My Raspberry PI3 looses the Built-In Bluetooth connection after a few seconds.
I´m using it with Gigaset G-Tags but it is not stable. Does anyone have an idea? I did update & upgrade. The distance of the G-Tags is just 3-5m.
I want to use it as a presence control. Does anyone have an idea what i could try?

everybody!
I'm trying to connect my raspberry pi 3 bluetooth to my headset. However the sound bug. It's kind of intermittently cutting off quite randomly, which makes it sound terrible.
I'm using the Raspberry 3's built-in bluetooth with Pulseaudio on Raspberry Pi OS V4.19.
How do I fix it?
This sounds like the known issue. You might want to follow some of the issues that are open around this topic:

I'm working on a project where a Raspberry Pi 3 runs a python server which controls some arduino's that are connected to the same router via a switch. I'm using a websocket to display a GUI in my browser.I need to be able to use the gui over my primary network connection which has internet acces. The situation looks like this :
The problem is that I can't get both WiFi and Ethernet to work, just one at a time. This has mainly to do with running Stretch, but downgrading is not an option. On older Raspbian version's I could use the allow hotplug or auto setting in the interfaces file to make sure both interfaces are up. But I've heard you should not touch the interfaces file on Stretch. Can someone tell me how to do it ?:) Thanks a lot!
I just bought a JBL speaker, tested it on my phone and proceeded with this tutorial on my Raspberry Pi:
https://www.raspberrypi.org/magpi/bluetooth-audio-raspberry-pi-3/
I managed to pair and trust the speaker, but I can't connect to the device from bluetoothctl, only from audio settings.
Problem is, most of the times it doesn't work. I've managed to have audio for 3 seconds in a timespan of ... 4 hours.
This is where PulseAudio crashes:
E: [pulseaudio] bluez4-util.c: org.bluez.Manager.GetProperties() failed: org.freedesktop.DBus.Error.UnknownMethod: Method "GetProperties" with signature "" on interface "org.bluez.Manager" doesn't exist
I've tried a lot of things from forums, nothing worked.
Thank you for your help!
I had a similar problem, but then I used a USB bluetooth adaptor for connecting to my speaker, and now I get a nice stable connection all the time.
I can't be 100% sure that this will fix your problem, but give it a try. It seems that the built in bluetooth adaptor for rasp Pi 3 isn't great. I used an Asus adaptor, but if you need to buy one, you can find a list of the officially supported adaptors # https://www.raspberrypi.org/.

I am doing my master thesis and one of the important things for me is to transfer the recordings of pressure and temperature from a patient simulator to a PC. From the sensors, the information is taken by the raspberry pi3. I am using raspberry pi3 because it has inbuilt wifi option. Now I have to transfer the data from the raspberry pi to the PC wirelessly using python programming. I am new to python and I have absolutely no idea how to do this. Could anyone help me with writing the code so that I could at least send some data from where I could adjust the bit rate and other things according to my requirements?
Take a look at sockets, a simple client - server communication is really easy to do :)

I am developing project on Raspberry Pi and I need to add feature of measuring heart rate. I want to use Smart Watch to do that but I do not know which smart watch provide environment which allows me to implement wireless communication between watch and Raspberry (Raspbian OS) easily. Thank you in advance for each answer.
I don't think any smart-watch allows direct connection between Raspberry Pi and smart-watch. It is not recommended on android developer site to open lower level sockets as well. You can send smart-watch's sensor data to Phone and then send it to Raspberry Pi.
