Quecopen SMS read on EC200UCN

1

Hello everyone, I’m trying to read new SMS via Quecopen sms api. Unfortunately it does not work.

Used the sms_demo example.

uint16_t msg_len = 512;
ql_sms_mem_info_t sms_mem = {0};
ql_sms_recv_s *sms_recv = NULL;

char *msg = malloc(msg_len);
if(msg == NULL){
	QL_SMS_LOG("malloc ql_sms_msg_s fail");
	goto exit;
}
memset(msg ,0 ,msg_len);

ql_sms_get_storage(nSim, &sms_mem);
QL_SMS_LOG("mem1=%d, mem2=%d, mem3=%d", sms_mem.mem1, sms_mem.mem2, sms_mem.mem3);

//Read SMS messages as text
if(QL_SMS_SUCCESS == ql_sms_read_msg(nSim,2, msg, msg_len, TEXT)){
	QL_SMS_LOG("read msg OK text, msg=%s", msg);
}else{
	QL_SMS_LOG("read sms FAIL");
}

//Read SMS messages as pdu
memset(msg ,0 ,msg_len);
if(QL_SMS_SUCCESS == ql_sms_read_msg(nSim,2, msg, msg_len, PDU)){
	QL_SMS_LOG("read msg OK pdu, msg=%s", msg);
}else{
	QL_SMS_LOG("read sms FAIL");
}

SMS read faild.

ql_sms:user_sms_event_callback 68 read sms FAIL.

Please Help.

Hi @J_S_Sahoo,
May I ask how’d you compiled the firmware? What was the command you used?
SMS might require VoLTE to work so please try the “VOLTE” build option if you didn’t.

3

is there any command or instruction that allows a SMS to be sent successfully when the message contains special characters?
Thank you beforehand

In sms_demo.c

case QL_SMS_NEW_MSG_IND:
{
ql_sms_new_s *msg = (ql_sms_new_s *)ctx;
QL_SMS_LOG(“sim=%d, index=%d, storage memory=%d”, nSim, msg->index, msg->mem);
break;
}

Works, when new sms coming it shows.

case QL_SMS_LIST_IND:
{
#if 1
ql_sms_msg_s *msg = (ql_sms_msg_s *)ctx;
QL_SMS_LOG(“sim=%d,index=%d, msg = %s”,nSim, msg->index, msg->buf);
#endif

It also works at startup.

But if I want to read a sms using sms read api, does not work, showing read fail.

Hi @ShortyPTG
Could you give me an example of “special characters”?

Hi @J_S_Sahoo
The demo code by default reads the SMS message at index 2 (the third message) and will fail if the SIM card doesn’t have a message at that slot.
You can change the second parameter of the read API to 0 and see if you can read the first message.
And of course, make sure there is message to read in the first place.

Sim card has sms.

case QL_SMS_LIST_IND shows sms with index, msg, time .

ql_sms_read_msg(nSim,2, msg, msg_len, TEXT))
ql_sms_read_msg(nSim,2, msg, msg_len, PDU))

Both are not working, I also changed the index to 0 . But not working.

@J_S_Sahoo
Are you able to get the return value of ql_sms_read_msg()? Please share it here. Thank you.

ql_sms_read_msg

Return value -1

@J_S_Sahoo
Just want to make sure that you were using the untouched SMS demo at “components\ql-application\sms\sms_demo.c” right? A return value of -1 is kinda odd.
Also, you might want to try the ql_sms_read_msg_ex() API included in the demo and see if that works.

11

Ok I will try.

When new sms comming how to read that sms?

12

@J_S_Sahoo
A typical way of reading incoming SMS message is to release a message queue to another task that will do the actual reading in the SMS event callback. Reading SMS inside the event callback is not recommended.

Can you share the code ?

Here’s a SMS demo I modified:
sms_demo.pdf (9.7 KB)
Due to site limitation, I have to change the file extension before uploading. Please change the file extension back to ".c” after downloading or just open the file in a notepad or something. We apologize for the inconvenience.

Thank for sharing the code

EXAMPLES OF SPECIAL CHARACTERS: Ç, ~ å Ã
Kind regards

17

it works as i expected. Thank you

The characters å and à are not in the GSM 7-bit default alphabet or its extension table. But your first two characters are.

The characters å and à do appear in the GSM Portuguese National Language Single Shift Table (3GPP 23.038, section A.2.3).

Otherwise they can be encoded as Unicode in an 8-bit SMS.

19

All right, so, the message must use unicode 8 bit…

20

For those two characters, and in the absence of the Portuguese 7-bit extension table, yes.

These Unicode characters are 16 bits. You use 8-bit SMSs to transport them.
