Bridge repeaters: Which firmware?

[dreieck]

Ahoj!,

I just registered here because I wanted to ask a question regarding the bridging repeaters with two radios that are mentioned at meshwiki.nl/wiki/The_switch:

A bridge is a node with two radios: one on SF8 and one on SF7. Messages received on one frequency are forwarded on the other.

Which firmware do they use/ how are they built?

This is very interesting for a backhaul net or to build point-to-point long distance links with directional antennas as well.

Regards!
