CayenneLPPDecode

This is an Arduino Library Compatible to Decoder Cayenne Low Power Payload to Json format (ArduinoJson).

Dependences

This library uses the ArduinoJson library.

Installation

• Install the library by Importing the .zip library using either the master or one of the releases ZIP files.

Documentation

• API References:
  • CayenneLPP (Johan Stokking)
  • CayenneLPPDecode

Examples

The library comes with examples. After installing the library you need to restart the Arduino IDE before they can be found under File > Examples > CayenneLPPDecode.

Quickstart

CayenneLPP Input

lpp.addDigitalInput(1, 0);
lpp.addDigitalOutput(2, 1);
lpp.addAnalogInput(3, 1.23f);
lpp.addAnalogOutput(4, 3.45f);
lpp.addLuminosity(5, 20304);
lpp.addPresence(6, 1);
lpp.addTemperature(7, 26.5f);
lpp.addRelativeHumidity(8, 86.6f);
lpp.addAccelerometer(9, 1.234f, -1.234f, 0.567f);
lpp.addBarometricPressure(10, 1023.4f);
lpp.addGyrometer(1, -12.34f, 45.56f, 89.01f);
lpp.addGPS(1, -12.34f, 45.56f, 9.01f);
