BLE NUS - TX CCCD discovery

Hello,

I'm trying to retrieve data from a nrf51822-based board that supports the BLE NUS sevice (using the ble_nus Library provided for the uart communication example, and the s110 softdevice). I have a few issues using it:

When I try to discover services from the Master Control Panel, it stops at the TX CCCD (Client Characteristics Configuration); and after a few seconds, the connection drops. If I try reading that CCCD, the same thing happens. However if I enable services, then everything works fine, and I can read the CCCD without any issue. Is this a normal behaviour?

NB: I want to interact the board with a software running on a computer using the Master Emulator API. I'm getting exactly the same issue when I try discovering the services from there; I can get the communication to the board to work, but the notification process does not seem to be activated and thus I cannot get any information to be sent from the board.

Thank you.
