nRF9160 MQTT IPv6

[Balamurugan]

Hi,

nRF9160 mqtt works with ipv4 by using "ncs\nrf\samples\nrf9160\mqtt_simple" application.

Now NB-IOT network which we are using is faced out the IPv4 and moved to IPv6. Now  nRF9160 is not connecting to mqtt server.

By looking into "ncs\nrf\samples\nrf9160\mqtt_simple" (https://github.com/NordicPlayground/fw-nrfconnect-nrf/blob/master/samples/nrf9160/mqtt_simple/src/main.c) it supports only IPv4.

Could you please point to IPV6 mqtt samples or any other client samples like COAP etc,.. that support IPv6.

Hi.

If you look at the example ncs\nrf\samples\nrf9160\aws_fota\src\main.c, you can see that both IPv4 and IPv6 is supported.

(Line 243 - 255)

        } else if (addr->ai_addrlen == sizeof(struct sockaddr_in6)) {

            /* IPv6 Address. */

            struct sockaddr_in6 *broker =

                ((struct sockaddr_in6 *)&broker_storage);

            memcpy(broker->sin6_addr.s6_addr,

                ((struct sockaddr_in6 *)addr->ai_addr)

                ->sin6_addr.s6_addr,

                sizeof(struct in6_addr));

            broker->sin6_family = AF_INET6;

            broker->sin6_port = htons(CONFIG_MQTT_BROKER_PORT);

            printk("IPv6 Address");

            break;

I think you should be able to just add this code to the broker_init() function.

Best regards,

Andreas

Thanks for quick reply.

I will add IPv6 code and give a try.
