Hi,
what is the function of "Bluetooth DUT mode"-switch in diagnostic tools bluetooth-section?
Thanks in advance
Donpromillo
DUT stands for Device Under Test
You can verify and record timings for Bluetooth RFCOMM data transfer using various buffer sizes while your device is in DUT mode.

Hi!
Hi have bought the bluetooth headset Globalsat BT-808 (Mini Dolphin) and it is a great product! I use it with my Qtek 2020 to make and receive calls. I wanted to use it with my mobile computer as a headset audio device via BT. I paired the BTH-808 with my computer BT adapter (Microsoft XP SP2) as AUDIO DEVICE... but if I try to change the default audio device on my mobile computer (a Realtek AC'97 on the mainboard) and try to select another device, there isn't the BT headset... only realtek! How I can add the BT Audio Device from the BT paired devices among the PC Audio devices available???
Thank's
Cristian
First enable the audio gateway in the bluetooth application on your PC. After this it should be possible to choose the audio gateway as BT audio playback device.
You have to connect manually to hear the audio. The connection isn't made automatically.

Click to expand...
Click to collapse
And How to enable the Audio Gateway? Please tell me where I can find the option in BT Stack from Microsoft XP SP2 drivers...
Thank's

here is a list of the bluetooth profiles to get sereo audio to a bluetooth headset you require A2DP 0.95b Advanced Audio Distribution Profile
not sure if thats the same with mono audio
but i do think it rather likely that ms's default driver dont support many profiles at all
i would look into bluetooth software like vidcomm maybe you can install that it's bound to have more profiles then ms
ms dident invent bluetooth so they dont put a lot of efford into supporting it

Hello! I'm thinking about this by a while. Actually the Android MIDI software you can find on Google Play use MIDI over IP or rtpMIDI technologies to send the MIDI signal via WiFi. Knowing how a network works, specially the wireless one, I think it's a waste of _time_. I thus thought why not passing the signal over USB? That's not a problem, just create a peer program on the target machine and comunicate via sockets or similar - not. My idea is to setup the application so that the target computer can see the MIDI device with no special drivers or programs or hacks (MIDI over USB is a standard).
Is it possible then to let the Android device be seen by the computer as a MIDI device, or at least "even" as a MIDI device?
Thanks.
I've bought this earphone
http://www.planex.co.jp/product/bluetooth/bt-minihs3/
This is google translate section on the BT compatibility is:
"Bluetooth Ver.3.0 next-generation standard, I realize the connection that stability correspond to the (Enhanced Data Rate) EDR, a high-speed capabilities of Bluetooth. The communication of up to 10m is possible by Class2 support. Because there is also compatible Bluetooth Ver.1.1/1.2/2.0/2.1, communication with existing equipment is also available."
So the earphone should support BT version 1.1 up to 3.
Now I turned on the earphone, enabled BT on the x10mp and pressed "scan for devices". but the mobile doesnt detect the earphone.
any suggestions?
TIA
bumping. anyone?
Hi
We have an android application which uses UsbManager to get GPS data (over a USB port) in cubie board. We use another USB port in cubie board for 3G dongle (which is driven by 3rd party apk from play store).
3G dongle is not fixing when I we install the apk which receives GPS data over USB. What could be the problem? I am just iterating USB devices and connecting to only the GPS device. Is it because I am iterating all the USB devices?
How to make 3G dongle working?
How do I get the required Device object without iterating and find the device by vendor id? I am doing this just to request for user permission. I am not doing this then I am not receiving the message in Broadcast receiver which connects to USB device.
Thanks

Hello everyone!
First of all, I'm new to this forum and I hope I'm on the right section.
I am developing an Android app that uses USB in host mode. The USB device can stream audio (both playback and capture), but can also send/receive other data (no more than a few bytes) in interrupt/bulk mode.
The idea is to use USB Audio driver provided by Lollipop for audio, and the USB methods provided by the SDK for the other data.
When using Lollipop's USB audio driver, the OS "automatically routes audio playback and capture appropriately". However, the documentation (source.android.com/devices/audio/usb.html#hostApplications - sorry for the link, as a new user I can't post external link) also says that "the automatic routing may interfere with applications that are USB-aware".
I tried the automatic routing and it works. The problem is the following: when Android captures or plays audio, it seems that all the data sent/received in the same direction by another way are blocked (like interrupt ones, through the SDK). That is to say, if I play audio from the smartphone, I can't send any other data to the device (and if I capture, I can't receive).
Additional information:
The bandwith is not an issue: I succeeded to receive both "audio" and data using Libusb in isochronous mode for audio and the SDK for other data. But I can't write an entire driver for USB Audio with Libusb, and I'm not sure that a simple isochronous transfer does the trick correctly.
The device is recognized by a PC both as a microphone and a speaker, so this is not a device issue.
The phone is not rooted.
Is there a way to solve that?
Also, assuming I can use the Lollipop's driver, does anybody succeeded in sending and receiving audio at the same time?
Best regards,
Victor
