Christian Dupaty / Mbed OS LORAWAN-TTN-CAYENNE-LM35

Demo program for LoRaWan with data formated for cayenne interface on mydevices.com Check on https://goo.gl/fTUDNc

Dependencies:   Cayenne-LPP

Demonstration d'un node LoRaWan sur carte : Discovery IOT STmicro : B-L072Z-LRWAN1 https://www.st.com/en/evaluation-tools/b-l072z-lrwan1.html

L e code original MBED-ARM : https://os.mbed.com/teams/mbed-os-examples/code/mbed-os-example-lorawan/ est une application de l'API LoRAWan https://os.mbed.com/docs/v5.9/reference/lorawan.html

Le code original a été adapté pour une carte B-L072Z-LRWAN1 équipée d'un capteur de température LM35 connecté en 3.3v sur le port PA_0 (port analogique AN0) Les données sont formatées "cayenne" et visualisables sur mydevices.com ( https://goo.gl/fTUDNc ) Documentation cayenne : https://mydevices.com/cayenne/docs/lora/#lora-cayenne-low-power-payload

Les essais ont été réalisés avec une passerelle TTN https://www.thethingsnetwork.org/ le "Payload Format" ayant été configuré pour "Cayenne LPP"

Des capteurs virtuels on été également ajoutés (humidité, température, lumière, etc...) pour les essais au format cayenne.

Données physiques transmises (downlink)

- Température sur capteur LM35 - Tension sur PA_1 (AN1) est transmise entre 0% et 100% - Etat du bouton bleu

Données physiques reçues (uplink) Un actionneur permet d'allumer/eteindre à distance la led verte de la carte B-L072Z-LRWAN1

L'interface mydevice.com proposé permet de visualiser :

- Les capteurs virtuels - La température réelle sur LM35 - L'état du bouton bleu
