Hi Martin, It is working. The problem was with jumper connected to GPIO rather than 32Khz . Thank you for the support.

We have nRF51822 development dongle, nRF51822 DK with PCB antenna and SMA connector module. But not the motherboard. So there is no any led.

I am using SDK 9.0.0 and softdevice is S110 8.0.0.

Do you use on of Nordic's kits? Are some of the LEDs blinking after you have flashed the Softdevice and your application? What SDK and Softdevice version are you using?

I gone through that document and flashed softdevice in dongle. But I am having a DK with on-chip antenna and programmed softdevice to DK and then flashed heartrate application using keil IDE. Then tried to connect with my mobile, but the device is not getting detected. I am using JLink programmer to flash the code to DK board.

Maybe you have forgotten to flash a Softdevice to your dongle? I should probably have pointed you to this tutorial earlier instead of the previous one: Setting up an example project on the nRF51 DK.

This is a more in depth description of how to get a bluetooth example working.

Hello Martin, Thanks for the link. Now I am able to connect to the dongle using nRF Toolbox application on my mobile. Now I programmed the heart rate application on DK board but the device is not getting detected. Am I missing anything?

Have you seen this tutorial: Setting up device firmware update(DFU) on the nRF51 DK?

It is really a tutorial on Direct Firmware Upgrade, but it also shows how to open or create a project.
