Hi,

I'm using NRF52 and used inbuilt UART for communication with host controller.now i need one more uart port for log printing.

so how we can achieve on NRF52?

Thanks.

Why not just use Segger RTT via SWD port?

Hello,

The nRF52832 only has one UART instance. You may not use it for both logging and device interfacing at the same time.
As Turbo J suggests, you should enable the RTT_backend for the logger module, to see your logs in the Segger Embedded Studio debug terminal, or on the standalone J-Link RTT Viewer desktop application.
Configuration of the RTT Backend for the logger module is demonstrated in the ble peripheral Nordic UART example, please see its sdk_config for further detail.

Best regards,
Karl
