QuecGnss Init returns -1

I am currently working on utilizing the GNSS feature in the EC200UEUAA-N05-SGNSA module, following the official documentation provided on the QuecPython site. However, I encountered an issue where the quecgnss.init() function returns -1, and the initialization fails. I am using this firmware version:
QPY_OCPU_BETA0001_EC200U_EUAA_FW
I have made a custom board.

Hi,
Could you flash the standard version firmware to correctly open GNSS?

I downloaded this firmware version but there is no REPL port.

Can you forward the version in which the quec GNSS might work. I did tried with several other versions as well like:
EC200UEUAAR05A01M08_BTLVGL_OCPU_QPY_BETA0122

same result
