Tiny RTK Base: No RTCM3 Message via UART

Hi,
I have my base station set up as following addressManual configuration of the base module. I am using Survey-In mode and the survey successfully. After that can not see any RTCM3 message, and the fix mode is still 3D, which expected to be TIME.



And i found the same problem in this forum, the solution is setting the PRT change the Target into USB.
but my in project the corrections must be sent through UART, can anyone help me?

thanks for your help in advance.
