NRF dongle PCA10031 disconnects after 24 seconds while running ble_app_blinky

I I'm running the ble_app_blinky example under pca10028 on the nrf dongle pca10031 using sdk11. The dongle disconnects after 24 seconds. Can anyone point to me what is the problem causing this disconnection?

Uhm, what if I want to create a custom ble service and characteristic on the dongle. Through the tutorial characteristic master file. It only has pca10028 and pca10040. How do I create one for pca10031
