Re: [Discuss-gnuradio] Question Regarding GMSK2 examples

Eric,

Thanks for pointing out rx_callback to me.  I can't believe I missed that
function when I was going through the example.

As a related question, does rx_callback only exist if the packet is received
properly (i.e. without errors)?

Regards,
Elaine
