IPv4/IPv6 translation prefix expected in form ::ffff:1234:5678 instead of 0064:ff9b::1234:5678

IPv4/IPv6 translation prefix expected in form ::ffff:1234:5678 instead of 0064:ff9b::1234:5678


remove hardcoded broker_ip address (read from project-conf.h)

BUG=

[armangungor, 2017-10-15 20:53:40]

In last session we used IPv4 translated IPv6 address in 0064:ff9b::1234:5678
format because of the previous example. But actually ip64-addr module expects it
in ::ffff:1234:5678 form and it does not work with other formats.

For details check /contiki/core/net/ip/ip64-addr.c:
static uip_ip6addr_t ip64_prefix = {{ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0xff, 0xff,
0, 0, 0, 0}};

Please check my comments on the code regarding the "MQTT_DEMO_BROKER_IP_ADDR"
variable

iot_lab/avr-rss2/ipv6/iot_mqtt/mqtt-demo.c:71: static const char *broker_ip =
MQTT_DEMO_BROKER_IP_ADDR;
the same variable "MQTT_DEMO_BROKER_IP_ADDR" is defined two times.

iot_lab/avr-rss2/ipv6/iot_mqtt/mqtt-demo.c:75: static const char *broker_ip =
MQTT_DEMO_BROKER_IP_ADDR;
is the variable "MQTT_DEMO_BROKER_IP_ADDR" defined in the conf.h file?

[safa.ismail.SI, 2017-10-18 09:33:46]

kindly find my comments on the conf.h file.

It is clear that there is a change in the address format.
