@cek Thanks very much for your great support. All of the problems have been solved.
For the benefit of the forum, I would like to share my experience as follows:
After upgrading to INS, there may be some problems for the WIN webserver to identify the COM port . It may take more than 3~5 minutes to identify it or the COM port can not be identified. So it would be better to use it in Linux such as Ubuntu. It is very fast and stable. As long as following the instruction, it is not so difficult.
If you plan to apply the UBLOX-m9 (GPS - ZED F9P), use Ucenter to configure your ZED F9P as shown below: )
Please note the baudrate should be changed from 9600 to 115200!!!!
