我现在在用一个SIM300往服务器发送数据,具体指令如下:
AT
AT+CCID
AT+CGMR
AT+CSQ
AT+CGCLASS="B"
AT+CGDCONT=1,"IP","CMNET"
AT+CGATT=1
AT+CIPCSGP=1,"CMNET"
AT+CIPSTART="TCP","59.69.105.130","80"
CONNECT OK
AT+CIPSEND>
abc
SEND OK
但服务器上接收不到数据,还用另一个问题,在服务器上装一个TCP/UDP测试软件,端口号不管设成什么,AT+CIPSTART="TCP","59.69.101.130","80" CONNECT OK,但是假如把80改成和服务器上端口号一致就连接不成功,不知道是什么原因,忘高手指教,谢谢,急用 |
