thanks to everyone in this thread/openag and RTKonnect. I can confirm that RTKbase will work with Trimble 372.
ZED-F9P → RTKbase → RTK2go → Lefebure NTRIP client(android phone) → RTKonnect(bluetooth) → Trimble 372
372 firmware 8.3
RTKbase version 2.2.0
survey/post process base accurate to 3mm
**Note: the 372 takes about 10 minutes to calculate RTK. you will only have DGPS until then.
