Unable to pair nrf51 Dongle and the DK using nrf connect

[Klaus]

Whenever I hit pair to pair the nrf51 dongle with the DK, I keep receiving the error line: Authentication failed with status BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP

I read in another post that I have to delete some bonds, but how would I do that ? Is there more that I can do other than deleting bonds ?

Best,

@Klaus: Which firmware on the nRF51 are you testing with ? Please try to test with ble_app_proximity example.
