Can an Android phone be used as a Bluetooth headset/speakers?
Is there a way to make an Android phone (HTC Desire HD) act as Bluetooth speakers or headset? I’d like to use the phone as wireless headphones whilst watching a movie on a computer (running Ubuntu).
It looks like there are several apps that can do wireless speaker (over Wi-Fi though, not seeing any that do bluetooth), but none so far that do wireless headset. This Wi-Fi speaker app advertises Linux support: play.google.com/store/apps/…

As of Feb 2011, the Bluetooth API only supports pairing with the Android device as the master.
Comment by Dennis Mathews to the linked answer — Anyway being a master or slave has nothing to do with what it can or cannot do, the roles in bluetooth are symmetrical — it is the supported profiles that determines what it can or cannot do
Partially solved, because newer APIs can perform it in the future, or specific APIs or some kind of hack can perform it.
Here’s a XDA article by Mishaal Rahman that basically says:
Even without A2DP profile on Android (which is not implemented even in Android 8 yet), you can do a low-quality Bluetooth streaming via Hands-free Profile (HFP) to Android from another Android phone (sorry iPhone owners!)
Install Tasker and a AutoVoice plugin on the source phone, and create the following Tasker profile:
Profile: Reroute Audio (192) State: BT Connected [ Name:BMW 15384 Address:* ] Enter: Anon (199) A1: AutoVoice Ctrl BT [ Configuration:Enabling Headset Sound Timeout (Seconds):0 ] Exit: Anon (204) A1: AutoVoice Ctrl BT [ Configuration:Disabling Headset Sound Timeout (Seconds):0 ] Warning: I have not tested this myself.
Warning: quotation about HFP audio quality:
Note: because the Hands-Free Profile is not meant to send high-fidelity audio streams, the audio quality of your music will suffer. This is just the nature of the Hands-Free Profile and there’s nothing you can do about it without either upgrading your stereo’s Bluetooth to bring A2DP support or to stream through another peripheral.
Transforming Your Android Phone into a Bluetooth Headset: A Guide
An alternative approach, as not every phone supports using an Android device as an , is to construct these two applications through your wifi network. To accomplish this, you must incorporate the HFP profile into your Android device, with the phone role typically being AG (Audio Gateway) and the headset role being HF (Hands-Free). Think of it as a server-client relationship.
I am aware that Android has included the bluetooth headset Profile, however, it functions as an Audio Gateway Role rather than a Headset Role.
My plan is to create a Android phone app that functions as a bluetooth headset. This way, I can link it with my laptop via bluetooth and use my phone to call someone. The app will transmit the sound through bluetooth to my laptop, which will then forward the data to a separate program such as Skype, GTalk or another VoIP program.
Could you please suggest a way to enable the Headset Profile on an Android phone in the Headset Role? Your help would be greatly appreciated.
Regarding the Android aspect, I believe the optimal approach would be to initiate a connection to the service on your computer.
URL url = new URL("http://192.186.0.1/path/to/service"); URLConnection connection = url.openConnection(); Get it as an OutputStream:
OutputStream out = new BufferedStream(connection.getOutputStream()); After recording the data, transmit it by utilizing the AudioRecord function.
public static final int DEFAULT_SAMPLE_RATE = 8000; private static final int DEFAULT_BUFFER_SIZE = 4096; private static final int CALLBACK_PERIOD = 4000; AudioRecord recorder = new AudioRecord(MediaRecorder.AudioSource.DEFAULT, DEFAULT_SAMPLE_RATE, AudioFormat.CHANNEL_CONFIGURATION_DEFAULT, AudioFormat.ENCODING_DEFAULT, DEFAULT_BUFFER_SIZE); recorder.setPositionNotificationPeriod(CALLBACK_PERIOD); int bytesRead = 0; ByteBuffer buffer = ByteBuffer.allocateDirect(DEFAULT_BUFFER_SIZE); while ((bytesRead = recorder.read(buffer, DEFAULT_BUFFER_SIZE)) > 0)
To prevent the app from crashing, it is essential to perform all the above tasks on a separate thread. Additionally, a system must be in place to manage situations where the recording ends or if the connection is lost. Although Bluetooth-enabled devices now come with Wi-Fi, it is uncertain if they will operate in the same manner. It is, however, probable that the application will function correctly over Wi-Fi since it provides a higher bandwidth.
I cannot guarantee that this code will function properly as I haven’t tried it yet.
The upcoming task involves transferring the audio to the desired application via the machine, which is beyond my expertise. It seems like a virtual driver or a similar mechanism will be needed. Additionally, the opposite mechanism will have to be implemented to send audio from the desktop app to the phone. I am particularly intrigued by this aspect, as it could create a convenient wireless headset for enjoying movies.
I’d like to share my opinion and see if it proves effective. 😉
It’s unclear if I fully grasped the question or objective at hand, but I previously shared a guide on this forum regarding the process of sending and receiving audio through Bluetooth on an Android device using a headset.

