in the past, I was able to connect my GNSS receiver (Trimble GeoExplorer 2008 GeoXT) with a mobile phone (like Nokia, not a smartphone) via Bluetooth for NTRIP corrections. Actually, I'm not able to do it anymore with any Android smartphone (like a Huawei P9 lite or a OnePlus 2). More precisely, I can connect the GNSS receiver to the Android smartphone with the WiFI, but not with the Bluetooth protocol. The GNSS receiver and the android smartphone seem to be paired but they are really not connected.
Do you have any suggestion?
Thanks in advance
