Hi Cesar, I strongly recommend you use something like the Adafruit GPS library to read from the GPS chip. (This will mean you won't have to do all the string parsing yourself.)
The attached code is a sketch that should work for Arduino (actually tested it using a Teensy) with a GPS attached to RX1/TX1. It will turn on the GPS, get updates at 1Hz, and once it has a fix will convert the lat/lng into a plus code and print it to the serial monitor: Time: 10:56:5.0 Date: 27/2/2019 Fix: 1 quality: 1 Location: 4721.9287N, 831.4218E Location (in degrees, works with Google Maps): 47.36547852, 8.52369690 *Plus code: 8FVC9G8F+5F* Speed (knots): 9.55 Angle: 256.43 Altitude: 428.00 Satellites: 3 HDOP: 3.01 The only bit of code you should need is the encodePlusCode() function. (This is a new implementation that I like because it's super short.) Let us know how you get on!
