Datasheet

When the code runs it will print a message every second to the REPL, either an update that it's still waiting for a GPS

fix:

# Main loop runs forever printing the location, etc. every second.

last_print = time.monotonic()

while True:

# Make sure to call gps.update() every loop iteration and at least twice

# as fast as data comes from the GPS unit (usually every second).

# This returns a bool that's true if it parsed new data (you can ignore it

# though if you don't care and instead look at the has_fix property).

gps.update()

# Every second print out current location details if there's a fix.

current = time.monotonic()

if current - last_print >= 1.0:

last_print = current

if not gps.has_fix:

# Try again if we don't have a fix yet.

print('Waiting for fix...')

continue

# We have a fix! (gps.has_fix is true)

# Print out details about the fix like location, date, etc.

print('=' * 40) # Print a separator line.
