Hi mohit
you can refer the TcpClient example from SDK.

while one is good for send continews data on server using TCP application. RIL or URC?

Hi Mohit ,

If you are using TCP in OCPU then better to use the API instead of using AT command through RIL .

here is my code for… sim card status is every time give me an this error “SIM card status is unnormal!”

void proc_main_task(s32 taskId)
{
s32 WTDId;
s32 ret;
ST_MSG msg;
UART_Initialize();
WTDId=watchdog_cnf();
APP_DEBUG(“WTDId: %d\r\n”,WTDId);
APP_DEBUG(“OpenCPU: TCP program\r\n”);
while(TRUE)
{
Ql_memset(&msg, 0x0, sizeof(ST_MSG));
Ql_OS_GetMessage(&msg);
switch(msg.message)
{
case MSG_ID_RIL_READY:
{
APP_DEBUG("<-- RIL is ready -->\r\n");
Ql_RIL_Initialize();
GPS_OPEN(); // RIL_GPS_Open(1)
Switch_Sim(); // AT+QDSIM=1
UTCtime_syc();
SIMState(); // RIL_SIM_GetSimState(&simStat)
break;
}
default:
break;
}
}
}

where is the problem i did not found. MC60 every time give me a status of sim card is unnormal.

Hi Mohit ,

Are you finding this problem while switching sim or always ?

If it is after switching then you need to reset RF or Power to get SIM2 detected . you can send command AT+CFUN=0 and AT+CFUN=1 or you can reset the module after switching the sim .

If it is coming on both sims then you need to check your Hardware .

Thank you
Ratan

I try out Ql_restart(0) for restart module. is it worth it? also same problem after this command.
