sim900a模块问题

fire_Man

我在源代码上修改，自己进行gprs网络连接：问题如下：

[mw_shl_code=c,true]void sim900a_gprs_test(void) { u8 *p,*p1; p=mymalloc(100); if(sim900a_send_cmd("ATE","OK",1000)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"??±?????:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CIPCLOSE=1","CLOSE OK",100)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"??±?????:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CIPSHUT","SHUT OK",100)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"??±????????°:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CPIN?","OK",1000)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"?é???¨×???:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CREG?","+CGREG:",1000)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"?é??GSM×???:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT++CGREG?","+CGREG:",1000)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"?é???¨GPRS×???:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CIPMUX=1","OK",1000)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"?????à?·????:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CGATT=1","OK",1000)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"??×?GPRS????:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CSTT=\"CMNET\"","OK",1000)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"?è??GPRS??????:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CIICR","OK",1500)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"?¤?????????°:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } if(sim900a_send_cmd("AT+CIFSR","OK",1000)==0) { p1=(u8*)strstr((const char*)(UART2_Rev_Buf+2),"\r\n"); p1[0]=0;//?????á??·? sprintf((char*)p,"????±???IP:%s",UART2_Rev_Buf+2); GET_ARRAY_LEN(UART2_Rev_Buf,UART2_length); UART1_SendStr(p,UART2_length); UART2_length=0; USART2_RX_STA=0; } myfree(p); //while(1) //{ //sim900a_tcpudp_test(); // delay_ms(10); //} } [/mw_shl_code]

收到的数据总是有问题吗，请问代码哪里出问题了，看不明白啊

正点原子

直接用我们例程测试，可以通信么？
