Exercise 9: GPS receiver

Introduction

Line: 17 to 17

First save a series of NMEA sentences on a file. Transfer the file to the PC and have them interpreted by the micropyGPS parser in the same fashion as the test_micropyGPS.py does. You should get a result similar to this log.

After that you may try to interpret the messages directly on the ESP32as they come in. The microGPS parser is already included in your MicroPython firmware.

Exercise 4: as_GPS

Peter Hinch has written an asynchronous GPS driver with a parser based on micropyGPS. The driver is already installed in your MicroPython binary. Use this driver to extract the information of exercise 3.

The documentation of as_GPS cant be found at https://github.com/peterhinch/micropython-async/blob/master/v3/docs/GPS.md
