Arduino SigFox温度数据问题

Question

有人能帮我处理这个西格福克斯的设置吗？我做错了什么？

我唯一想要实现的就是将内部温度和状态发布到sigfox后端。每15分钟公布一次数据。配置了一封来自服务部门的电子邮件，显示以摄氏度为单位的温度。

张贴到后端是有效的。然而，电子邮件消息和数据似乎不一致。在调试模式下运行代码时。以摄氏度表示温度是正确的。

有手册吗？

代码Arduino MKR FOX 1200

typedef struct __attribute__ ((packed)) sigfox_message {
  int16_t moduleTemperature;
  uint8_t lastMessageStatus;
} SigfoxMessage;

// stub for message which will be sent
SigfoxMessage msg;

void setup() {

    // Wait for the serial
    Serial.begin(115200);

    // Something is really wrong, try rebooting
    // Reboot is useful if we are powering the board using an unreliable power source
    // (eg. solar panels or other energy harvesting methods)
    reboot();
  }

  //Send module to standby until we need to send a message
  SigFox.end();

  if (oneshot == true) {
    // Enable debug prints and LED indication if we are testing

  SigFox.begin();
  // Wait at least 30ms after first configuration (100ms before)
  delay(100);

  // We can only read the module temperature before SigFox.end()
  float temperature = SigFox.internalTemperature();
  msg.moduleTemperature = convertoFloatToInt16(temperature, 60, -60);

  SigFox.beginPacket();
  SigFox.write((uint8_t*)&msg, 12);

  msg.lastMessageStatus = SigFox.endPacket();

  if (oneshot == true) {
    Serial.println("Status: " + String(msg.lastMessageStatus));
  }

  SigFox.end();

  if (oneshot == true) {
    // spin forever, so we can test that the backend is behaving correctly
    while (1) {}

  //Sleep for 15 minutes
  LowPower.sleep(1 * 60 * 1000);

Conversion.h

#define UINT16_t_MAX  65536
#define INT16_t_MAX   UINT16_t_MAX/2

int16_t convertoFloatToInt16(float value, long max, long min) {
  float conversionFactor = (float) (INT16_t_MAX) / (float)(max - min);
  return (int16_t)(value * conversionFactor);
}

uint16_t convertoFloatToUInt16(float value, long max, long min = 0) {
  float conversionFactor = (float) (UINT16_t_MAX) / (float)(max - min);
  return (uint16_t)(value * conversionFactor);
}

设置Sigfox后端-电子邮件回调

​

Answer 1

使用当前的convertoFloatToInt16，不可能直接从Sigfox后端在电子邮件中显示真实温度。

您需要使用从Sigfox后端回调到实现convertoFloatToUInt16的服务器，然后发送电子邮件，或者以Sigfox后端可以本地解码的格式发送温度(32位浮点数可能是最合适的)。
