We are currently using the 52840 DK board to do OTA DFU with BLE and the nrfutil.
We connect the DK board to a linux machine and run the nrfutil with the dfu ble options and it loads firmware into the DK board.
Then it DFU's over the air, the application firmware into remote nrf52840 chips.
Is there firmware available that we can load into the nrf52840 dongle to replace the DK board ?
Or are there instructions somewhere on how to do this?
Hi,
The dongle can be used with nrfutil, but first, you need to load the connectivity FW onto the dongle. This is easiest done by launching the Bluetooth Low Energy app in nRF connect for desktop (link) and click "yes" when it asks you to program the device.
The dongle is ready to be used with nrfutil after the FW is loaded.
