Main Problem
My mobile phone is already paired with my HC-05 bluetooth module. But the problem is it is not connected.
Do you have any solution about this kind of problem guys?
Need help. Thank you.
It will connect only when requested, for example, while using a bluetooth terminal application. Try searching for a bluetooth terminal app in the google play store, install, then you should be able to connect.

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 have an Ubuntu 18.04 server on a laptop that has bluetooth adapter. I also have a led strip from China which also has a bluetooth adapter. I can control my led through an app on my phone.
Is there any way to successfully connect to the led strip with my linux laptop and control it?
If so, how could I know which code / key (or I don't know how this bluetooth control works, sorry) is assigned to a color? So basically, I don't know what command should I send to the strip.
Can anybody please write an example program for me?
I tried the rfcomm, bluetoothctl and bluetooth-sendto but they didn't work. :(
Hope we can solve my problem.
You'll need to reverse engineer your device :
with little research I found this

I am trying to get a Unity3d Windows Store App game to read a string of text that is sent from an Arduino Uno Rev3 over Bluetooth.
Unfortunately, the Windows Store App platform does not allow use of the System.IO.Ports namespace, so I am not sure how to get it to read the Bluetooth data.
Does anybody know how to read data from Bluetooth in a Windows Store App?
Any help is appreciated,
Thanks
If your HC-06 has COM-port capabilities, then you can use: [https://learn.microsoft.com/en-us/uwp/api/windows.devices.serialcommunication
there is a sample on Github:
[https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/SerialArduino
To find out if your device has COM-port capability on windows 10 go to settings/Bluetooth, pair device and go to more settings, tab com-ports and try to add port. If the list is empty unfortunately you can not use Windows.Devices.SerialCommunication APIs to communicate with an Arduino device.
Another way is to use the Bluetooth GATT protocol for communication.
It allows you to read and write data and subscribe to indicate and notify events.
For this there is also a sample on github:
[https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/BluetoothLEClient
It depends on your HC-06 what Gatt-services are available but there is most likely a service that can reed and write and get notifications.
Hope this can help you,

I ended up using a BLE solution based on this example:
https://www.simplicity.be/article/eddy-and-his-stones-diy-arduino-beacon-mobile-apps/
So I've built an Arduino module with a Bluetooth chip (HM-10) and it pairs succesfully with my Windows laptop. They both use Bluetooth BLE.
The problem is that the pairing doesn't seem to open a COM port, so I have no way to actually communicate across the connection.
There are no COM port connections when I go into Bluetooth settings->COM Ports, even though Windows is definitely telling me that the pairing was successfull.
Does anyone know why this could be?
Thanks for reading

I had the same problem on a Mac. Turns out it's not a problem. BLE doesn't quite work like regular ol' Bluetooth and you won't have a COM port. You need to write your own middleware to take care of the communication between the Arduino and your computer.
There are different projects working on that in Python or Node.js. A simple google search should provide with a proficiency of solutions.
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.
