ドローンの宅配サービスなどを自力で実現させたいと思い
P2Pによる無線ではなく、広域通信網に本体を接続して
自動操縦で目的を達成できるようになるためのやり方を
模索している中、下記のリンクの内容を学んだ
勉強会に2015年の11月ごろ参加しました。
Mac Book にてNode.js を使ってコードを編集し
パソコン1台でドローンを2台同時に操れることに驚きました。
勉強会での担当の方は
以下の記事を書いたのびすけさんでした。
下記はコードの一部です
var noble = require('./index');
console.log('noble');
noble.on('stateChange', function(state) {
console.log('on -> stateChange: ' + state);if (state === 'poweredOn') {
noble.startScanning();
} else {
noble.stopScanning();
}
});noble.on('scanStart', function() {
console.log('on -> scanStart');
});noble.on('scanStop', function() {
console.log('on -> scanStop');
});
noble.on('discover', function(peripheral) {
console.log('on -> discover: ' + peripheral);noble.stopScanning();

console.log('on -> connect');
this.updateRssi();
