Flashing nRF52833 over Bluetooth using the nRF52840 (PCA10059)

[nrfquestion]

Is it possible flash a nRF52833 over Bluetooth using the nRF52840 (PCA10059)? Or initiate DFU mode over Bluetooth using the dongle or a PC?

How could this be achieved?

Hi, 

Since nRF52840 (PCA10059) doesn't have the on-board debugger (OBD), it cannot program the chip. You need a DK which have the on-board debugger (OBD) such as nRF52DK, nRF52840DK, nRF52833DK. 

If you want to update via BLE DFU, it still needs to program bootloader to nRF52833 at first.

Thank you

What would be the process once using a DK?

Hi, 

Have a look at Debug output section of the DK user guide. Please make sure to provide the power both for the DK and chip board.
