밑에 질문 했던 것처럼 블루투스 포트를 E 포트로 변경도 해보고,
블루투스 포트를 D 포트로 사용하면, LCD에서 사용하는 포트를 C로 전부 옮겨봤는데도 실패하였습니다...
그래서 블루투스 포트를 E 포트(PE0, PE1) (RXD0, TXD0)으로 하려고 하는데도 동작이 되질 않습니다...
블루투스를 E포트로 사용하려면 코드를 수정해야 하는지 도와주시면 감사하겠습니다..

void init_uart1(){
UCSR1B=0x18; UBRR1L=8;
}
UART0을 사용하려면 UART1을 설정하지말고 UART0을 설정해야겠죠?
void init_uart0(){
UCSR0B=0x18; UBRR0L=8;
}
나머지 함수들도 UART0으로 변경합니다.
//
char available0(){ if(UCSR0A&0x80)return(1); else return(0); }
char getchar0(){ while(!(UCSR1A&0x80)); return(UDR0); }
void putchar0(char c){ while(!(UCSR0A&0x20)); UDR0=c; }
void puts0(char *s){ while(*s)putchar0(*s++); }
