arduino - Arduino Wifi Bee を使用して Cloudant に接続する方法

Question

Arduino ベースの wifi bee (ATmega 328P) を Cloudant データベースに接続しようとしています。wifi bee は wiwhield ライブラリを使用して Web に接続します。これを使用して、cosm (xively) に接続し、データを投稿/取得できます。しかし、cloudant ではそれができず、503 サービスを利用できないというリクエストを受け取り続けています。

問題は、Cloudant が DNS を使用するのに対し、Wishield は IP アドレスが指定されることを期待していることだと思います。wishield を使用してコード スニペットを追加しています。 .com、それは私に 503 リクエストを与えるだけです。

さまざまなコードを見つけてください: コード スニペット: GetDatafromCloudant.ino : Cloudant GET 要求の IP アドレス/ポートの詳細を変更しました。
