ANT OTA Updater tool connection failed

Hi,

I am trying to implement the DFU ANT Bootlaoader on my PCA100040 board. I have uploaded the softdevice S212 and the bootloader with nRFgo Studio. I have an ANT dongle connected to my PC. But the OTA Updater (v1.4.0) is not able to connect to my board.

I get "Connection to device failed: Unable to find specified device. Check Connection Settings and try again." when I click on Connect to Device.

I have all the filters unchecked in connection settings and chooese nRF52 as hardware platform.

P.S: I uploaded OTA Tester to my board from nRFgo Studio and checked for the boradcast data using AntwareII. It works well.
