Gravity GNSS Positioning Module - UART doesn't work

I bought a module like in the title. I just wanted to read UART data and connect the module to the computer via UART → USB converter. I didn't get any data from the module. The color of the diode is red/green.
RX config from the PC program is like the below:
Do I'm making something wrong or module is broken?
Thanks for the help and tips :)
I WAS HAVING A PROBLEM USING IT IN ESP32-WROOM-32
it ONLY SHOWS “NO DEVICES”
jayrome The module does not actively report data. You need to send the appropriate command to get the data.See the wiki for details:https://wiki.dfrobot.com/SKU_TEL0157_Gravity_GNSS_Positioning_Module
Xiao Does somebody use this module in practice? Do you have some ideas? Thanks for help :)
terradyne Hello,
In the datasheet of this module there is an information to use BD = 9600. I chosen the same value but I didn't get anything from TX pin.
terradyne Make sure that the baud rate settings on both the module and your UART to USB converter match.
