This method is fast, and could be used to transmit measurement values in real time.
A custom service and characteristic is used.
A phyton script is supplied :
* the scrips scans for a specific device (since bluetoothmac is variable : a bit like DHCP in netwerk traffic)
* once the device is found, it switches on “notifications” and listens for incoming messages.
BlueZ running on the host, or
