Im developing a mobile application in j2me.In my application i connect the mobile with some other device with respect to bluetooth.After connection established i send the command from the mobile to that other device to perform some operations via bluetooth.
Here i does not know how long bluetooth connection remains.Im using javax.bluetooth package.
So please tell me how long (with respect to seconds/minutes,etc) bluetooth connection is remains after connection establishment,Or is there is any bluetooth connection time out in mobile/j2me.H
Here im using nokia s40 series is my targetted device in mobile side.
Im fresh to bluetooth technology.So please forgive my mistakes in the questions.All of them are welcome to provide their ideas.
Thanks and regards,

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'm working on Bluetooth on the embedded Linux. I'm using BlueZ and D-Bus. I have a server taken from the example https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/test/example-gatt-server.
I have the app such as nRF installed in 2 iPhones. I'm able to connect to my Linux Bluetooth server at the same time. I'm able to modify the characteristic from either of the iPhone app. But this is a problem because we don't want it. We'd like to have only 1 phone connected to the Linux device. That way, the same characteristic won't be modified by more than 1 phone app at the same time.
Is there a way to allow only 1 connection to the Linux Bluetooth GATT server at any given time?
Thanks.
Yes, the way to do this is to disable/stop advertisements on your Linux device as soon as a connection is established. This way, upon a connection, your Linux device will no longer be advertising and remote devices will no longer be able to connect to it.
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.
I am writing a Tizen app (web app/Javascript) for Samsung Gear S2. I am trying to send XHRs, and this works fine as long as connected via WiFi. However, when connected to my phone via bluetooth, there is an error and the connection can't be established.
I have read different information that this might not be possible at all / not be possible due to an SDK bug / only possible when routing the information through an Android app on the phone / etc.
Does anyone of you know what the issue is and how it may be solved?
Thanks!
The bluetooth interface is managed by the SAP (Samsung Accessory Protocol) and you could the SAP SDK to achieve what you want.

I need to establish a bluetooth connection between two devices so that the data can be send/received continuously. I am new to j2me and under the 'learning and implementing' phase.
So if anyone can suggest me an easiest way to get how to establish bluetooth between two mobile devices.
It can be a tutorial or a blog or any kind of reference site.
There is a bluetooth API demo application in the J2ME SDK. I would advise reading the source code it contains first.
