UART module nRF52

[Arepa]

Hi all, I am trying to use the UART hardware module inside the nRF52 DK. I am very new programming with Nordic chips and C, my previous experience is programming Arduino and Atmel chips.

Can I use prinft() function to put out data from the uC programming in keil uvision5?

I tried use nRF_LOG_Info, but I think it works just for debugging not for the propose I want

sorry for the folk question

Thanks in advance

Hi, Arepa. When using the NRF_LOG_INFO, have you used the J-Link RTT Logger?

Or the console view in the Keil MDK5?

-Best Regards

Hi Mango. I have two devices one like central and other like peripheral, when the peripheral get the data from the central I want to send what I got to a PC using termite, but I dont know how to do this basic thing. I see the example codes they use nRF_LOG_Info but I think it is just for debugging not for transmit information

Do you know if there are something like printf() like arduino to put out data via serial? or how to receive serial incoming data

Hi,

You can use NRF_LOG_INFO() just like you use the printf(). E.g. NRF_LOG_INFO("Hello World\r\n");. Remember to enable the NRF_LOG in sdk_config.h. See this answer, and this answer on how to use the configuration wizard.

Hi Sigurd. I enabled NRF_LOG_ENABLED 1 and NRF_LOG_BACKEND_SERIAL_USES_UART 1 on sdk_config.h but I can't see anything on my terminal. I am using experimental_ble_blinky example on nRF52 DK my settings: s30.postimg.org/.../nrf52.png
