I use a Matrice 210rtk with the D-RTK 2 Basestation. Had no troubles working both last year, come out of winter and go to use the system this year and its not working with the updates I reverted back updates and its still not working. The system is fine when it is just the Matrice out flying, when I try and hook up and use the basestation it keeps connecting and disconnecting. I have linked both the basestation and the controller multiple times, the basestation is running in mode 4 like it needs to be for the 210rtk to work. Yet I cannot get it to stay connected.

clarification: it keeps connecting and disconnecting my controller while the basestation stays connected to the aircraft

On the Matrice 210 RTK v1 that progressed until it finally became Yellow flashing lights with no Flight controller number and no battery information. Seems to be a Flight controller board problem. Have your Dealer chek it out.
