How to see Azure IoT SDK C logs using TI CC3235SF MCU on a serial monitor?

Question

Hello!

I am using the TI CC3235SF MCU (custom board) and the Azure IoT SDK C (C language) to connect my gateway to Azure IoTHub.

I have set the "logtrace" option to true to get the logs using LL SetOption function.

I print out my debug logs onto a serial monitor via UART using the following print function -

   

void debug(const char *format, ...)

{

    char date[20];

    va_list args;

    va_start(args, format);

    while (pthread_mutex_trylock(&printfMutex))

    {

        usleep(5000);

    }

    struct timespec tspec;

    clock_gettime(CLOCK_REALTIME, &tspec);

    unsigned int hrs = tspec.tv_sec / (60*60);

    unsigned int min = (tspec.tv_sec - hrs6060) / 60;

    unsigned int sec = (tspec.tv_sec - hrs6060 - min*60);

    sprintf(date, "[%02d:%02d:%02d.%03d] ", hrs % 24, min, sec, tspec.tv_nsec / 1000000);

    fprintf(stderr, "%s", date);

    vfprintf(stderr, format, args);

    va_end(args);

    pthread_mutex_unlock(&printfMutex);

}

   

I want to see extensive Azure IoT SDK logs such as shown below-

How to enable such detailed logs? Do I need to do anything else other than setting the "logtrace" option to true?

-> 14:36:13 CONNECT | VER: 4 | KEEPALIVE: 240 | FLAGS: 192 | USERNAME: [...] | PWD: XXXX | CLEAN: 0
<- 14:36:13 CONNACK | SESSION_PRESENT: false | RETURN_CODE: 0x3

Hello @Y MRUDULA,

welcome to this moderated Azure community forum.

This SDK is hosted on GitHub as an open source project.

If you want to ask detailed questions, the creators/moderators of that repository are in a better position to answer them.

Just create an issue over there and cross reference that one here.
