Arduino Arduino SigFox for MKRFox1200 - read()用法及代码示例


说明

读取传入的SigFox 数据。 read() 继承自 Stream 实用程序类。

用法

SigFox.read()

参数

None

返回

传入 SigFox 数据的第一个字节可用(如果没有可用数据,则为 -1) - int

示例

/*
  SigFox First Configuration

  This sketch demonstrates the usage of MKRFox1200 SigFox module.
  Since the board is designed with low power in mind, it depends directly on ArduinoLowPower library

  This example code is in the public domain.

#include <SigFox.h>
#include <ArduinoLowPower.h>

void setup() {
  Serial.begin(9600);

  // Uncomment this line and comment begin() if you are working with a custom board
  //if (!SigFox.begin(SPI1, 30, 31, 33, 28, LED_BUILTIN)) {
  if (!SigFox.begin()) {
    Serial.println("Shield error or not present!");

  // Comment this line when shipping your project :)
