Dear Peter,

Sorry about the delay to reply you, holidays. So I still have the problem, I tested with your suggestions: NRF_LOG_BACKEND_SERIAL_USES_RTT = 1 NRF_LOG_BACKEND_SERIAL_USES_UART=0 The TTY host software on an USB only

// using ble_app_uart_c for example main() { timer_init(); uart_init(): .... printf("\r\nHello world - printf()"); NRF_LOG_INFO("\r\nHello world - log()"); .... }

I got the following (only) on the TTY: Hello world - printf()

I expected to don't have the **...printf()..." on the RTT. Perhaps a retarget() default initialization?

Any idea?

Comment: I got the same output with: NRF_LOG_BACKEND_SERIAL_USES_RTT = 0 NRF_LOG_BACKEND_SERIAL_USES_UART=0

Thanks,

Why would you set NRF_LOG_BACKEND_SERIAL_USES_RTT = 0? It should be 1. And NRF_LOG_BACKEND_SERIAL_USES_UART=0. Actually the ble_app_uart example should work like that out of the box. NRF_LOG_INFO() should appear on RTT and printf should appear on UART.

Peter, I re-do the test using SDK 13.0.7ca7556 with the ble_peripheral\pca10056_s140

the only modification I did was: NRF_LOG_BACKEND_SERIAL_USES_RTT=0 and adding in the main(): printf("Hello word -printf"); NRF_LOG_RAW_INFO("Hello word -NRF_LOG");

Results: PuTTY USB/RS232: Hello word - printf PuTTY UART: Hello word - printf

(the Hello word -NRF_LOG didn't output)

I expected to have only the ouput on PuTTY UART and nothing on the PuTTY USB/VCP

Sorry about my previous text mistake

Strange. Seems to be working fine here. Have you made any other changes to the project?

Yes, I tried your setting and I got the following:

NRF_LOG_INFO("Hello word NRF LOG") => nothing on the both two PuTTY (USB/VCP & UART)

printf("Hello word printf") => I got the "Hello word printf" on both the two PuTTY (USB/VCP & UART)

I excepted to have: "Hello word NRF LOG" on PuTTY USB/VCP "Hello word printf" on PuTTY UART

Thanks for you fast reply Petter

John

NRF_LOG_ENABLED=1, NRF_LOG_BACKEND_SERIAL_USES_UART=0, NRF_LOG_BACKEND_SERIAL_USES_RTT=1 ?
