<![CDATA[Problems compiling example M5stack with arduino ide]]>Hello,
The M5STACK is new for me. After installing the software and start an example I get the next errors :

/Users/jankromhout/Documents/Arduino/libraries/M5Stack/src/LoRaWan.cpp: In member function 'void LoRaWanClass::init()':
/Users/jankromhout/Documents/Arduino/libraries/M5Stack/src/LoRaWan.cpp:45:5: error: 'Serial2' was not declared in this scope
Serial2.begin(9600, SERIAL_8N1, 16, 17);
^
In file included from /Users/jankromhout/Documents/Arduino/libraries/M5Stack/src/LoRaWan.cpp:33:0:
/Users/jankromhout/Documents/Arduino/libraries/M5Stack/src/LoRaWan.cpp: In member function 'void LoRaWanClass::getVersion(char*, short int, unsigned char)':
/Users/jankromhout/Documents/Arduino/libraries/M5Stack/src/LoRaWan.h:33:29: error: 'Serial2' was not declared in this scope
#define SerialLoRa Serial2
^

Wat do I missing?
Thanks for any help.
Cheers, Jan
