I actually work on a raspberry Pi with a bluetooth dongle and I need to create a bluetooth server on that devices.
I want to be notify when an other devices is pairing with the pi.
So I use the bluecove library.
I think this kind of thing isn't implements into the library.
It's there a way to do that ?
Thanks.

I never used a raspberry pi before and I have a project part of which includes receiving data from a BLE blood pressure device over Bluetooth to a raspberry pi 3. I can pair the device to my raspberry but I have no idea what to do next. I need to be able to receive the measurements in my raspberry please help and thank you in advance.
PS: the device I'm trying to use is very similar to this one:

Thanks for your answers, I have tried "Gatt" and "Gatttool" but the problem is after pairing the device is meant to send the measurement to its application on an android phone, without it I cannot read the blood measurement characteristic or it just does not exist.
Linux uses BlueZ as a default bluetooth stack. It exposes DBus APIs for implementing software using Bluetooth.
If you don't want to use this API directly, which can sometimes feel a bit low level you have many libraries that wrap it, such as https://github.com/getsenic/gatt-python that also comes with examples.
All other solutions requires replacing the Bluetooth stack on Linux and hence your other existing Bluetooth pairings to the system will stop working.
In my current project, I am working with iBeacon in the area of IoT. Basically iBeacon works on Bluetooth wireless technology. I am using Raspberry Pi 3 (which is available with in-built wifi and bluetooth). Pi 3 Bluetooth display and detect the iBeacon but not able to do pairing with it and display the following error:
GDBus.Error:org.bluez.Error.AuthenticationFailed
I also tried with bluetoothctl command also but again display the Failed to pair: org.bluez.Error.AuthenticationFailed
error.
Am I missing something? I am able to pair iBeacon with my mobile and windows based lapotop.
Understand that iBeacon is a transmit only Bluetooth LE device. It is Bluetooth LE manufacturer advertisements to send a unique identifier, something you have seen if you have detected it with the Raspberry Pi 3.
But a basic iBeacon device is not designed to be connectable over Bluetooth LE. Some beacon manufacturers may expose a secondary configuration service that is connectable, but this is not universal and if it exists it is entirely outside the beacon spec.
Bottom line: you are not supposed to be able to connect.
If you have a specific model of beacon that does have a config interface, and you want to connect to that, you may want to put that in your question.
My knowledge in both bluetooth beacons and Arduino is limited at this point.
This is for an indoor positioning system I'm thinking to develop. Is it possible to create an Arduino board where the BT module receives a BT beacon ping with the Beacon ID, and then relays this data to a Wifi module on the same board, to then send it out to a server/local server of some sort?
Is this feasible? Or is it even possible the receive the ID of the beacon using Arduino?
I've attached an image of what I was thinking of:
Yes, this is absolutely possible. I have done the same with a Raspberry Pi. I am not an expert on programming the Arduino but I know for sure that both parts (beacon detection and decoding) and calling a web service over WiFi are possible with the Arduino.
I need do communicate atmega88 with a smartphone via bluetooth using a bluetooth HC-05 module. The problem is that all my atmega pins are being used. Rxd and txd pins are being used by a keypad (Keypad at PORTD). My project is almost done, at this stage i don't want to change the micro. Is there any alternative to solve this problem? Thanks
You can use Software serial library for that controller. But it is better to connect HC-05 module to default UART pins.
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
