We have a Trimble TDC650 and can not get it to fill in the GNSS metadata fields in Field Maps for points. The GNSS fields were added through ArcGIS Pro. The TDC650 has an Integrated receiver, but when you look at the "Position source type" field it fills in External GNSS Receiver and leaves many others blank. We have tried it with Location profiles of both SBAS (offline) and RTK (NYSNet online) and its the same result. Are we missing another setting somewhere?
