How to set service name ?

[Entretoize]

Is the service name needed to be "Unknown service" ? I don't see any source setting the service name or having several services, so how to recognize the good service ?
Thanks

Afaik "Known" Services are only those defined by the Bluetooth standard, i.e. the Bluetooth SIG assigned numbers (https://www.bluetooth.com/de/specifications/assigned-numbers/).

You can however set the device name (BLEPeripheral::setDeviceName()), which is the device name under which the peripheral appears during advertising and you can set the local name (via BLEPeripheral::setLocalName()), which is shown after you have connected to the device.
