无法使用Arduino GSM屏蔽上传Xively Feed

标签: arduino gsm xively

我试图通过Arduino GSM盾牌上传一个带有Arduino的Xively Feed。

Xively没有公布Arduino GSM屏蔽的任何具体示例。我尝试使用Arduino GSM Pachube客户端库在“xively.com”中更改“pachube.com”,但它不起作用。似乎我的GSM屏蔽能够连接但不能将数据放到服务器上。

在我的例子中,我创建了一个名为“Arduino GSM”的设备,只有一个名为“sensor1”的通道。在请求日志中,我无法读取任何传入的请求,尽管串行监视器显示与服务器的连接发生。

这是我尝试过的代码:

    // Original GSM Pachube client modified for Xively
    // Changes: pachube.com -> xively.com
    // inserted APIKEY, FEEDID, USERAGENT
    // inserted GPRS_APN, login, password

    /*GSM Pachube client

     This sketch connects an analog sensor to Pachube (http://www.pachube.com)
     using a Telefonica GSM/GPRS shield.

     This example has been updated to use version 2.0 of the Pachube.com API. 
     To make it work, create a feed with a datastream, and give it the ID
     sensor1. Or change the code below to match your feed.

     Circuit:
     * Analog sensor attached to analog in 0
     * GSM shield attached to an Arduino
     * SIM card with a data plan

     created 4 March 2012
     by Tom Igoe
     and adapted for GSM shield by David Del Peral

     This code is in the public domain.
