Extended Low Power Payload for Arduino

This library allows you to encode and decode light-weight payloads on an Arduino. XLPP payload format is useful for sending IoT data over a low bandwidth network like LoRaWAN. It is an extended version of Cayenne Low Power Payload.

Example

Here is a quick example showing how to encode a temperature, a voltage and a string over XLPP.

#include <xlpp.h>

void setup()
{
  Serial.begin(38400);
}

XLPP xlpp(120);

void loop(void)
{
  // Create xlpp payload
  xlpp.reset();
  xlpp.addTemperature(1, 90.0); // °C
  xlpp.addVoltage(2, 2); // Volts
  xlpp.addString(3, "test");

  // Display and use payload
  for (int i = 0; i < xlpp.len ; i++) Serial.print( xlpp.buf[i] , HEX);
