Hallo miteinander,
schönes Projekt, allerdings habe ich über eine Stunde gebraucht, um auf TTN den Mapper anzulegen.
Er funktioniert im Prinzip nur meldet er nach einem ersten Übertragenen Koordinatensarz immer Beite=0, Länge=0 und Höhe =0.
Woran kann das liegen?
Das Kartenbild sieht wie folgt aus:
Der Code sieht so aus:
#include "SenseBoxMCU.h"
#include <SPI.h>
#include <lmic.h>
#include <hal/hal.h>
#include <CayenneLPP.h>
CayenneLPP lpp(51);

// This key should be in big endian format (or, since it is not really a

- no explanation for this.
