Conexion bluetooth nmea con fielgenius no conecta

ya he hecho todo seguido todos los tutoriales, pero no logrado conectar por bluetooth mi reach rs+ con mi tableta dell vebue win 8,1 a travez de fieldgenius, que funciona muy bien con un trimble.

I am having the OPPOSITE trouble with a Trimble NOMAD 6G data collector. But works fine on my Windows 10 surface devices and desktop. This was after FIRMWARE 26 update yesterday. Worked fine on all before that. It PAIRS. But will not stay connected.

Edit:

actualiza tu window a 10 para que te funcione
