serial port library

[Stas]

I confused a little about serial port library example. Can I consider this like software uart example similar to arduino softwareserial library?

Hi,

The SoftwareSerial library in Arduino implements UART in software("bit banging"). It has several known limitations, e.g. if using multiple software serial ports, only one can receive data at a time.

The Serial port library in the SDK is designed as a more sophisticated replacement for the app_uart module, with Multi-instance capability, configurable buffers and more robust and generic API. It does not implement any “software” UART. The Multi-instance capability in the serial port library is very useful in e.g. the nRF52840 where you have 2 hardware UARTE instances.

still two.
