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

+ * The bignum code uses double-width division to speed up some operations.
+ * Double-width division is often implemented in software that needs to

+ * and can be linked with an implementation of division for that type.
+ * By default division is assumed to be usable if the type is present.
+ * Uncomment this option to prevent the use of double-width division.
+ *
+ * Note that division for the native integer type is always required.
+ * Furthermore, a 64-bit type is always required even on a 32-bit
+ * platform, but it need not support multiplication or division. In some
+ * cases it is also desirable to disable some double-width operations. For
+ * example, if double-width division is implemented in software, disabling

+ * MBEDTLS_ECP__FUNCTION_NAME__ALT: Uncomment a macro to let mbed TLS use your

+ *
+ * This partially replaces one function. The header file from mbed TLS is still
+ * used, in contrast to the MBEDTLS_ECP_ALT flag. The original implementation
+ * is still present and it is used for group structures not supported by the
+ * alternative.
+ *
+ * Any of these options become available by defining MBEDTLS_ECP_INTERNAL_ALT
+ * and implementing the following functions:
+ *      unsigned char mbedtls_internal_ecp_grp_capable(

+ *      void mbedtls_internal_ecp_deinit( const mbedtls_ecp_group *grp )
+ * The mbedtls_internal_ecp_grp_capable function should return 1 if the
+ * replacement functions implement arithmetic for the given group and 0
+ * otherwise.
+ * The functions mbedtls_internal_ecp_init and mbedtls_internal_ecp_deinit are

+ *
+ * Example: In case you uncomment MBEDTLS_ECP_INTERNAL_ALT and
+ * MBEDTLS_ECP_DOUBLE_JAC_ALT, mbed TLS will still provide the ecp_double_jac
+ * function, but will use your mbedtls_internal_ecp_double_jac if the group is
+ * supported (your mbedtls_internal_ecp_grp_capable function returns 1 when
+ * receives it as an argument). If the group is not supported then the original
+ * implementation is used. The other functions and the definition of
+ * mbedtls_ecp_group and mbedtls_ecp_point will not change, so your
