What's your criterion? The fact is, we are so far away from 'artificial intelligence', the term doesn't even apply.

Re: Bluetooth not working on Pi Zero W Raspbian

It could be a hardware problem, but the chances are very small. On your new Zero, load a recent Stretch, and install NOTHING related to Bluetooth. You'll have everything you need.

If that works, try swapping SD cards, that should rule out hardware problems.

Re: Bluetooth not working on Pi Zero W Raspbian

Packages bluetooth and bluez, to the extent that they differ, are pre-installed on modern Raspbian distributions. Blueman is not needed, and could conflict; I would uninstall it. But it looks like you have deeper problems in that the Bluetooth adapter is not even recognized. As klricks says, updatin...

My two cents: I think most responders here monitor 'new posts' based on the title, and don't give a flying one about the forum it's in.

Re: cannot pair bluetooth mouse

Just to be clear, Bluetooth pairings ARE permanent. But once paired, two devices need to be connected in order to communicate. It's the connection that drops when one device is powered off. The Bluetooth GUI (or initial display of devices in bluetoothctl) will list devices that have been paired (not...

Re: New project, two motors control by using bluetooth configuration

I don't see any need for more than two Raspberries. An Rpi0w has everything you need for a 'remote' controller including the installed BlueZ stack. The main RPi can manage things (as well as GPS), and run a motor.

Re: New project, two motors control by using bluetooth configuration

What are you considering for a 'dislocated board'? It would need to be something capable of running a motor controller and a Bluetooth stack. Another Raspberry Pi might not be bad choice. In any event, connecting them with the Bluetooth Serial Port Profile is probably the easiest solution.

Re: cannot pair bluetooth mouse

Bluetooth device addresses are actually SIX pairs of hex digits, so I'm guessing the '00' is part of the address. And it sounds like it is already paired. Do this: start bluetoothctl and enter info AA:BB:CC:DD:EE:FF using the address that bluetoothctl has listed for you. If that looks good, try conn...

Re: Need help to get BLE runnung on RPi Zero W

No, you're quite mistaken about BLE. It has no relation at all to TCP or UDP, and does not support them. It was intended for transferring small amounts of data (bytes) from a very low power device such as a FitBit, watch or other small sensor, and for advertising bytes of data without necessarily co...

As I think, I can't/shouldn't spend time for code developing before the connection at the OS level works. Well, not true. To even get one device to discover another, that device needs to be advertising its presence. The procedure PhatFil linked to will get one device advertising (as an Eddystone be...

I'm afraid I've never used Squeezlite, and probably can't be of much help. If it were me, I'd uninstall pulseaudio, or start from scratch (bluez-alsa should already be installed). Otherwise, review the Squeezlite documentation.

Re: Squeezlite play on bluetooth speaker

Also remember that PulseAudio is not required for Bluetooth audio, and may possibly have messed things up.

I would uninstall PulseAudio and see the BlueALSA site for instructions to set the default ALSA device to be the Bluetooth sink.

Re: Raspberry zero w Bluetooth Auto Pairing And Sound

1. Using classic Bluetooth, you need to pair two devices before you can connect them. It is possible on the Pi to acccept any pairing request, although, for security reasons, it is not recommended. 2. Yes, again with some knowledge of Bluetooth programming, you can play a sound or light LEDs when a ...

Re: Help how to setup Bluetooth HC 05 with AT command

OK, I'm more familiar with using the Pi's onboard Bluetooth chip. Or a dongle if you're not using a Pi3 or PiZ0. Using a connected HC-05 it's simply talking to the Serial Port, which I think is now /dev/ttyS0.

Sorry, I'm not familiar with CuteCom. I haven't had any problems with minicom or picocom. Is the HC-05(6? Shouldn't matter much) connected to the Pi, or another device? A better description of your setup and modifications would be helpful.
