So, I have created a normal Bluetooth app and I did faced many troubles for trying to connect to a device (Only Bluetooth headphone)from the app programmatically. That's why I thought that I would lead the user to the Bluetooth setting page using intent and it all works till now. Now I am trying to know if it is possible for me to redirect the user to app after he connects with a Bluetooth device from the Bluetooth setting page ?
The code is in JAVA
Anyone please help me with the connection problem I am facing. The app only connects to Bluetooth headphone and nothing else. If anyone has a working code for the connection in Bluetooth it would be a great favor
I am trying to test a website on mobile devices, but I keep getting timeouts on Android (using Chrome) and iOS tablets and smartphones (using Safari). My Windows tablet and a separate Windows PC (both using Chrome) work fine. Here is my network setup. It's a little convoluted, but blame COVID-19 and working remotely for that.
Web Application: DotNetNuke running on IIS using dedicated MSSQL database to store user account information and localization settings.
Web Server: Windows 10 running a local MSSQL web server database and IIS. Connected Wireless to my internal network. Using a VPN client to connect to the Rest API within my work network to access the core application server. The web server has a self-signed, untrusted certificate.
Windows PC: Windows 10 laptop connected via wire to the network. Certificate error is ignored by the user in Chrome and the webpage comes up.
Windows Tablet: HP tablet running Windows 10 connected wireless to my network. Certificate error is ignored by the user in Chrome and the webpage comes up.
Android Phone: Google Pixel 3 connected via WiFi to my network. Using Chrome, connection times out.
I've try a couple of Android devices and an iPhone, and neither connect. I'm not sure where to begin debugging this. I know it worked last week because I tested the configuration to prepare for testing this week. Any blaring issues to look at, other than perhaps a code change that broke the mobile rendering?
What is the way of your Windows Tablet connected the network? Is the wireless connected way the same to Android Phone? in other words, using WiFi too?
I doubt if your Wifi network works like before. Check your IP of the Android Phone, then Ping the IP on the webserver, and confirm whether the network with the target web server is unobstructed.
Alternatively, we Ping the gateway of the network on both an Android phone and the website.

Feel free to let me know if there is anything I can help with.
Good afternoon. Please help in creating the application.
A project is being created to control the air suspension of the car through Arduino. The application is written in App Inventor. The connection must be established via Wi-Fi.
Q: how do I do this in App Inventor? What are the blocks? So that when you start the application, it is immediately connected to Wi-Fi.
I don't think it's necessary to auto-connect your Android device to WiFi. The connection over WiFi method is much user-friendly to connect it manually. But, if you intent to do this, you could use TaifunWiFi.
hope this help.
For example, if I have a friend over and he wants to show me a video using a given app that runs both on my device and his device. Could that app display a QR code on the screen or something that he could scan and instantly be granted access to my Chromecast device?
As Ali mentioned, Chromecast devices are discovered and apps launched via local network applications. One an app is started, it could easily connect with a cloud service that allows other (non-local) devices to talk w/ your Chromecast via the cloud service. A Chromecast Receiver application is just a HTML5 application (HTML, CSS, and JavaScript). You can really do what ever you want once your application gets launched.
If displaying a QR code that allows some kind of rendezvous with your cloud application is what you want to do, you can certainly do that.
I presume your friend's mobile device is on the same wifi network, right? Currently, a chromecast device has no identity outside of its local wifi network, so if the sender is not on the same network as the receiver, there is no way they can exchange messages. Back to your question, if your friend is on your network, then he could see your device except from those applications for which your device is not whitelisted for. Is that the case you want to handle through, say, a QR code? If so, that is currently not doable either since whitelisting is not just a local setup. Maybe I misunderstood your question?
Based on your questions, you are saying that both you and your friend have the same app. If so, and if your friend connects to your wifi network, then he will see your chromecast (you do not whitelist a device for a phone, you whitelist a device for an app id and as long as your friend has the same app (hence the same app id I resume), your whitelisted device will be discoverable by his phone. On the other hand, if you do not want to give him credentials to get on your network, then you need a cloud backend and a lot of work, since although your chromecast device can send a message to cloud and your cloud service can notify the other user's phone (using, say notification or some other mechanism that you employ in your app), the reverse (i.e. sending a message from your friend's phone to your chromecast (through your cloud service)) is much harder. Your friend's phone can send your phone a message (again via a back end service, a bluetooth communication, NFC, etc and then your phone using your app can send that to the chromecast receiver but I am sure you are getting the idea that it is a lot of work. Signing up on your wifi network can be made easier with a QR code or something so at this pint, that would be the easiest solution.
I am using Sample App of Bluetooth Chat.I Have one problem I want to search only those devices on which "BluetoothChat" is installed. Please help I am new in android.
It can't be done. All you can do is try connecting them all, if the connection is refused, you will know that this device is not running your app.
That is not possible.because you did not check package name of your application in another device before connectivity via bluetooth.If you want to connect only tab or mobile device then this can easily possible.
