組み込み系を初めた頃に作ったライブラリ。頻繁に仕様変更してきたのでコードにはまとまりがないがよく使う機能を集約したライブラリで基本機能としてＳＴＡ（マルチＡＰ）／ＡＰモード、ＮＴＰ、ＯＴＡ、ＷＥＢ、ＭＱＴＴに対応している。各設定値はフラッシュに保存するため基本機能に関するプログラミングは必要なくＷｉＦｉやＭＱＴＴの通信切断に伴う再接続処理も自動で行う便利なライブラリだ。再接続時にはＭＱＴＴのsubscribe()の再設定も行っている。
最初はフラッシュに保存するログ機能もあったのだが頻繁に書き込むと直ぐにフラッシュが壊れてしまうため削除してしまった。でも少量であったとしてもオンメモリでログする機能くらいは欲しいところ。今後の検討課題としておこう。
なお、ＭＱＴＴにはPubSubClientライブラリを利用しており、頻繁な切断を防ぐためタイムアウト値を規定の15秒からmosquittoサーバーを前提とした10秒に変更している。
設定画面については、画面設計が大の苦手な私ではこの程度が限界．．．誰かもっとかっこいいのを作ってくれないかなぁ。(笑)

【ライブラリ概要】
|
1 |
void begin(bool wifi_ap = false) |
ライブラリを初期化する。wifi_apをfalse指定(省略時)した場合、フラッシュに接続情報が保存されていればＳＴＡモード、保存されていなければＡＰモードでＷｉＦｉを開始し、true指定すると強制的にＡＰモードを開始する。ＡＰモードではＷｅｂ経由でＡＰ情報(SSID/PASSWORD)が登録可能。ＡＰ情報が登録されていて３分経過しても接続できない場合はＡＰモードに移行するが、モバイル対応のため一度でも接続に成功すると無限に接続を試行する仕様となっている。
ＡＰモードのアドレスとパスワードは、192.168.119.1
|
1 |
bool handle(); |
基本機能をハンドリングし戻り値にＷｉＦｉ接続状態を返す。但し、ＭＱＴＴサーバーを登録している場合はＭＱＴＴサーバーへの接続状態を返す。可能な限り頻繁に呼び出す必要がある。
|

bool publish(const char* topic, const uint8_t* payload = nullptr, size_t length = 0, uint8_t qos = 1, bool retain = false); |
ＭＱＴＴ送信を行う。詳細はMQTT/PubSubClientのドキュメントを参照。
|
1 |
bool subscribe(const char* topic, uint8_t qos = 1); |
ＭＱＴＴ受信トピックの登録。詳細はMQTT/PubSubClientのドキュメントを参照。
|
1 |

初期値設定用。タイムゾーンを設定する。
|
1 |
void getTimeZone(int *timezone,int *daylightOffset); |
タイムゾーンを取得する。begin()呼び出し以降に利用可能。
|
1 |
void setMQTTServer(const char* host); |
初期値設定用。ＭＱＴＴサーバーを登録する。
|
1 |
void setBuiltinLED(uint8_t pin); |
初期値設定用。ビルトインＬＥＤの出力ポートを指定する。
