MQTT client - calling nrf_getaddrinfo couse reset

[Uri Rotshtein]

I'm using the nrf9160dk (ns). I started an application based on the SIMPLE_MQTT sample. At first, every this worked. I added my one MQTT client with a different set of buffers and structures.

The "original" MQTT client (the one that runs from main.c) is working well. When I try to create 2nd client from a different thread, (and the LTE is connected), once I get to nrf_getaddrinfo the system reboot itself.

Following is the code that eventually calls to nrf_getaddrinfo. (the same nrf_getaddrinfo  worked fine when called from main)

static int rit_broker_init(uint8_t *host, unsigned short port)

{

    int err;

    struct addrinfo *result;

    struct addrinfo *addr;

    struct addrinfo hints = {

        .ai_family = AF_INET,

        .ai_socktype = SOCK_STREAM

    };

    err = getaddrinfo(CONFIG_MQTT_BROKER_HOSTNAME, NULL, &hints, &result);

    if (err) {

        LOG_ERR("getaddrinfo failed: %d", err);

        return -ECHILD;

    }

.....

Hi,

That code by itself should not trigger an hardfault.

Could you share the log from the application?

There might be some more information in the crash log that could be helpful.

Best regards,

Didrik
