Ambient Library
Fork of AmbientLib by
Ambient library. It provides "set" function to set data to a packet and "send" function to send the packet to the Ambient server. It also provides "bulk_send" function to send multiple data. (Japanese: IoT用のクラウドサービス「Ambient」のデーター送信ライブラリーです。Ambientはマイコンから送られたセンサーデーターを受信し、蓄積し、可視化(グラフ化)します。http://ambidata.io)
