Bonsoir a tous,
je suis un newbie dans le LoRa et arduino,
Je voudrais quelque conseils sur mon projet
je voudrais developper quelques capteur d'ouverture et fermeture en lora et fonctionnant sur le reseau live objects d'orange pour de la notification en domotique.
J'ai trouver sur le net des tutos a base de librairie arduino-LMIC ca fonctionne bien, mais je ne sais comment le modifier pour faire du TX manuellement par bouton ou contact.
ame charitable merci d'avance
