RE: J-Link can't connect to nRF51 Dongle

Thanks, Martin! The suggestions in the thread you posted worked. Specifically, I plugged the Dongle in while holding down its only button. It then appeared in Windows Explorer as a storage drive called "BOOTLOADER". I dragged and dropped the file linked in the post onto it and then cycled power on it. I could then update its firmware using Jlink.exe. I then power cycled it again and Wireshark is now working with it.
