Hi,

[quote userid="73655" url="~/f/nordic-q-a/37975/nrf52840-dongle-not-responding"]1. Is there a way to recover/revive this dongle?[/quote]

Yes. Plug the dongle in your computer, and press the RESET button. When the nRF52840 Dongle has entered the bootloader mode, LD2 pulses red. The Dongle is now ready for programming. See this page for more information.

[quote userid="73655" url="~/f/nordic-q-a/37975/nrf52840-dongle-not-responding"]2. What combination of hex files do I need to download in order to get basic BLE functionality?[/quote]

For basic BLE functionality, you will need the S140 SoftDevice and an application. Try one of the example applications in the ble_peripheral folder in the SDK for the pca10059. Note that the precompiled examples hex-files includes both application and SoftDevice. E.g. for the ble_app_hrs example, try the hex file ble_app_hrs_pca10059_s140.hex in the folder SDK15.1_folder\examples\ble_peripheral\ble_app_hrs\hex
