8051程式，只提供藍牙方式，一樣自己google，google絕對比我說老半天還仔細
ORG 00H
JMP START
START:
MOV TMOD,#00100000B
ANL PCON,#01111111B
MOV TH1,#244 ;鮑率最低2.4K，這要跟8051外接的藍牙一樣
MOV TL1,#244
SETB TR1
MOV SCON,#01010000B
;自己放延遲0.xxx秒
START0:
JNB RI,START0
MOV A,SBUF
CLR RI
CJNE A,#1,START0 ;1是手機傳給8051一個開始接收訊號,要搭配手機程式的z
START1:
;自己放延遲0.xxx秒
MOV P1,#0FFH
MOV A,P1
MOV SBUF,A ;傳給藍牙
JNB TI,$
CLR TI
JMP START1 ;跳回START1繼續讀取資料再傳藍牙
