-### Temporary Manual Fix
-This issue has been fixed but not released yet, until then you will need to insert three lines of code in a library file.
-Insert the following:
-```
-#ifndef NULL
-#define NULL  0
-#endif
-```
-Into the file found here:
-linux: /home/{user}/Arduino/libraries/IBM_LMIC_framework/src/lmic
