Unable to connect Survey123 to Trimble R1 receiver on a Surfrace Pro2 (windows 8). Survey 123 is functioning and the R1 receiver (GNSS Status Utility software) is functioning but I am unable to get the two programs to interact. The Surface Pro 2 does not have an internal GPS, is this the problem? I have had success using Survey 123 on a mobile device attached to the R1 receiver. However need to have it work on the Suface Pro. Fieldwork will be outside of any cellular network. My R1 distributor was unable to solve the issue. Thank you for your help!
