Hi all
I have the next block:
[image: Imágenes integradas 1]
This block just receive signal for one of the two ports at the same time.
In this way, for example if it receives in the IN0, in the IN1 there's
nothing. Depending on the parameter Initial Standard I select which input
must pass to the output, that as supposed, is the input in which I have
signal.
Then, i wrote the next forecast() method.
void forecast(int noutput_items, gr_vector_int &ninput_items_required){
if(d_st_aux == 0){
ninput_items_required[0] = 0;
ninput_items_required[1] = noutput_items;//Tx Xbee
}else{
ninput_items_required[0] = noutput_items;//Tx Wifi
ninput_items_required[1] = 0;
}
}
In that way I just take the input that has signal, and that works perfectly.
The problem is when, through the third input, I send a command in order to
change the input that I want to read. That's done by way of re-writing the
value of *d_st_aux*, it occurs in real time. For this case, I would need
that forecast method changes in real time, the ninput_items_required, but
it doesn't work. I think the block is just calling the forecast method when
it starts, but I need to call forecast in real time.
How can I do that?
Thanks in advance.
Best regards,
Cristian