I am trying to make my Android device function as a Bluetooth headset, but I am having trouble finding the appropriate Android APIs. I have only found interfaces that allow Android devices to function as masters, not as devices like a Bluetooth headset. I am willing to modify the Android OS source code and rebuild the OS. My goal is for the Android device to function as a Bluetooth headset when connected to a mobile phone via Bluetooth. I am unsure if there are interfaces that can accomplish this or if I need to modify the Android OS itself. Thank you for your assistance.
To enable the HFP profile on your Android device, assign the phone role as AG (Audio Gateway) and the headset role as HF (Hands-Free), similar to a server-client relationship. Establish a connection with the phone via RFCOMM channel using the HF-defined UUID and update the SDP record. Modifications must be made to handle AT Commands. After completing these initial changes, you must then manage the transmission of audio packets (SCO packets) for voice calls.

I possess two Android Phones devices and intend to link them through Bluetooth, with one of them serving as a Bluetooth headset.
I am wondering how to set the second phone to switch its role profile to «Bluetooth Headset» upon connecting.
Although I came across this post, my inquiry varies slightly.
Thank for any advice or idea 🙂
The built-in Bluetooth profile on Android does not allow A2DP functionality.
Your phone functions solely as a transmitter, lacking the ability to receive signals as a receiver.
Kindly take a look at my two responses explaining why this is unattainable.
Instead of creating one app that serves as both the client and server, an alternative approach is to build two separate apps with a client/server setup using a custom protocol. For example, the server app could utilize Bluetooth to stream audio content to the client app.
Given that utilizing an Android device as an A2DP sink may not be practical for all devices, an alternative solution would be to construct both applications using your wifi connection. This approach could result in faster processing and superior sound quality.

An application that transforms an Android device into a versatile Bluetooth device has made it feasible to operate a PS3 using the Android phone as a Bluetooth remote control . This link enables the phone to function as a virtual keypad to input text and includes a trackpad on the touchscreen for navigating the PS3’s web browser.
Currently in beta form, the app BlueputDroid can be a bit challenging to use. The list of Android phones it supports is not comprehensive, and some phones need custom firmware. Additionally, getting the app installed requires overcoming technical obstacles. To find a list of both supported and unsupported phones, visit XDA-developers.com, which originally introduced the app. There, you can also find instructions on downloading the app if you have an Android handset that is compatible with it.
The Nexus One and HTC Wildfire with rooted firmware were successfully tested by the independent developer. However, the LG Optimus One did not work despite several attempts.
The initial app to enable smartphones to connect with the PS3 as an input device is BlueputDroid. While there are multiple Bluetooth apps for Android that provide more flexibility in syncing with a computer, this is the first functional app for PS3 connectivity. If the developer can improve the process and increase compatibility, using phones for inputting PSN information or typing URLs would be preferable to having a physical keyboard connected to your system.

BlueputDroid is only compatible with rooted devices, as stated in EHSAN’s article titled «How to remotely control your PS3 with Android BlueputDroid Apps Guide» published on Feb. 27th, 2011. This means that if you wish to use this app, you will need to root your device.
A guide on using Blueputdroid apps to control your PS3 remotely with an Android device is available on topbestfreeapps.com.
