b4r_main.cpp:9: error: '::Serial1' has not been declared
::Serial1.begin(9600);
^
b4r_main.cpp:10: error: '::Serial1' has not been declared
b4r_main::_serialnative1->wrappedStream = &::Serial1;

exit status 1

Thanks

Try it with this code:

#if C
HardwareSerial Serial1(2);
void SerialNative1(B4R::Object* unused) {
 Serial1.begin(9600); //<--You can change the baud rate
 b4r_main::_serialnative1->wrappedStream = &Serial1;
}
#end if

RX pin is 16, TX is 17
