I need to develop a beacon application with the OTA DFU capabilities (Buttonless). I have the NRF51-DK.
As a starting point, I tried the bootloader example located in the \nRF5_SDK_12.3.0_d7731ad\examples\dfu directory to do a secure DFU( with button). I followed the instructions up to step D found in this Ble tutorial.
I am using the ble_app_beacon example with S130 soft device.
Once i do DFU, the dev kit stops advertising altogether. I am able to put the dev kit in to DFU mode again by pressing button 4 during power up. Why doesn't the dev kit advertise?
I assume that after I do the dfu, the dev kit should act as a non-connectable beacon unless I put it in DFU mode by pressing button 4 at power up. Am I correct?
