BLE + Nordic nFR52 DK.

Hello, 

I'm new in Garmin and I'd like to connect a device using BLE. 

I read documentation about nRF52 DK 

I bought this device

I found this topic https://forums.garmin.com/developer/connect-iq/f/discussion/194248/does-the-3-1-x-sdk-connect-the-simulator-to-a-nrf52840-for-ble-or-does-it-only-work-with-the-nrf52-dk?ReplySortBy=CreatedDate&ReplySortOrder=Ascending where I found a file connectivity_1.0.0_usb_with_s132_5.1.0.hex (documentation has a lot of dead links, so I found this HEX on the forum)

I flashed this file into my nRF52 device. Than I configure the simulator with COM port. It did not show any error, so I suppose it works.  

Now I'm trying to run NordicThingy52 example and always get "device: 0/0". "Start Scanning" from menu doesn't help. Of course I have my BLE device switched on and my phone and even nRF52 (with "Bluetooth low energy" application) can see it. 

What do I wrong? am I missing may be something?

Thanks
