kandi X-RAY | iot Summary
.NET can be used to build applications for IoT devices and scenarios. IoT applications typically interact with sensors, displays and input devices that require the use of GPIO pins, serial ports or similar hardware. IMPORTANT: This is the GitHub repo for the libraries. You might want to start with our official documentation. This repository contains the System.Device.Gpio library and implementations for various boards like Raspberry Pi and Hummingboard. The repository also contains Iot.Device.Bindings, a growing set of community-maintained device bindings for IoT components. NOTE: This repository is still in experimental stage and all APIs are subject to changes.

QUESTION
I have a system with IoT Hub to ingests events from devices and Device Provisioning Service to provision devices. IoT Hub C# SDKs are used for the management of device tags and desired properties (IoT Hub device twins), and to invoke direct methods or schedule jobs.
Recently I've been experimenting with Azure IoT Central. While I don't plan to use it, I've found Digital Twins (that are being used on Azure IoT Central) to offer a very good way of managing IoT devices and I would like to emulate the same kind of functionality and capabilities on my IoT system.
The high-level architecture of IoT Central does not seem to indicate the services or logic used to manage Digital Twins.
As far as I understand, there are two ways you can start using Digital Twins:
- Plug and Play Digital Twins
- Azure Digital Twins service
Question - is Azure IoT Central purely based on Plug and Play Digital Twins and/or does it also use Azure Digital Twins service?
...ANSWER
Answered 2022-Mar-02 at 08:02Yes, IOT Central is purely based on plug and play Digital Twins
plug and play Digital Twins enables solution builders to integrate IoT devices with their solutions without any manual configuration.
Azure Digital Twins can be used to design a digital twin architecture that represents actual IoT devices in a wider cloud solution, and which connects to IoT Hub device twins to send and receive live data.

QUESTION
I'm testing a deployment of the Eclipse IoT Cloud2Edge package and have followed the instructions here https://www.eclipse.org/packages/packages/cloud2edge/tour/ to test. After creating the new tenant and device, and configuring the connection between Hono and Ditto, I can send telemetry to the new device via the Hono http adapter as shown here:
...ANSWER
Answered 2022-Feb-14 at 07:56What you configured is the Connection source enforcement which makes sure that a Hono device (identified via the AMQP header device_id
) may only updates the twin with the same "thing id" in Ditto.
That enforcement fails as your thingId you set in the Ditto Protocol JSON is my-tenant:org.acme:my-device-1
- the topic
's first segment is the namespace, the second segment the name - combined those 2 segments become the "thing ID", see also: Protocol topic specification.
So you probably want to send the following message instead:

QUESTION
In an Android app which uses AWS services, if I deregister a registered ConnectivityManager.NetworkCallback
, the app can no longer contact AWS services. I am uncertain why this is occurring, or how to contact the AWS services again. Currently, the only way to reconnect to AWS is to terminate the app and restart it.
To elaborate, one function of the app is to connect the user's Android device to a different WiFi network hotspot for the purposes of setting up an IoT device. At this moment of use, the user would be logged in using AWS's Cognito service. Because how an app can connect to WiFi was changed starting with API level 29, this associated code is only invoked on such devices and the problem is isolated to said devices. Here is the relevant snippet for how the connection is being created:
...ANSWER
Answered 2021-Dec-07 at 17:48I realized the issue involved a snippet of code outside of the code shared in this question. The NetworkCallback's onAvailable()
is performed as such:

I would like to run a pod on one of my IoT devices.
Each one of those devices contains an environment variable I want this pod to use.
Is there any way to inject this env variable into the pod using build-in templating of helm

I was trying the following on my deployment.yaml

ANSWER
Answered 2021-Dec-06 at 01:10It's not possible to directly pass the host's env vars to the pods. I often do that by creating a ConfigMap.

QUESTION
I got this code to almost work, despite much ignorance. Please help on the home run!
- Problem 1: INPUT:
I have a long list of URLs (1000+) to read from and they are in a single column in .csv. I would prefer to read from that file than to paste them into code, like below.
- Problem 2: OUTPUT:
The source files actually have 3 drivers and 3 challenges each. In a separate python file, the below code finds, prints and saves all 3, but not when I'm using this dataframe below (see below - it only saves 2).
- Problem 3: OUTPUT:
I want the output (both files) to have URLs in column 0, and then drivers (or challenges) in the following columns. But what I've written here (probably the 'drop') makes them not only drop one row but also move across 2 columns.
At the end I'm showing both the inputs and the current & desired output. Sorry for the long question. I'll be very grateful for any help!
...ANSWER
Answered 2021-Nov-27 at 21:36Store your data in a list of dicts, create a data frame from it. Split the list of drivers
/ challenges
into single columns
and concat it to the final data frame.
QUESTION
My goal is to loop through all possible ipv4 address that could be used in the web (like a computer, IoT device, etc, just not private networks) combinations in Python. As I was searching, I found a couple of solutions:
1: Use a while loop and loop through the possible combinations (however, not sure this would stop, I ported this from a stackoverflow in C that I now cannot find):
...ANSWER
Answered 2021-Oct-26 at 06:50You can use ipaddress, it's in the standard library. is_private will exclude RFC1918 addresses (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) as well as some others.

ANSWER
Answered 2021-Sep-01 at 10:31You have a complex scenario here, composed of an end-to-end chain of 5 components:
- Prosys OPC-UA Server Simulation
- OPC-UA FIWARE IoT Agent
- Orion Context Broker
- FIWARE Cygnus Connector
- PostgreSQL database
My recomendation here would be to check every step in the chain (looking in logs, etc.) to ensure everything is correct before of checking the next step.

I'm tring to calculate time prorata between two dates over multi month periods using SQL on PostgresSQL.

If you force Postgres to ignore the timezone, it should work:
