advance.
