nrf SDK IOT MQTT Publisher example, can't ping from bt0 and interface go down

Miafiaj

Hi,

I'm trying to do the iot mqtt publisher example with the nRF5_SDK_15.3.0_59ac345, a nrf52840 and a Raspberry Pi 3 B+ as a gateway but I got some problems :

After the connection with the nrf52840 (echo "connect 00:7E:3E:C4:C6:8C 1" > /sys/kernel/debug/bluetooth/6lowpan_control), LED1 stops blinking and bt0 show up but go down in approximatly 30s. And during the time when bt0 is up I can't ping anything with it.

I'm using a Raspberry Pi 3 B+ as the gateway and as MQTT Broker, with raspbian 9(2018-11-13-raspbian-stretch-full) using Linux 4.14.98-v7+, I tried the example with a nrf52840-DK and a nrf52832 but I get the same problems.

I followed all the instructions from the tutorials on internet (https://developer.nordicsemi.com/nRF5_IoT_SDK/doc/0.9.0/html/a00089.html for example) and I can't get to make it work.

I changed those parameters : 

#define APP_MQTT_BROKER_PORT                1883 

m_app_mqtt_client.transport_type = MQTT_TRANSPORT_NON_SECURE;

m_app_mqtt_client.p_security_settings = NULL; 

I put the localhost adress for the mqtt broker on localhost : 

I've also tried with putting just ::1 / eth0 ipv6 address or putting the MQTT Broker on my Windows 10 computer and its IPv6 on the address (I can ping6 my windows 10 computer from eth0).

Here my script used for the connection (00:07:3E:C4:C6:8C MAC address of my nrf52840) : 

#modprobe bluetooth_6lowpan
echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable
hciconfig
hciconfig hci0 reset
echo "Connecting.."
sleep 1
echo "connect 00:7E:3E:C4:C6:8C 1" > /sys/kernel/debug/bluetooth/6lowpan_control
echo 1 >  /proc/sys/net/ipv6/conf/all/forwarding
sleep 1
sleep 1
ifconfig bt0 add 2001:db8::1/64
service radvd restart

Here my radvd.conf :

interface bt0
{
        AdvSendAdvert on;
        prefix 2001:db8::/64
        {
                AdvOnLink off;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

Here the connection and test of bt0 :

I can ping 2001:db8::1 but this is all, I can't ping localhost / eth0 nor my card

Here is what I got from "tcpdump -i bt0 -vv ip6" during the time bt0 is up  and making a ping to the card:

Here what I get from /var/log/syslog after bt0 go down: 

I don't really know where the problems can come from, from what I've seen from the topic on forums, older os for the raspberry are recommended (like raspbian wheezy), since the project has a few years, but I can't put them on the raspberrypi 3b+.

So I've started asking myself if the problem doesn't come from the fact I use a raspberrypi 3b+ since i haven't see any post on the forums where someone use this model. Do you know if the problem can come from here ?

Thank you !
