Ok, after manually setting MANY config options on in ucenter’s advanced config, and futzing with the XBEE’s, and finding an ntrip server that spits out the MSM7 messges, I finally have sub-meter accuracies, both in 2D and 3D. Woohoo. The XBEE’s are communicating with each other and their blue LED’s go blinkety-blinkety together. Woohoo. So, the last inch is — rover is not using any of the readings from base. What else do i need to turn on, please? I’ve searched advanced config for possible messages missing but I just haven’t found the (probably obvious) change needed. Any ideas? Help, please, for this last little leg of this hair-pulling journey.
