Satoru Yoshida / Mbed 2 deprecated Fetch_IEEE1888_Storage

fetch last data from IEEE1888 (FIAP) Storage.

Dependencies:   EthernetInterface Fiap HTTPClientForFIAP mbed-rtos mbed spxml

Fork of temp_FIAP_fetch by Yasushi TAUCHI

This program fetches last data from FIAP storage with IEEE1888 format.

Currently, You can confirm the data in console when FIAP_DEBUG_MODE is set to true.

Note: You should locate storage.txt into mbed memory at least before using this program. The storage.txt contains storage url, see example at IEEE1888_MULTI_SENSOR_GW/main.h .

And you should define FIAP_DEBUG_MODE and other constants in Fetch_IEEE1888_Storage/main.h file.

You can launch an AMI ( Amazon Machine Image ) on Amazon Web Service ( http://aws.amazon.com/ ) as the FIAP storage. The AMI is named as "IEEE1888 Storage", registered at Tokyo region.

If You need more information about the AMI, see http://d.hatena.ne.jp/satoruyoshida/20130210/1360508112 .

from here, in Japanese. このプログラムは IEEE1888 形式で FIAP Storage からデータを取得する例です。 現在、その値は FIAP_DEBUG_MODE を true に設定するとコンソールで確認できます。

このプログラムを使用する前に、少なくとも FIAP Storage の url を記載した sotrage.txt をメモリに格納しておく必要があります。 url の例は、 IEEE1888_MULTI_SENSOR_GW の main.h ファイルにあります。

FIAP_DEBUG_MODE およびその他の定数は Fetch_IEEE1888_Storage/main.h に存在します。

Amazon Web Service に用意した AMI を利用して FIAP Storage を起動することができます。IEEE1888 Storage という名前の公開 AMI です。

この AMI について詳しくは、http://d.hatena.ne.jp/satoruyoshida/20130210/1360508112 をご覧ください。
