It had looked like the ComPort was going to work, but uninstalling, rolling back, the correct driver just can’t be found. Tried a Dell driver for U-blox and the U-blox driver.
The Windows driver (2006 v 10.0.18362.1) works in U-Center, but there is a serial port error in other applications, such as AOG and Lefebure NTRIP Client as seen below.
After another couple of hours deleting, rebooting, roll back, etc. The place where I am leaving it is with USB Serial Device COM3, driver v 10.0.18362.1 which creates a runtime error, as above.
Thanks for your help, Alan!! What driver is your system using?
I had problems with AOG not connecting to my u-blox M8P and tried several drivers. Not long ago I discovered a driver on the u-blox site that I didn’t recall seeing before and tried it. It very consistently allows AOG to connect to my M8P. It might be worth a try. Search under Support/Product Resources for UBX-GNSS-CDC-ACM-windows_Driver_(UBX-drv-v1.2.0.8).exe.zip
The driver that seems to work with the M8P is
u-blox GNSS Receiver, 7/3/2013
V. 1.2.0.8
Using a ground plane and the antenna hanging out the window facing south, with internet corrections from a CORS about 12km away, I am getting (only) a FLOAT as viewed in RTKNAVI.
