Hi Sigurd, I want to use a simple uart interface to send/receive information from a PC. I am using the nRF52 DK and SDK 12.2 and softdevice $132. at the moment I am pushing out information from the nRF52 using NRF_LOG_INFO(), and I want receive incomming data. Thanks

Which of the uart examples? ble_app_uart or uart? What device do you want to send information from? PC, µC or phone? What SDK version are you using?

Sigurd I know the question is solved, but can you give me any suggestion to receive information via uart to a nRF52? I was trying porting the uart example but I did not have luck

thanks

Thanks Sigurd! it is solved now. I changed the nRF_LOG_default_level to "info" and now it works pretty nice

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

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.

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 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

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

Or the console view in the Keil MDK5?
