BLE - NUS and characteristics

[Roei]

Hi,

I'm little confused regarding BLE NUS and characteristics.

I know that the characteristics are used to expose data, but we also have BLE nus which is used to send and receive data.

Is there any connection between them?

Do they use the same way to send and receive the data?

Thanks!

Does discovery service related to NUS or device information service? Or is it a separate service which doesn't need to be declared?

Thanks!

There is no separate 'discovery service', the service discovery is a process for discovering what services that a connected device provide and support.
