Hi,

Are you able to resolve the issue that was mentioned?

I have followed the same document and my device is working properly.

At first, have you loaded the merged hex ?? (You should not just load the application file from IDE)

Merged hex file = Settings.hex + bootloader.hex + App.hex + softdevice.hex

This merged hex file is the complete package. You have to load this first using "nrf_connect for desktop"

If you have loaded this file, you will be able to load the application.zip package when there is an update available. You have to connect and load the .zip package...then device will do the auto restart if the application package is loaded completely and also you have to disconnect the device that is connected to mobile application or PC software. Now you have to scan from your mobile, then your device will advertise in the name which you have given.

Additional Info: If you want to debug your application code from IDE, you have to comment this function "ble_dfu_buttonless_async_svci_init();"

Thanks

Hi,

Please have a look on the following document. Section 5 is for buttonless DFU
