How to debug Teseo liv3F RF or liv3F configuration issue, I am using a TESEO liv3F in my design, connected by uart with my stm32L0, the communication works but the system doesn't find any satellites. How can I debug this issue by using the UART com ?

[Kprac.1]

The Teseo's firmware hasn't changed (factory's version). The RF design is the same has the strkt01 design, but my board doesn't find any satellites, GPS and Galileo are activated, I used a GNS1A1 board with the same antenna, I set GPS and Galileo constellation and the GNS1A1 board find more than 15 satellites around me. How can I use the UArt communication to debug my issue ?

Thanks
