Fails reliably at its job of providing connection
It is difficult to set up a new device and requires coordinate system codes and knowledge of your local satellites by coded name. Switching R2 and DA2 devices between users and reconnecting to a different mobile device is accomplished successfully by only the most skilled users and never on the first try. Constantly dropping connection and opening and closing Mobile Manager and Field maps should be expected. The amount of glitchy button pushing between the two apps is certainly not what developers had in mind and is an indication of its weakness in providing communication between Field Maps and your GNSS. It is a requirement for the two devices mentioned above so if you have to use these devices, it works best on a set up where the same iPad and user are constantly connected to the same receiver. When firmware and other subscriptions expire, plan out a few weeks of reconnecting to Mobile Manager and your GNSS as if you had repurchased your units anew, or purchase a unit that does not run with Mobile Manager. Our vendor works with us regularly to trouubleshoot and has the same set of challenges each time, so this is really not an issue of user error.
