NUS vs Virtual COMM port

[jbishnu]

What is difference between the NUS and virtual Comm Port? Could you please provide with example and their use case or usage?

Hi Jyotirmay,

- NUS = Nordic UART Service ("what is NUS"?)

- "Virtual COM port" is a CDC ACM USB class, but for nRF52 DK it uses the UART interface through the virtual COM port to route the signals to/from the computer. 

So you can read out the data sent through the UART on a Serial Terminal on your computer.

 

You can check out these two examples showing of the difference: UART/Serial Port Emulation over BLE and UART peripheral.

Check the links for more information and report back if something is unclear.
