Exactly.

What I do is just offering  a tool. Those example is just a simple
verification.

I think the tool and hackrf do have the full ability, because hackrf can
switch from channel to channel very quickly (less than several us? Maybe
Ossmann can give some number?).

You may define a packet sequence with each packet starting with different
channel number as you want, then hackrf will transmit a hopping channel
packet sequence.
