I have several pairs of 3dr and clone 433MHz radios which were all working fine three days ago. They are all recognised using the standalone 3dr SiK radio software and when connected through that software the RSSI is ~180+ . The issue comes when I try to connect in MP when everything just times out. I have tried everything I know, including reinstalling MP and yet there is still no connection. I have tried this with both a 3DR Pixhawk and a drotek dropix (different cables and connectors)controllers but the same problem persists.
Any suggestions for what to try next would be greatly appreciated.
Many thanks in anticipation of your help.
