Ug-353 Gps Driver Apr 2026

Now $GPGGA sentences appeared cleanly.

sudo gpsd /dev/ttyAMA5 -F /var/run/gpsd.sock But cgps showed a blank screen. Zero satellites. Sky was clear. ug-353 gps driver

Marta checked the datasheet. UG-353 defaults to 9600 baud , but the Linux kernel expected 115200 for the UART. She fixed the stty settings: Now $GPGGA sentences appeared cleanly

gpsd: gpsd: command socket at /var/run/gpsd.sock gpsd: device /dev/ttyAMA5 is a UG-353 (NMEA) gpsd: no fix: no GPS signal But the UG-353 was outputting valid GGA sentences with a 3D fix. Why ignore them? She realized the UG-353 outputs , but gpsd ’s autobaud logic was misreading the sentence interval as corrupted data. She forced the baud rate and enabled raw NMEA mode : ug-353 gps driver
