MC60 QENG data in openCPU and multi line data

IoT Modules GSM Module

Hi support, I wanted to know how to get access the data acquired through QENG in open cpu applications. I also wanted to know how to read multi-line responses generated, I am attempting to read ussd code responses, but am only able to read the first line.

Thank you.

Hi Rohit
You can use Ql_RIL_SendATCmd to send any AT commands to module in openCpu code. So using Ql_RIL_SendATCmd you can send QENG related AT commands and handle the response in code.
For reading multiple line in response handler you can use Ql_strcat to con-cat multiple lines response.

Hi Rohit,

please find the below function to read multiple line response.

Step1 :

you can declare one array

static char strUrcResBuff[1024];

​

Step 2:

please write At response handler function as below

//---------------------------------------------------------------------------------//

static s32 ATResponse_Handler(char line, u32 len, void userData)
{
char* pHead = NULL;

pHead = Ql_RIL_FindString(line, len,userData);
if(pHead)
Ql_memset(strUrcResBuff, 0x0, sizeof(strUrcResBuff));

Ql_strcat((strUrcResBuff),line);

if (Ql_RIL_FindLine(line, len, “OK”))
{
return RIL_ATRSP_SUCCESS;
}
else if (Ql_RIL_FindLine(line, len, “ERROR”))
{
return RIL_ATRSP_FAILED;
}
else if (Ql_RIL_FindString(line, len, “+CME ERROR”))
{
return RIL_ATRSP_FAILED;
}
else if (Ql_RIL_FindString(line, len, “+CMS ERROR:”))
{
return RIL_ATRSP_FAILED;
}
return RIL_ATRSP_CONTINUE; //continue wait
}
//---------------------------------------------------------------------------------//

so response from AT command will stored in strUrcResBuff array.

Step 3: You can send AT commands using Ql_RIL_SendATCmd function.

for using above response handler you have send command like below

ret = Ql_RIL_SendATCmd(“AT+CUSD=1,”*123#"\r\n",Ql_strlen(“​AT+CUSD=1,”*123#"\r\n"), ATResponse_Handler, " +CUSD: ", 0);

where +CUSD: is first line desire response. so if desire response received strUrcResBuff will clear all old data and store new response

similar for AT+QENG?

ret = Ql_RIL_SendATCmd(“AT+QENG?\r\n”, Ql_strlen(“AT+QENG?\r\n”), ATResponse_Handler, " +QENG: 1,0 ", 0);

please find the below snaps.
