Adafruit GPS not getting fix

Post by AndroTest »

I have this code:

#!/usr/bin/python3
import serial
ser = serial.Serial('/dev/ttyUSB0', 9600)
if ser.isOpen():
ser.write(str.encode('$PMTK605*31\r\n'))
response = ser.readline()
print(response)
ser.close()


I get this:
$PMTK705,AXN_2.31_3339_13101700

I want to upgrade firmware, but I can't find any Linux tool, just Windows and I don't have any Windows machine.

Any suggestions? I got GPS fix once couple days ago, but can't get fix anymore. I have the antenna attached to it as well

If you can't get a fix updating the firmware won't help so let's work on that first. Have you tried reading the data in raw format? What is the LED doing, how fast is it blinking? Are you testing it outside?
