I just spent the day looking for what the limits are for Android v4.3 limit on the BLE connection parameters.
Such as:
-Interval Min
-Interval Max
-Slave Latency
-Supervision Timeout
No luck, Apple is nice enough to document all of these in their Bluetooth Design Guidelines, but Google hasn't been so nice.

View 1 Replies View RelatedOften times "like aboard an airplane" there's someone you want to talk with, but can't, because they're in a different seat. Is there any app that would allow people to:
a) send messages to other Android phones via bluetooth
b) sent messages by connecting to a common wifi network (yet not connected to the internet)
c) create an ad-hoc network and send messages that way.
Would any of those be feasible at all?

I'm creating an application that uses an android to send and receive data via bluetooth. but I'm having problems when creating the socket. He gets caught in that line mmSocket btserver.accept = (); And I can not pair with any device.I have another doubt, I can make that communication with an android and a symbian?
View 1 Replies View RelatedI have had my Incredible for one week. Paired it with my car with no problems. Today it started losing the bluetooth connection. I turn it on and with 15 seconds, it turns off. It will pair with my car but than disconnects when the bluetooth turns off. Took out the battery and that did not work. Anyone know what could be the problem?
View 3 Replies View RelatedI have program that runs a bluetooth connection. The socket connects fine. We then read/write from the related streams. This works fine for about a minute, then we start to get IOExceptions from the InputStream.available() and OutputStream.write() functions. The IOException indicates that the socket has been closed. Could anybody take a stab at what might be going on here?

View 2 Replies View RelatedI always had windows mobile devices in the past, and like you must know, the old good windows mobile no longer exist... Microsoft killed it.
So I switched to Android. I really like android, The way it works is pretty the same than windows mobile with file browser, files system(Not like the Iphone without any way to deal with a file at all), .APK install like the .CAB on WM...
One think that I loved on WM is how easy it was to make shortcut by yourself, even with parameters. As example, it was easy to create a shortcut to Coreplayer to play an HTTP stream when simply clicking on it.
Like: "coreplayer.exe my_teststreamDOTcom : portNumber"
I'm having an issue here while trying to connect to an RS232 device with the BluetoothChat sample program.

I thought it would be quite easy to develop a bluetooth application on Android, but it looks like the support is very bad. While pairing works, my Nexus One with Android 2.1 can't connect to the PC. It's the same in Windows and Ubuntu. I used on my Desktop computer, in Windows, Hyperterminal and waited on an incoming bluetooth com-port. I searched already a bit, Maybe this:

or this library:

View 2 Replies View RelatedIn my understand, Anroid app supports only SPP connection not HFP and A2DP. However, I want to initiate HFP and A2DP connection in Android app just like selecting Bluetooth device in Bluetooth Settings menu. I'm not sure it is possible to use a intent including BluetothDevice object, so the intent receiver can initiate HFP and A2DP connection. If you have a idea, could you let me know that?
View 1 Replies View RelatedI've uncovered what could be a serious problem with the Desire. It's only affected me in one way so far, but who knows what other problems there are that I haven't found. I've noticed on several occasions that when listening to music via Bluetooth, my headphones disconnect for no apparent reason. However I've found a pattern now: if WiFi is turned on and I come within range of a /remembered/ hotspot, the WiFi connects and BOOM, disconnected from audio. I can reconnect straight away. There is another poster here (sorry, can't remember your name or the thread you posted in) describing another problem with WiFi and Bluetooth working - or conflicting! - together so I don't think I'm the only person suffering. Who else can reproduce it and how could I submit a bug report to HTC?

View 3 Replies View RelatedI'm not sure if this started after the update, but every time I use WIFI and Bluetooth, my WIFI connection dies less than a minute after using it. For example, I'll connect my Bluetooth headphones and then start up a streaming music service. In less than a minute, the music stops and my wifi connection is dead (even though it says it is still connected). Can't browse the web, do speed test, etc. Have to disconnect WIFI and reconnect. But it will do it again as soon as I start using the connection.If I turn off Bluetooth, my WIFI works just fine. If I use Bluetooth over 3G, it works fine. It's only when I use both WIFI and Bluetooth and when I start using the Internet.I'm thinking it's either a bug or an interference issue between the WIFI and Bluetooth radios? Sometimes the music will cut out a bit before the WIFI connection totally dies. But if I switch over to 3G, it works fine. I tried several apps too, not just the same music streaming service, so I know it's not the app. Here's the weird part: if I use my Bluetooth headphones while connected to WIFI, but only listen to music that's on my device, it doesn't do it. It's only when I start using the WIFI heavily that it does it.Anyone else experience this? As it stands, I cannot use WIFI and Bluetooth at the same time.

View 5 Replies View RelatedI was trying to use my PC's LAN Shared Internet on my Samsung Galaxy S using bluetooth internet connection sharing. The settings are correctly provided on my laptop. However, Samsung Galaxy S's bluetooth doesn't seem to be able to recognize this. i.e., Galaxy S doesn't have a network profile, due to which it always connects to my Laptop for headset service. Is this a limitation of Galaxy S? Can't Galaxy S connect to bluetooth for network sharing services?

View 1 Replies View RelatedWhen my Bluetooth application is about to create SPP connection to the unpaired remote device, pairing notification is displayed. From the documentation I can see that pairing request can display a dialog or sent notification. I'd like to know what logic causes my app to sent notification than display a regular pairing dialog. Maybe I'm blind but the problem is I were not aware of that notification and was fighting with pairing problem for few hours :) And I'd really would prefer my app to trigger dialog display.
