Issues with CC2650STK and local MQTT Broker. #196

Closed Mecabot closed 7 years ago

Mecabot commented 8 years ago

Hi guys:

I have tried to connect CC2650STK with local Mosquitto but i have not been succesful.

In the CC2650STK´s debug i received the following:

_Starting Contiki-3.x-2370-ge3d5b74 With DriverLib v0.44336 TI CC2650 SensorTag Net: sicslowpan MAC: CSMA RDC: nullrdc RF: Channel 25 CC26XX Web Demo Process CC26XX Web Server CC26XX CoAP Server 6LBR Client Process CC26XX MQTT Client Process CC26XX Net UART Process MQTT - Registered successfully Init Registered.

My Mosquitto´s configuration is:

bind_address 127.0.0.2 port 1885

I have monitored the port with the command sudo tcpdump -i eth0 -v -X port 1885 and I received the following:

Should I add some additional settings to mosquitto´s configuration?

If you are using 6LBR in Raw Ethernet mode you can not access servers on the same host, if your host is on another machine on the lan, you can not use 127.0.0.2 as it is a host only address

chenek commented 8 years ago

@Mecabot What HW do you run 6lbr? If it's BBB, Do you run wrapsix or6lbr NAT64 on BBB. You have to enable NAT64 to access MQTT server.

Mecabot commented 8 years ago

Hi, sorry for the late.

@laurentderu , i use other Raspberry Pi like a Mosquitto Broker, it is working but i don´t know why. My 6lbr.conf is the following:

_MODE=ROUTER RAW_ETH=0 BRIDGE=1 DEV_BRIDGE=br0 DEV_TAP=tap0 DEV_ETH=eth0 RAW_ETH_FCS=0 CREATE_BRIDGE=0 DEV_RADIO=/dev/ttyACM0 BAUDRATE=115200 LOGLEVEL=3

What should be my 6lbr.conf to have a Mosquittto Broker in the same Raspberry Pi? I only want to use a Raspberry pi.

@chenek my HW configuration is the following:

CC2650STK(CC26xx-web-demo) <-> CC2650STK(Slip-radio) <-> Raspberry Pi2 (Router with NAT64) <-> Raspberry Pi 2 (Mosquitto Broker) .

chenek commented 8 years ago

Try the following values to replace those in your 6lbr.conf

MODE=ROUTER RAW_ETH=1 BRIDGE=0 DEV_BRIDGE=br0 DEV_TAP=tap0 DEV_ETH=eth0 RAW_ETH_FCS=0

DEV_RADIO=/dev/ttyACM0 BAUDRATE=115200

LOG_LEVEL=3

Hi @chenek , i´ve tried your suggestion, but i´ve not been successful.

I got the following:

Do you have any other suggestion?

Currently i use an external Broker MQTT because my Raspberry Pi(configured like Mosquitto Broker and Router with NAT64 at the same time) cannot get the MQTT Messagges with the following configuration:

MODE=ROUTER RAW_ETH=0 BRIDGE=1 DEV_BRIDGE=br0 DEV_TAP=tap0 DEV_ETH=eth0 RAW_ETH_FCS=0 CREATE_BRIDGE=0 DEV_RADIO=/dev/ttyACM0 BAUDRATE=115200 LOG_LEVEL=3

And, when i use the next configuration i lose BR0 and TAP0:

MODE=ROUTER RAW_ETH=1 BRIDGE=0 DEV_BRIDGE=br0 DEV_TAP=tap0 DEV_ETH=eth0 RAW_ETH_FCS=0 DEV_RADIO=/dev/ttyACM0 BAUDRATE=115200 LOG_LEVEL=3

Any have a suggest for me?

Kind regards.

The second configuration configures 6LBR in Raw Ethernet mode, in this mode the BR access directly the Ethernet device and therefore does not create a tap interface and a bridge to connect it the the Ethernet interface. That explain why the host can not communicate with the BR.

