Get the NMEA sentence using getLatestNMEAGPxxx (GGA, VTG, RMC, ZDA)

|
||||
basically do whatever you want with this code.
|
||||
|
||||
This example shows how to turn on/off the NMEA sentences being output over I2C.
|
||||
It then demonstrates how to use the new getLatestNMEAGPxxx function to retrieve the latest GPGGA message.
|
||||
getLatestNMEAGPxxx returns immediately - it is not blocking.
|
||||
It returns:
|
||||
0 if no data is available
|
||||
1 if the data is valid but is stale (you have read it before)
|
||||
2 if the data is valid and fresh
|
||||
|
||||
If the module is using multiple GNSS constellations, the GGA message will be prefixed with Talker ID "GN" instead of "GP".
|
||||
The library includes getLatestNMEAGNxxx functions too.
|
||||
This example shows how to use both functions - and how to change the Talker ID so the GNGGA messages become GPGGA etc..

Hardware Connections:
|

Plug a Qwiic cable into the GNSS and a RedBoard
|
||||
If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)

||||
Open the serial monitor at 115200 baud to see the output
