How to get my NRF_LOG, from macOS or iOS App or Win WM (DEV KIT NRF52)

[trdop]

Hello team,

I got a DEV KIT NRF52 And I'd like to get all my LOG : NRF_LOG_* ( NRF_LOG_INFO… ) From my USB interface Serial:

/dev/tty.usbmodem1421

I made sure that I activated sdk_config.h :

• NRF_LOG_ENABLED 1
• NRF_LOG_BACKEND_SERIAL_USES_RTT 1
• NRF_LOG_BACKEND_SERIAL_USES_UART 1

I try a simple:

NRF_LOG_INFO("HELLO WORLD !\r\n");

In my function, which I invoke

I connect to tty via:

screen /dev/tty.usbmodem1421

Here's what I get some strange characters:

/2éé&2… 

NOT my “HELLO WORLD” or whatever

I probably do not use the right method or the right program, If you could enlighten me to do it most ideally,

Thank you for your support

Hi Hung Bui,

Thank you, indeed I had not thought about the conflict of USES_RTT and USES_UART

With USES_UART only and by adding nrf_log_backend_serial.c in my project and let UART_BAUDRATE to 30801920 (115200 baud) and let pins matching at it was (UART_TX_PIN 6, UART_RX_PIN 8, UART_RTS_PIN 5, UART_CTS_PIN 7) I get all the logs of my app running on my NRF52!

Thank you for your quick support