Normally the first configuration should work, unless the bridge interface is not properly configured on the host. In that case the external hosts can access 6LBR through the bridge, but the BR host can not use the br0 interface.

Hey! I believe I'm facing a similar issue. I'm using CC2650 (slip radio) connected to a Linux Mint machine where 6lbr and mosquitto.rsmb are running. My 6lbr setup is the following:

_MODE=ROUTER RAW_ETH=0 BRIDGE=1 DEV_BRIDGE=br0 DEV_TAP=tap0 DEV_ETH=enp7s0 ETH_JOIN_BRIDGE=1 CREATE_BRIDGE=1 DEV_RADIO=/dev/ttyACM0 BAUDRATE=115200 LOGLEVEL=4

I'm using as node the CC2530. I'm able to send udp packages to my Linux machine(router), but it's not being possible to connect to the MQTT broker. Checking the network traces and even the console while MQTT is running, it's possible to see MQTT receiving a connection request from my node IP and sending the CONNACK, but my node doesn't catch it, it keeps trying to connect to the broker. In other words, the broker sees the connection as established but my node doesn't because the CONNACK did not arrive at it.

Analyzing a lit bit further, it seems that my node is not receiving packages at all, it can only send them. I did a simple python script (running on the router) that sends a udp package to the node. On my node firmware, I print on the terminal every package that I receive, but it's not printing anything when I run the python script (several times)..

@laurentderu, do you have any clues? It seems to me that the issue is before the MQTT connection, because it is not receiving any packages..

Thanks in advance!

I found out the problem. The IP that I was binding was not the same IP that my Linux was using to respond. I changed to the one that it was using and it worked. I know that it's not related to this issue anymore, but how can I communicate always with the same IP on the Linux? I need to connect to the broker every time my nodes start. For that, I would need a static IP that reaches this sensor network. How can I do that? I've tried creating a static IP with the prefix bbbb and even binding with the border IP (bbbb::100), but it didn't work..

laurentderu commented 7 years ago

It's a known problem on IPv6 network when privacy feature is enabled, the IP address of the host is periodically changed to avoid tracking, but if this host hosts servers, the client must be aware of the IP change.

The easiest workaround is to disable the privacy feature as it's not intended for server, you can disable it using the following sysctl parameter : net.ipv6.conf.eth0.use_tempaddr=0 (replace eth0 with your actual interface identifier).

Hi, We are also facing the same issue like not able to get connect to mosquitto broker running on the same BBB where 6LBR is also running.

As a first step we are planning to receive the data from Nodes to BBB using MQTT by setting up a mosquitto broker and later we are planning to take that to another IOT SDK running on same BBB to connect it to one of our IOT HUB.

So focusing on 1st step like connecting to local MQTT broker, please let me know which interfaces i need to configure and the configuration for 6LBR etc.

I tried with the following but not able to get the data in BBB MQTT Broker

6LBR Configuration is as follows, MODE=ROUTER

MODE=SMART-BRIDGE

MODE=RPL-RELAY

MODE=FULL-TRANSPARENT-BRIDGE

MODE=NDP-ROUTER

MODE=6LR

MODE=RPL-ROOT

RAW_ETH=1 BRIDGE=0 DEV_BRIDGE=br0 DEV_TAP=tap0 DEV_ETH=eth0

RAW_ETH_FCS=1

RAW_ETH_FCS=0 DEV_RADIO=/dev/ttyACM0 #2.4GHz USB Dongle will enumerate like ACM0

DEV_RADIO=/dev/ttyUSB1 #SmartRF06EB+CC13xxEM will enumerate like USB1

BAUDRATE=115200 LOG_LEVEL=3

also tried RAW_ETH=0 BRIDGE=1

In the interfaces we tried both, auto br0 iface br0 inet dhcp

auto eth0

iface eth0 inet dhcp

and,

auto br0

iface br0 inet dhcp

auto eth0 iface eth0 inet dhcp

@laurentderu Please let me know which configuration is correct and let me know your thoughts.

Thanks
