https://devzone.nordicsemi.com/f/nordic-q-a/11792/nrf52-dfu-bleHi, im trying to update the firmware of a nrf52 using dfu ble. For example, have a blinky example running and switch to a blinky2. Can anyone know if this is possible?en-USTelligent Community 13Tue, 09 Feb 2016 08:50:34 GMThttps://devzone.nordicsemi.com/thread/44583?ContentTypeID=1Tue, 09 Feb 2016 08:50:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4a8eea6f-56c4-4b90-9106-1b08d6e4bf6cVidar Berg<p>Yes, but first you need to enter Bootloader DFU mode. Since the blinky example doesn&#39;t have any ble functionality this has to be done with a physical button or similar. Button 4 is the default button for this on the 52 DK kit. Just hold this button while doing a system reset to enter DFU mode, and then you can start uploading the new FW.</p><div style="clear:both;"></div>
