I need to know, if I can send Bluetooth AVRCP command using BluetoothAvrcontrollerService from an android app to a hardware which supports AVRCP profile in Bluetooth. If it is possible please provide a sample for the same. Thanks in advance.

When I press a button on a device that is connected to iOS or Android via Bluetooth, it should perform some task in an app(app installed on iOS or Android). I am not sure which Bluetooth profile will be best for my job. I think HID profile, but will it work with iOS ? Any suggestions or comments are welcome.
iOS devices can't use standard Bluetooth connection with Android. In this case you should use BLE (Bluetooth Low Energy). This means you should use GATT profile for Android. There is an important issue here: all iOS devices can BLE peripheral or central but for Android some devices only can peripheral.
I'm planning to replace the Beacon tag of my Bluetooth (BLE)-based localization System with a smartwatch. Therefore, the smartwatch has to be able to advertise bluetooth signals. However I can't find any information about smartwatches using BLE advertising methods. I actually don't want to use an additional smartphone which would be able to advertise. I already found that the iWatch and the Moto 360 are probably not able to advertise.
Does anyone know if there's (or will be) a smartwatch available that is able to advertise BLE signals?
Thanks a lot!

Ok, this is not possible for Sony Smartwatch atleast. This is because in order to be able to broadcast a BLE advertisement of your choosing, any given Android device has to be able to support BluetoothAdapter.isMultipleAdvertisementSupported(). Unfortunately, this feature is not available on most Android Wear devices.
If your Android device does support multiple advertisement, then you can create an advertisement packet and use the BluetoothLeAdvertiser object to start advertising.
I have a project for multimedia player running on WP8. Does WP8 SDK supports AVRCP that user can control playback from Bluetooth device? What APIs or events I should use to receive control events? Thanks!
From a consumer perspective WP7 OS supports BT-AVRCP 1.3 and so does WP8 OS. Based on MSDN the BT-AVRCP 1.4 profile is supported for WP8.
From a developer perspective BT-SPP is supported for direct developer reads & writes. I'm not sure if WP8 can successfully open a BT-AVRCP socket, so go ahead and try to open a socket to one and see what happens.
If you're just trying to play Audio on a Bluetooth headset, use the plain-old WP7/WP8 media playback classes and use the new WP8 AudioRoutingManager to force output on bluetooth headset.
AudioRoutingManager.SetAudioEndpoint(AudioRoutingEndpoint.Bluetooth)
I want to know if the developer team which made the emulator have some information to make bluetooth work in the Android emulator, indicate some links about it, if they have some date for release or if they'll make it works in the future.
as far as I know there is no support in the emulator for bluetooth. And I will have to teach android and bluetooth in some classes. And the students will need to code stuff and test (guess it) in the android emulator.
So I came up with a bare-bone reimplementation of the android bluetooth API on top of tcp. You can find it on here on github.
Basically, you run a tcp-server on your machine, and the emulators will connect through it.
Instead of using the classes in the package android.bluetooth, you just need to use the classes in the package dk.itu.android.bluetooth (and other 2 little modifies).
As for now it supports:
switch on/off the "radio"
discovery devices (only other android emulators)
creating bluetooth services
connecting to bluetooth services
It's not much, but until we got some more from the android guys, I guess there is nothing else around.
Hope it'll be useful, cheers!
The documented bluetooth limitation appears inconsistent with the qemu -bt option. So, how is bluetooth enabled in the emulator so the -bt options can be used, or at least to know that bluetooth is supported?
The target/board/.../BoardConfig.mk having "BOARD_HAVE_BLUETOOTH := true" doesn't provide a bluetooth icon or enable bluetooth. So, how do we turn on bluetooth on the android qemu emulator?
What does it mean that bluetooth is not supported given the -bt option for emulating USB devices that were provided in 2008? The post and limitations are outdated.
The functional limitations of the emulator include:
No support for placing or receiving actual phone calls. You can simulate phone calls (placed and received) through the emulator console, however.
No support for USB connections
No support for device-attached headphones
No support for determining network connected state
No support for determining battery charge level and AC charging state
No support for determining SD card insert/eject
No support for Bluetooth

I need to make an app in J2ME that can be able to read a SMS and then print it on an epson tm-p60 printer(ESC/POS emulation) via bluetooth.
i looked at the epson supprt site but the only ADK/drivers they provide are for:
1.Sun Java2 SDK Standard Edition Version 1.4.2_10
2.Sun Java2 SDK Standard Edition Version 1.4.2_04
3.Sun Java SE Development Kit 6 Update 3
so i don't know how am i gonna be able to use ESC/POS commands inJ2ME.
I'm a bit clueless on how i will approach this project.. plus w/c would be better to use for this project? Netbeans or Eclipse?
Thanks!
SPP (Serial Port Profile) over Bluetooth means using an RFCOMM connection to send and receive data as if it were a physical serial connection. This is part of JSR 82, so you will be able to develop only on handsets that support this JSR.
You need to:
Figure out how to discover bluetooth devices, and scan for SPP services on a discovered device, then connect to one of those services, using one of the many JSR 82 tutorials out there.
Then send ESC/POS protocol data over that connection -- I assume you have the protocol specification available? Google turned up this application programming guide.
HTH.
JSR-82 Bluetooth API support L2CAP protocol, RFCOMM and OBEX profile. I don't know detail of Bluetooth basic printing profile (BPP) but, if you look into basic printing profile document you can find that BPP built on OBEX profile.
I can't find open source project for BPP on JSR-82. Please try to search it, but if you can't find one you might need to write your own.
