Hello,
I need a little help regarding IoT-SDK 0.8.0 on nRF51.
What I want to achive: Get the IoT-SDK 0.8.0 MQTT-Example running on nRF51 and publishing sensor data to a Raspberry Pi 3 using IPv6 and MQTT. Later, more sensor nodes should publish their data "simultaneously".
What my current situation is: I flashed the IoT-Softdevice along with the recompiled example code into the nRF51. On the Pi, I started with a freshly installed Debian Jessie lite. First, I installed the mosquitto broker and radvd (there was no bt0-device present at this point):
sudo su
apt-get install mosquitto
apt-get install radvd
After that, I created the config file for radvd:
nano /etc/radvd.conf
with the following content:
interface bt0
{
AdvSendAdvert on;
prefix 2001:db8::/64
{
AdvOnLink off;
AdvAutonomous on;
AdvRouterAddr on;
};
};
First question here: How do I know "my" prefix? Or is it always the same as in the example? Then I started radvd:
echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
service radvd restart
After that, I found the nRF51-device using "hcitool lescan":
00:AB:C8:3A:XX:YY MQTTPublisher
Then I started the 6lowpan stack:
modprobe bluetooth_6lowpan
echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable
But there was still no bt0-device visible in the output of "ifconfig".
After that, I tried to establish the connection with
echo "connect 00:AB:C8:3A:XX:YY 2" > /sys/kernel/debug/bluetooth/6lowpan_control
but the board is not leaving the advertising mode nor is bt0 visible on the Pi.
Thats the point I am stuck at the moment. Can you tell me what I miss?
Thank you very much in advance!
Best Regards
