I'm running MicroPython v1.8.6-849-fcbbfe3 on 2018-01-03; FiPy with ESP32 with a
Pytrack (pytrack_0.0.8.dfu).

GPS just returns timeout with this script

from L76GNSS import L76GNSS
from pytrack import Pytrack
import gc

py = Pytrack()
l76 = L76GNSS(py, timeout=60)
print ("Starting GPS")
while(True):
     coord = l76.coordinates(debug=True)
     print("{}".format(coord))
     gc.collect()

In flash/lib directory I have the attached py files pytrack-lib.zip
(These are not the latest ones, as the current pytrack.py using pycproc.py gave some error)

• pytrack.py
• LIS2HH12.py
• L76GNSS.py
