Great! Now you need to adjust the RAM settings. In Keil go to "Options for Target.." to change the RAM start and size. Under "Read/Write Memory Areas" set "Start" to 0x20001fe8 and "Size" to 0xe018.

I actually got it to work on the COM9 using PuTTY. However, the app still crashes at power_manage with the following TTY output: SDH:INFO:sd_ble_enable: RAM START at 0x20002128 SDH:WARNING:sd_ble_enable: app_ram_base should be adjusted to 0x20001fe8 SDH:WARNING:ram size should be adjusted to 0xe018 APP:INFO:Heart rate collector example APP_ERROR:ERROR:Fatal

Then you also need to enable the RTT logging. Make sure you have NRF_LOG_BACKEND_SERIAL_USES_RTT 1 in sdk_config.h. Remember to enable the NRF_LOG in sdk_config.h. See this answer, and this answer on how to use the configuration wizard.

I'm using sdk 12.1.0 and ble heart rate service plain. I think I should be able to use the SEGGER usb connection uart as it shows in windows as COM9. Börje

NRF_LOG_ENABLED=1 directs the NRF_LOG_xxx statements to the UART, so you need to connect a USB to Serial adaptor to whichever pins are defined to be the UART for your board.

What SDK version is this? Also, what examples in the SDK are you testing? Where are you setting NRF_LOG_ENABLED=1? in sdk_config.h or as a define?
