Hallo,
I tried to connect an BMP0180 to a CubeCell and send the data over LoraWan.
The example LoRaWAN worked fine.
The example BMP0180 on GitHub could be compiled.
So i put it together:
#include "LoRaWan_APP.h"
#include "Arduino.h"
#include <Wire.h>
#include "BMP180.h"
BMP085 bmp;
// TTN-Parameter für ABP und OTAA in comissioning.h in der Library LoRaWan_APP
#ifndef ACTIVE_REGION
#define ACTIVE_REGION LORAMAC_REGION_CN470
#endif
#ifndef CLASS_MODE
#define CLASS_MODE CLASS_A
#endif
DeviceClass_t CLASS=CLASS_MODE;
/*
** * set LoraWan_RGB to 1,the RGB active in loraWan**
** * RGB red means sending;**
** * RGB purple means joined done;**
** * RGB blue means RxWindow1;**
** * RGB yellow means RxWindow2;**
** * RGB green means received done;**
** /*
#ifndef LoraWan_RGB
#define LoraWan_RGB 0
#endif
/ set to 1 the enable AT mode/ set to 0 the disable support AT mode /
#define AT_SUPPORT 1
/*!
** * When set to true the application uses the Over-the-Air activation procedure**
** * When set to false the application uses the Personalization activation procedure**
** /*
bool OVER_THE_AIR_ACTIVATION = true;
/ LoRaWAN Adaptive Data Rate /
bool LORAWAN_ADR_ON = true;
/ Indicates if the node is sending confirmed or unconfirmed messages /
bool IsTxConfirmed = true;
/*!

*** 6 | max(DR-2,0)**
*** 7 | max(DR-3,0)**
*** 8 | max(DR-3,0)**
*** Note, that if NbTrials is set to 1 or 2, the MAC will not decrease**
*** the datarate, in case the LoRaMAC layer did not receive an acknowledgment**

But now i got this Errors:

What is the Problem?
