ble_app_uart is not receiving nor on app nor on PUTTY/termite terminals.

[beginner_bus]

I am a beginner trying to implement ble_app_uart example from SDK 15,  example compiles with no problem, advertizes. LED 1 blinks when advertizing, and turns ON when connecting through PROXY application (couldn't find nRF UART in app store), when trying to connect using nRF toolbox it quits. I don't receive any data i want to send, not working with PUTTY and Termite terminals as well. I expect "uart started" message but it is empty. What might be the problem? I am using nRF52840 DK and arm keil v5.

Hi

Have you configured the terminal with the correct COM port that your device is connected to on the computer (can be found in the device manager) and the correct baud rate (115200 by default)? "UART started" should be printed to the terminal. Are you able to find the device when scanning for it using the nRFConnect app? LED1 on the DK should be blinking when it is advertising, please check that it is.

Best regards,

Simon
