Tried both, and it didn’t work. I took logs and sniffed the UART to help with debugging. My GPS responds to metr queries with
EXT CORE 4.04 (7f89f7)00190000ROM BASE 0x118B2060FWVER=SPG 4.04PROTVER=32.01M
OD=NEO-M9NGPS;GLO;GAL;BDSSBAS;QZSSz$GNTXT,01,01,00,txbuf alloc*61
And it also constantly streams a bunch of NMEA data with coordinates, velocity and such
I sent the logs and sniffed GPS uart hex data into your support email. Hopefully this helps. Thanks.
