J'ai un projet où le serveur node.js parle avec l'arduino vrai d'une socket TCP. Il reçoit toutes ses données d'une page Web true a socket.io et les transfère ensuite sur le socket TCP. Tout fonctionne bien. Sauf quand:Node.js avec socket TCP à arduino
Je télécharge mon arduino avec un nouveau logiciel, Ou quand je débranche mon câble Ethernet, Lorsque j'ouvre mon moniteur série deux fois sur l'Arduino. J'ai eu events.js: 85 throw er; // Unhandled 'erreur' événement Erreur: lire ECONNRESET à exports._errnoException (util.js: 746: 11) à TCP.onread (net.js: 550: 26)
Est-ce que tout savoir quel est le problème . Comment puis-je le réparer en particulier une fonction de connexion automatique.
