Main .ino file:

#include "bluevmega.cpp"

void setup()
{
 
 Serial.begin(57600);
 delay(1000);
}

void loop()
{   
	hwsetup(); [b]// GLOW: added beacuse I've renamed init() into hwsetup() !!!!!!!!!!!![/b]

	int ret;
    unsigned char lastdisp[12];
	Serial.println("V1MegaTool");
    for (;;) {
		for (;;) {
		ret = readpkt(respget); [b]// FX: STAY BLOCKED HERE !!! (GLOW)[/b]
			if (ret < 5)
                continue;
            if (respget[3] == INFDISPLAYDATA)
                break;
        }
        if(legacy > 32)
            printser(pullp(PSTR("LEGACY! only V works\r\n")));  
			inbuf[inhead++] = Serial.read();
            printser(pullp(PSTR("Mute (ESP)Hold systemUp mainDisp Euro Custom\r\n")));
            lastdisp[0] = 0;
            while (1) {
				ret = readpkt(respget);
                if (ret < 5) {
                    continue;
					}
                if (respget[3] == INFDISPLAYDATA && memcmp(lastdisp, respget, 12)) {
					showinfdisp();
                    memcpy(lastdisp, respget, 12);
                }
				if (Serial.available() >= 1 ) {
				inbuf[inhead++] = Serial.read();
				}
		    }
            break;
        }
