I am currently using an Adafruit Ultimate GPS FeatherWing to get my coordinates, and im trying to display them in the Arduino IoT cloud dashboard using the map widget. What do I need to fix to be able to correctly get the gps coordinates onto the map?
// Test code for Ultimate GPS Using Hardware Serial (e.g. GPS Flora or FeatherWing)
//
// This code shows how to listen to the GPS module via polling. Best used with
// Feathers or Flora where you have hardware Serial and no interrupt
//
// Tested and works great with the Adafruit GPS FeatherWing
// ------> https://www.adafruit.com/products/3133
// or Flora GPS
// ------> https://www.adafruit.com/products/1059
// but also works with the shield, breakout
