Carlo Weidinger c97710cbfd samples: Bluetooth: Improve printing in NUS sample
Removing the message buffer and printing out the message directly.
Creating a message buffer with the size of CONFIG_BT_L2CAP_TX_MTU
creates a large empty buffer, which is expensive for the stack and
can lead to a stack overflow.
This way, the sample can be more easily integrated with
other Bluetooth functionalities, such as Bluetooth OTA.

.. zephyr:code-sample:: ble_peripheral_nus
   :name: Peripheral NUS
   :relevant-api: bluetooth

   Implement a simple echo server using the Nordic UART Service (NUS).

Overview
********

This sample demonstrates the usage of the NUS service (Nordic UART Service) as a serial
endpoint to exchange data. In this case, the sample assumes the data is UTF-8 encoded,
but it may be binary data. Once the user connects to the device and subscribes to the TX
characteristic, it will start receiving periodic notifications with "Hello World!\n".

Requirements
************

* BlueZ running on the host, or
* A board with Bluetooth LE support
