    Hi, Saeed,

    fill confused by your answer.

    I found this:
    https://www.codico.com/shop/media/datasheets/Quectel_EC25_Mini_PCIe_Hardware_Design_V1.0.pdf

    page 32, bottom:

    EC25 Mini PCIe GNSS engine is switched off by default. You must switch on it by AT command. Please
    refer to document [3] for more details about GNSS engine technology and configurations. The GNSS
    engine should use a passive antenna.

    Could you pls comment?

    Hi Saeed, answer
    “You can use Passive Antenna with EC25. It is configured for active antenna.” is even more confusing.
    So, passive antenna should be used, right?

    Thanks
