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,
