Hi.

error number tested = -1.

Do you have any example how to get IMEI .

Thanks

A good way to find out a little bit more about why the socket function returns false, is to print errno. Would you mind doing that?

Otherwise, there are two alternatives to get the IMEI:

AT command interface library using the function at_cmd_write instead of socket. https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.5.0/nrf/include/modem/at_cmd.html#
Modem interface library using the function modem_info_short_get instead of socket, for instance. https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.5.0/nrf/include/modem/modem_info.html

Cheers!

Markus

Hi.

in Main I issue the command GetIMEI();

Attached some code devzone.nordicsemi.com/.../at.c

The line at_sock = socket(AF_LTE, 0, NPROTO_AT); in at.c return false.

Is there another way to get the IMEI number within the code ?.

Bye.

Thanks for the code snippet, Ephraim!

However, I can’t find any information about the function “at_exec_reply”. What does it do?

Regards,

Markus

Hi.

This is the code

void GetIMEI(void)
{
int reply_buf_len;

reply_buf_len = at_exec_reply("AT+CGSN=1", 9, &reply_buf[0], 30);//NTP_GET_CURR_UNIX_TIME_MAX_REPLY_LEN)

memcpy(&imei_buf[0] , &reply_buf[8] ,15);
// imei_buf[15] = NULL;
imei_buf[15] = 0x2f;
imei_buf[16] = 0x53;
imei_buf[17] = 0x54;
imei_buf[18] = NULL;
}

It worked before .

Now I get the error [at_exec_reply:59] ERROR: AT commands socket error.

Please Advise

Hello Ephraim,

I assume that you are using Zephyr 2.4.99.

Function “at_exec_reply”, is that something you wrote yourself?

Can you elaborate “no longer works”? Does the application still compile?

Markus
