ruby - Websockets と Adafruit Feather OpCode 11

Question

私の目標は、Adafruit Feather (WiFi) を自分のコンピューターで実行されている Websocket サーバーに接続することです。

サーバー: EventMachineシンプルサーバーの例
クライアント: ArduinoHttpClient > SimpleWebsocketExample

私の問題は、Feather をリセットすると再接続できない場合があることです。再接続する前に、数分、さらに数回リセットする必要があります。サーバーコードのデバッグフラグをオンにすると、次の 2 つのパターンが表示されます。

接続成功

while ループで Feather の再接続を試みます。私の問題は、非常に迅速な再接続試行からのデータのタイムアウト/スロットリングに関連するものかもしれないと思っていましたが、残念ながらそうではないようです。

問題を診断する方法についての考えは? 私はそのオペコードを潜在的な原因として注目していますが、サーバー側でそれを抑制しようとするか、クライアント側に配置されている理由を理解するかは不明です。
