I have got my Pi working with this recipe, but how do I stop it from sending the sensor information (d.myName, d.cputemp, etc.) every second? I had another Pi added awhile back and it is still in the device list but it isnt sending this information every second, but I dont remember what I did to it to get it to stop sending this information.

just few mouse clicks. There is no coding involved.

We have tried it from our end, it usually takes a minute or 2 to notice the network is not connected. It depends on the network stack of your linux. When MQTTClient gets the message that the network is not connected, MQTTAsync_isConnected will return false and the reconnect logic will kick in. This code will take care of reconnect logic as well. So as soon as the client becomes disconnected, it will try to reconnect.

The installer is available at the source code is available at In case you want to change the default behavior, you can modify the code and build it.

In this blog, the contents of the device.cfg are listed in a single line. Seems the sudo service iot start does not like it, and keeps failing when I restarted it.

More precisely, the reboot is implemented in line 126

Hi, I tried to download the installer from Github but my raspberry pi shows Warning: Failed to create the file iot_1.0-2_armhf.deb: Permission denied

The iot process starts and publishes events to theIBM Watson IoT Platform Quickstart. The process runs as a system service, and starts whenever Raspberry Pi starts. To verify the process is running, use the command:

Say if I want the raspberry pi to do something other than reboot.

Package libssl1.0.0:armhf is not configured yet.

If you want to understand to how to send a command to the raspberry pi, you can refer this recipe which sends a command using Node-RED.

So, I broke it up into multiple lines and started the iot process, and now the iot process is running.

In this step, we saw how to send a command to the device to control it using a Node-RED application.

Im using the Raspberry Pi 2, wheezy v 4.1.13. What version are you running and are you using ether or a Wifi Dongle? Also is there any documentation on what is actually performed when calling MQTTAsync_isConnected? And by reconnect logic does this mean youre making calls to the network stack to try and restart a particular network interface or is it just the reconnect logic that I see in the sample C code.

I have a raspberry Pi that is generating data in json format. I have created the iot device in Watson IoT Platform but still showing the device disconnected. No data from msg.payload in node-red application.

When I disconnect ether/wifi it takes up to +15min for this example to notice its not connected anymore. any ideas why?

Watson IoT Platform Registered connection

I think, the following needs to be done in Python to connect to a device registered on Watson IoT platform. However, the connection never goes through; keeps failing as Connection reset by peer. So, what do I need to do to make the connection happen from a Pi to the WIoTP?

Is this iot service a essential component, or just an example program? Im a bit confused because I cannot get the device ID without installing it in my Raspberry Pi. However, after the registration, it just keep sending test events and I have no way to change its behavior.

Where or how do I send the commands ?

which means I have to regenerate it again and save it somewhere. I wished the Authentication Token was also visible when I clicked on the API Keys, in the dashboard.

Hello, where exactly is the code for logging and command?

I think you might be referring to a Bluemix related question? If you visit the IoT forum and post a question someone from the team will help you

But this issue occurs because the library still does not get the correct code from the interface that the connection has been lost.

When the Raspberry Pi Sample is running in registered mode, it supports the receipt of Commands sent by an Application.

This sample uses the open source Paho client libraries to make the MQTT calls. So the documentation for the isConnected can be found in The reconnect logic is in the sample code. The logic is present just in the code, and it does not make calls to the network interface.

mqttc = mqtt.Client(client_id=d:orgId:deviceType:deviceName)

You can stop the iot process with the following command:

The iot service is not an essential component and is just an example program. The device Id could be any id as long as its unique in a given Bluemix organization. What the iot service does is provides the MAC Address of the Raspberry Pi.
