Hi Xianning,
Is that because I purchased and used AU version?
I tried out either GPS antenna (RFsister) plug into GNSS port or i purchased grove GPS plug into UART port, both cannot get GPS location. Btw I tested at school lab, not outside. The coding and library for GNSS test I tried Espruino and Arduino IDE with library that Seeed studio provided on wiki. Is there some way that I can directly liaise with you?
Thanks.
Regards,
Yiqian
