Good morning,
I need to implement a double 802.15.4-802.11b transmitter that transmits
packets in asynchronous (or aperiodical) mode.
I realized a simple program where the output of the two trasmitters are added
together to generate the output stream.
Unfortunately, when one of the two transmitters ends to generate a packet,
also the other one stops. It happens ( i think! ) because there are no samples
for the adder to combine with and the forecast() method stops the execution.
By the way, I found online a similar discussion:

In order to have a countinuos output stream even when the two transmitters are
inactive, could I implement a gnuradio c++ block with the following
characteristics?
-performs a continuous production of null samples (when there are no input to
the block)
-lets the samples unchanged if there are samples at his input.
Thanks a lot,
