Question

我无法从以太网Shiled到Cosm的Arduino Mega上传数据。我尝试了一个教程示例（DatastreamUpload.ino）。我使用了Cosm在注册时给我的API密钥和Feed ID，并将init()函数更改为使用静态IP地址，如下所示：

    byte mac[] = {0x90, 0xA2, 0xDA, 0x0D, 0xD3, 0x45 };
    IPAddress ip(192,168,0, 110);
    IPAddress gateway(192,168,0, 1);
    IPAddress subnet(255, 255, 255, 0);

然后：

    Ethernet.begin(mac, ip, gateway, subnet);

以下是串行监视器的输出：

Read sensor value 452.00
Uploading it to Cosm
cosmclient.put returned -1

Read sensor value 451.00
Uploading it to Cosm
cosmclient.put returned -1

Read sensor value 378.00
Uploading it to Cosm
cosmclient.put returned -3

Read sensor value 352.00
Uploading it to Cosm
cosmclient.put returned -3

有人有解决方案吗？

目前缺乏关于此的文档，需要查看源代码才能找到答案。这些错误代码在HttpClient.h中定义如下：

// The end of the headers has been reached.  This consumes the '\n'
static const int HTTP_SUCCESS =0;
// Could not connect to the server
static const int HTTP_ERROR_CONNECTION_FAILED =-1;
// This call was made when the HttpClient class wasn't expecting it
// to be called.  Usually indicates your code is using the class
// incorrectly
static const int HTTP_ERROR_API =-2;
// Spent too long waiting for a reply
static const int HTTP_ERROR_TIMED_OUT =-3;
// The response from the server is invalid, is it definitely an HTTP
// server?
static const int HTTP_ERROR_INVALID_RESPONSE =-4;

不出所料，你链接到的人看起来100％犹太教，我很难看到与我用过的东西不同的东西。

作为预防措施，我会提出 int ret = 0; 在循环开始时

我发现你只有一个传感器，但建议你一丝不苟地将它识别为sensorId0

我有一个缓冲区

const int bufferSize = 100; char bufferValue[bufferSize]; CosmDatastream datastreams[] = { CosmDatastream(sensorId0, strlen(sensorId0), DATASTREAM_FLOAT),

整瓶已于去年10月在cosm论坛上发布。

我不使用那个ip，网关和子网的东西。这可能会让水变得混乱。
