scanf with NRF_LOG_INFO

[Bar]

Hello.

I have a project that use the NRF_LOG_INFO for printing messages, and it is work O.K.

Now I add a part that need also to get parameters from the terminal.

I can't make uart_init when the NRF_LOG_INFO is working because it has conflict with the uart in the sdk_config. 

So how can I use function like scanf when I to print the NRF_LOG_INFO on the some terminal?

Hello,

You can use NRF_UARTE1 if you don't need a command interface in the same terminal as the log messages, just remember to enable instance 1 in your sdk_config.h file. Another alternative is to use the built-in CLI support: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_nrf_log.html?cp=5_1_3_26_7#nrf_log_cli

Thanks Vidar. I just miss this replay. 

1. Is there any reference for example how to use NRF_UARTE1 for recieve & transmit messages?

2. Can I use NRF_UARTE1 for receiving and still use the NRF_LOG_INFO for output debage?

3. What do you mean by " don't need a command interface in the same terminal". I use the NRF_LOG_INFO. Is it a command interface ?

Hi,

1. You can find the driver documentation here if you want to use it directly: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/hardware_driver_uart.html?cp=5_1_2_0_19 

2. Yes, the logger module uses UARTE0 by default so there won't be any conflicts as long as you use UARTE1. 

3. You have to use different output pins if you have multiple UART instances so they can't be routed to the same "port". 

I'd recommend you to try the CLI example (examples\peripheral\cli) to see if it is something you could use.
