Xively Demo with WizFi250

Let me introduce the “Xively server and WizFi250 application note.

In order to Test, the customer should make a Xively ID and acquire Channel and API key.

(For more information about the Xively, Please check the Youtube or Google)

This test environment is as below

•Feed ID : 1805123826

•X-ApiKey : H3lr9T1As7ADOfpXCvg8fdcUYC3wX39tXVUBGAIKvouibJnM

•Channel : Demo

Test Procedure

(A) The local data save to Xively Cloud

(B) The Data receive form Xively Cloud

Let’s start Demo

(A) Request Raw Data: the temporary 4 byte data save to Xively cloud

PUT /v2/feeds/1805123826/datastreams/Demo HTTP/1.1\r\n

Host: api.xively.com\r\n

X-ApiKey: H3lr9T1As7ADOfpXCvg8fdcUYC3wX39tXVUBGAIKvouibJnM\r\n

Content-Length:81\r\n

\r\n

{\r\n

"id": "Demo",\r\n

"tags": [],\r\n

"unit": {},\r\n

"current_value": "4"\r\n

}\r\n

\r\n

(Total 236 Byte)

(B) Request Raw Data : The Data receive form Xively cloud

GET /v2/feeds/1805123826/datastreams/Demo HTTP/1.1\r\n

Host: api.xively.com\r\n

X-ApiKey: H3lr9T1As7ADOfpXCvg8fdcUYC3wX39tXVUBGAIKvouibJnM\r\n

\r\n

(Total 136 Byte)

In order to use Xively server communication, you should associate with AP.

(It is depends on your test AP environment. Therefore we omission this parts.

Please refer to as below link

(“Examples - Association & Disassociation” part)

u Step #1: Obtain the Xively API sever IP

AT+FDNS=api.xively.com,3000

64.94.18.120

[OK]

u Step #2: Access the the Xively API sever, and then send the Request command that save the value “4” in the Channel Demo

AT+SCON=O,TCN,64.94.18.120,80,,0

[OK]

[CONNECT 0]

AT+SSEND=PUT /v2/feeds/1805123826/datastreams/Demo HTTP/1.1\r\n

Host: api.xively.com\r\n

X-ApiKey: H3lr9T1As7ADOfpXCvg8fdcUYC3wX39tXVUBGAIKvouibJnM\r\n

\r\n

{\r\n

"id": "Demo",\r\n

"tags": [],\r\n

"unit": {},\r\n

"current_value": "4"\r\n

}\r\n

\r\n

[OK]

If you send correctly a data, you should be receive from the Xively API server

{0,64.94.18.120,80,251}HTTP/1.1 200 OK

X-Request-Id: 65d5981411f55879f102ebd8df82e4c2978cfac1

Cache-Control: max-age=0

Vary: Accept-Encoding

u STEP #3: Close the connection the Xveily API Sever

AT+SMGMT=ALL

[DISCONNECT 0]

[OK]

when you see the Feed Channel, you should find a data to apply real time in Xively API server.

https://xively.com/feeds/1805123826

Next, we’re trying to get the data from Xively cloud server.

Refer to as below command

AT+SCON=O,TCN,64.94.18.120,80,,0

[OK]

[CONNECT 0]

AT+SSEND= GET /v2/feeds/1805123826/datastreams/Demo HTTP/1.1\r\n
