Increase CC2531 USB sniffers range?

[rucanunes]

I have two CC2531 USB sniffers, one is flashed with the router firmware and the other with normal firmware.

And I have 4 SNZB-02 that I would like to bind to make them connect to HA (the ones that are further away.

I tried to connect the CC2531 USB sniffer with the router firmware to HA but with no luck.
Is there a way to increase the range of these devices? I'm talking about 20m to 30m...

Maybe bind them? How?
