I have a project that involves tracking multiple units and measure their movement (telemetry). I updated the firmware on my RFD900+ units, I have 3 of them. I want them to talk to the groundstation and provide telemetry feedback to mission planner, where I can see all units at the same time. After flashing the multi point firmware, everything went fine but now my radios are flashing green and will not link together. How can I fix this so 2 radios can talk to my ground station?
