Re: [Discuss-gnuradio] Muliple top_block()

[smith mark]

Hi

Thanks for the reply. I used tb1.start() and tb2.run() and I think that is working. The two blocks don't have connections with each other.

 The flow is like:

tb1=gr.top_block()

1. tb1.start()

2. Some variable declaration...

Repeat step 3 and 4, five times 

3. A function that creates tb2 and runs it and return the result

     --- tb2=gr.top_block()

     --- vector source--->convolution coding----->destination

     --- tb2.run()

     --- return destination.data()

4. send the result to the tb1 for processing

5 . tb1.wait()

 

As far as the result is concerned it seems right. But, I want to know that whether this type of thing is conceptually right or not ?? 

I read that there must be only one top_block(). Please guide me in this..

Regards

Smith
