About Google Cloud IOT core connect to device - google-cloud-iot

I m beginner use google cloud platform. I current do my Final Year Project . I want ask about google cloud iot core. How device like temperature sensor connect to device registry?
Regards,
Thank you

First you'll need to create a Google Cloud Platform project. Go to http://cloud.google.com and click the Getting Started button and it will walk you through getting your first project up and running.
Next, you'll want to go here and follow the Quickstart Guide and it will walk you through creating a virtual device (code only, no physical device) using Node.js. If you prefer to use Python, I have a very detailed walkthrough for using Raspberry Pi here.
In terms of getting the hardware part working, the easiest (in my opinion) is going to be Raspberry Pi and Node.js, and use the johnny-five module.

Offline mirror for Firebase

We have a client interested in our app, which relies on Firebase. However, they want to use this while they are out to sea and won't be able to connect to the cloud.
They do have a local server and a local wi-fi network.
Does anyone know if using the Firebase Local Emulator Suite would be a practical solution to this problem?
The Firebase Emulator Suite is for development, not sure production use. From its documentation:
The Firebase Local Emulator Suite is a set of advanced tools for developers looking to build and test apps locally
So it is (currently at least) not suitable for using in the scenario you describe.
What you can do is look at the offline mode of the various Firebase products, to see if they fit your needs. I recommend checking the documentation for each, or this handy video that covers all of them: Firebase offline: What works, what doesn't, and what you need to know.

Login Form With Fingerprint Sensor Using VB6 And Arduino UNO

How can I interface my Fingerprint Sensor using VB6? I've already made a login form but I need help using the fingerprint sensor for the security. Please help me, thanks in advance.
Here's a good starting point: Getting Started with Optical Fingerprint Reader – R305. It's for the 305 but the overall setup should be very similar if not identical. Most importantly you will find an SDK for R30X modules in the Resources section of this page. It includes drivers, demos (with source code), SYNO API, user manual, etc.
Also, Vishnu M Aiea wrote a C++ library to handle communication with the R307 sensor: R30X Arduino Library. You should consider using this to handle the communication aspect since it's already been built for you. You might need to get it compiled into a DLL to use with VB6.
There's also an article he wrote about the whole setup process: Interfacing R307 Optical Fingerprint Scanner with Arduino
These links thoroughly explain how to set everything up. I think with all this information you should be able to make a lot of progress and come back to Stack Overflow with more specific questions.

Custom Wake Word with Speech SDK

I'm looking for a way to have an application just process voice commands every time I say a specific phrase. The behavior should be similar to Cortana, Alexa or others. The application will be deployed on a hands-free device, but the Speech device SDK cannot be used, because it runs solely on a PC.
Is there an addition to the Speech SDK with a custom wake word yet?
MS speech recognition uses RESTful APIs to cloud services. You can use them from any device.
You can use speech-to-text and voice command services on Android or iOS. https://azure.microsoft.com/en-us/services/cognitive-services/speech/?v=18.05: Examples exist for both Java and Objective-C.
I think you also want to check out the preview of speaker recognition.
https://learn.microsoft.com/en-us/azure/cognitive-services/speaker-recognition/home
Does this help?
Looks like you would need to go to a specific site to set a wake work as it's still in preview mode. That will generate some files that you'd download for the SDK.
There's more in this documentation page.

Android Things - OTA via bluetooth?

I haven't had much success searching for this. I'm developing an Android Things application that will connect to a user phone to do certain things. I want to use this for delivering app updates as well.
So far, my crude searches on this have just discussed OTA via the Console and thus internet.
My gut has said that I could just build this - I could have a new version of the APK, transfer it to my device via bluetooth, and then just have the device copy it over the old one and reboot. But, not sure. I was hoping maybe there was an API for this and I'm just not wise enough to know how to find it via the searches.

How to edit or modify Kaa sandbox demo app

I am thinking of doing further work on kaa projects but i have few questions. I actually want to modify the source code of the GPIO control esp and GPIO control android. Is this posible? I mean downloading the demo source code fromm Kaa sandbox and editing them.
What IDE do i use for the GPIO control esp and GPIO control android? How do i compile them. How do i run them again on my android phone and on ESP8266 device?
I will appreciate a guide to doing this or a better way of doing this.
Thank You,
You can download code of Kaa Sample Applications from Kaa Sandbox (or GitHub), but changing the code embedded on Kaa Sandbox is not trivial and long procedure.
Should you want to contribute your code changes, you may open a pull request on GitHub's Kaa Sample Applications repository.
Regarding your question about IDE. Kaa project does not limit or recommend using (or not using) of any IDE. That means you can use any one suitable for you. Also, you would normally use different IDE of Android and ESP8266. You should check the appropriate platforms recommendations and documentation on how to develop, debug and program the respective devices.
