Re: Bluetooth LE and Python

Are you certain the app is using BLE? Is it sending notifications? I posted some simple Python code for reading notifications somewhere.... Here it is: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=193923&p=1232385#p1232385 It's using Ian Harvey's excellent bluepy library. Read the docs fo...

Re: [Guide] Pulseaudio 5 on Wheezy

Unfortunately, Blueplayer was not exactly written to be importable. You would need to remove the mainline code, import what's left (just the classes) and then repeat what was the mainline code (instantiation and initialization) in your own code. Also, Blueplayer runs in a gobject loop, so you might ...

Re: Bluetooth Speaker Music Sound Works But Not Live Voice Call

I'm not familiar with Twinkle, but it sounds like it's bypassing the ALSA audio system. Audio routed to ALSA should play on the default device, in your case the Bluetooth speaker. You might want to contact the Twinkle author(s).

If you use public transportation, and there is a suitable API in your area, a nice feature might tell you when the next train/bus is arriving.

No, Blue Dot uses strictly classic SSP communications. A fine program in its own right. You gotta love an app whose only interface is a big blue dot.

Re: Detecting a Tile

That looks like code from the PyBluez Python module, which, as you've discovered, does not support BLE. You're going to want to look into Ian Harvey's bluepy module, which does support scanning for BLE devices, if memory serves, by way of a Scanner object.

Re: How to connect Bluetooth on my Pi3

It depends on how you would like to connect. For a Serial Port Profile connection, you'll need to enable SPP, and then run rfcomm to create a virtual serial port. If the Hi Fi remote is BLE, that's very different. You can search this forum for instructions on SPP and rfcomm.

I'm afraid I have no experience with node red. Perhaps, with some more details of what you've done and how it isn't working, someone else could provide more help. I've played around with an HM-10, but that was in Python.

1. Tested without problems. See my response to your other post. 2. You can use the Serial Port Profile to transfer data in real time between a Pi and an *Android* phone. Search this forum for instructions. 3. Using SPP you have the option of several standard baud rates, comparable to regular (wired)...

Re: BLE devices with no names

Sure, as long as you know the sensors you are using supply their name. You could also query the devices and filter by the services they offer, maybe.

Re: BLE devices with no names

It is mandatory to have a GATT service to expose the name of a BLE device, but it is NOT mandatory for a device to include that name in its advertising packets. I would not ignore devices that are not advertising names without knowing more about them. On the other hand it's not clear what you are tr...

Sorry, I missed your post last week. Basically, you'll need to do three things on the Pi: 1. Enable the SPP profile.

Re: How could I conntrol my hardware via bluetooth

You'll need hardware and software that can convert your sensor data to Bluetooth data, and broadcast it to the Pi. A simple, common, cheap solution is to use a microprocessor, such as an Arduino, along with a serial Bluetooth module, such as an HC-05. You can also find dev boards with a microprocess...

Re: Bluetooth adapter NOT found Raspberry Pi 3

That response indicates that no HCI (Bluetooth) device can be found by the operating system. Could be a hardware error, and the Bluetooth chip is toast. Not likely, especially if WiFi is working. More likely is that the hciuart.service didn't run. Either it's missing, or encountered errors. First th...

For connecting to devices using a 'random' address type, bluepy has an equivalent parameter to gatttool's '-t random' flag. I believe the syntax is thus: peripheral = btle.Peripheral(deviceAddress, btle.ADDR_TYPE_RANDOM) I believe bluetoothctl will attempt to connect to both public and random addres...
