I have to rb433’s with r52ah cards. I can connect 2.4 antennas to them and scan and see a bunch of other networks, but they can not see each other. If i connect 5.7 antennas they can’t see anything.
Need more info. I assume 1 card is setup as an APbridge or you don’t have any signal for the other card to see.
what version ROS?
please show configuration of wirless
