WebAug 13, 2024 · Matching port speed (using stty) and GPS speed (using gpsinit) works up to 115,200, but only until power cycle, when the GPS retains the new speed but /dev/ttyAMA1 goes back to default. And thus gpsd.service cannot operate at any baud rate but 9600. Any hints why the gpsd auto baud isn’t functional, and any workaround to use a faster baud rate?
