There is a question in Test Setp about the buttonless DFU sample using the nRF52832 DK board.
(SDK is using 12.3.)

Question

Hi
I am currently testing Buttonless DFU using SDK 12.3, nRF52832 DK.
Example test was conducted first using the DK board, but as you can see in the picture, it will fail. I don't know why.
Is the method wrong?

Hi Aser, 
 If you instead click on the DFU button can you do a DFU update ? The app should detect that it's a buttonless application and perform the DFU buttonless automatically. 
 The buttonless application is quite simple. It waits for a write request to write to a flag in flash and then reset to the bootloader. 
 You can debug the buttonless application quite easily. You can check if enter_bootloader() is called inside on_ctrlpt_write() when there is a BLE_GATTS_EVT_RW_AUTHORIZE_REQUEST. 
 
 Please be aware that SDK v12.3 is pretty old. We changed the way we enter DFU bootloader (using GPREGRET instead of flash ) from SDK v13. The current SDK is v15.3
