Hey, The Quectel EC25 exposes 4 TTYs and 1 QMI/wwan pair. ttyUSB2 and ttyUSB3 are AT-capable ports; does anyone know what ttyUSB0 and ttyUSB1 are? E.g. is ttyUSB0 the GPS NMEA port? Also, does anyone know which AT commands should be issued to start/stop the GPS engine in the module? Cheers! -- Aleksander https://aleksander.es
