GPS Module WPI430 - no communication possible

Hello, I bought 2 of this GPS-Modules (WPI430) and cannot communicate with both modules. Not via USB and not via the serial port.
I tested it with Arduino Mega 2560, Arduino Giga R1 and via USB with m-center and s-center from ublox.
I have 2 of the older modules (VMA430) and they are working fine.

The modules seems working - the 1pps works. But no communication.

What is the difference between this modules? Is it possible they are both defect with the same damage?

@hello @gerhard_r

Normally, there is no difference between the WPI430 and VMA430. It is only a brand name change. If both do not work as described in the manual:https://cdn.velleman.eu/downloads/25/wpi430a4v01.pdf & GitHub - Velleman/VMA430_GPS_Module: Library for working with the VMA430 - GPS Module U-BLOX NEO-7M, may indeed indicate malfunction.

Should it not work, you can return it to shop where purchased to start RMA procedure.
