nrf52840 dongle original firmware

[Manuel_Encore]

Hello everyone,

I've been messing around with a nrf52840 dongle we've got in our company and I wanted to restore it to the original state, but I cannot find the hex file anywhere (the firmware which works perfectly with the nrf connect windows app). Where could I get it?

Best regards,

Manuel

Hi,

Do you mean the connectivity firmware to make the dongle work with the BLE app inside nRF Connect for Desktop? If so, try pressing the RESET button on the dongle then launch the BLE app and a prompt will come up asking if you want to program the dongle.

Many thanks, that solved the problem, I was looking for the hex for programming with the app, but this was even better
