An application to sniff a Bluetooth communication between a stethoscope and a computer - bluetooth

I have to access at sound record in a digital stethoscope. But I don’t access directly to the record sound. I have to use a propriety application.
Someone knows software to sniff the Bluetooth transmission between the digital stethoscope and my computer. I need that to understand if I can program my application in Java to communicate with the stethoscope.
Thank you.
Best regards.
Daniel

using external bluetooth transmitter without sound card

The sound card in my desktop tower is busted. I am planning to get an external Bluetooth device so that I can connect external sound devices. I am trying to do some research on this matter to find out if it will work before I commit my resources. Please help if you have resources that can explain if this is possible and I could add to my knowledge. Please Help!

MITM Bluetooth SPP server

I want to figure out the protocol between 2 Bluetooth devices (BT, no BLE). I know they are using SPP as I can use https://github.com/eelcocramer/node-bluetooth-serial-port to connect to the slave.
I was wondering if I could do a MITM attack by emulating the slave so the real master connects to me and to pipe the data through to the real slave?
Does such a tool exist or should I write one myself?
Thanks,
Sam
To answer my own question: YES, it is possible. I successfully did a man-in-the-middle attack using btproxy. I also used bdaddr to spoof the MAC address.

Is there a way to connect to iBeacon while my Bluetooth device is invisible?

I'm researching iBeacons. Can I connect to iBeacons while my Bluetooth is invisible (to be protected from hacks)?
I don't have beacons to test myself and can't find any clear explanation online.
iBeacons connect to mobile phones using Bluetooth, so it is essential to have that turned on. You also need to have installed an app with iBeacon support in order to receive communication from them.
If you'd wish to use a solution that does not utilize Bluetooth, you could try out IndoorAtlas. It's an indoor navigation technology based on Earth's geomagnetic fields. It's also completely hardware-free solution, just requires you to collect fingerprints in the area you are going to use for your project.
Three points:
iBeacon technology does not rely on a bluetooth connection to your phone. Beacons are one way transmitters. They do not listen to or otherwise receive any info from your device. Beacon technology following this model is inherently privacy friendly.
Mobile devices cannot detect Bluetooth beacons with the Bluetooth radio turned off. Sorry, it is just not possible.
Properly built beacon apps will not expose your mobile device's Bluetooth info because they are receive only. Of course, other apps on your phone might use bluetooth for other purposes, so your best bet is to audit apps using bluetooth and remove any that are not doing what you want.
I just bought some beacons and tested that, The answer is YES. it is possible to read beacons mac addresses while using the phone's Bluetooth connection as invisible. Using this you will get access to your beacon in any open place without getting hacked through Bluetooth.
Thanks all for your answers.

Custom UUID for bluetooth using bluez

I'm trying to pair my iPhone with my ubuntu computer over bluetooth. I'd like to use CoreBluetooth. I have bluez configured correctly, but I need a UUID for CoreBluetooth to connect to my computer. How do I go about setting a custom UUID in bluez?
Ultimately, I'd like to send commands with my iPhone to my pc and then use https://github.com/eelcocramer/node-bluetooth-serial-port to access the transferred data. Is there a better way to do this? I'm new to bluetooth.
Does your computer supports bluetooth 4.0? You can search for
[centralManager scanForPeripheralsWithServices:nil options:nil];
and every reachable device will be found.
With your other problem i can't help you sry.
You need to use bluetooth classic not the low energy for serial port communication

Tools for bluetooth monitoring

For my project I have an Android phone and an Arduino device that communicate via Bluetooth. I was wondering if anyone knows any software tools I could use to monitor a bluetooth communications between two devices. Something like a packet eavesdropping. Preferably for Linux.
Take a look at ubertooth one. In the linked webpage there are instructions on how to build the dongle, as well as links to shops selling assembled dongles may be bought. Ubertooth one should work well with Kismet, and thus in Linux, by using a BT plugin (disclaimer: I have no personal experience on this).
Sounds like you are after a Bluetooth sniffer.
Bad news: They are almost exclusively Windows OS based and cost mega-$.

If you were using BlueZ for one side of the communication you could use the BlueZ HCIDUMP app and Wireshark.
I don't think anyone has made a Linuz/Bluez Sniffer - could be wrong.
