Hi.

Which SDK and example are you looking at?

You probably have something in sdk_config.h still enabled.

Best regards,

Hi.

It demonstrates the use of the serial port library. This module is more sophisticated than UART driver - legacy layer. It internally uses mutex, queues, and app_timer. You can configure it to work in three different modes (polling, interrupt, DMA). API can be configured to work in synchronous mode. Both read and write methods have a timeout parameter. Asynchronous mode is available by passing 0 as the timeout parameter.

Best regards,
