Is there a way to do DFU without interaction on server

[Renix]

The server has no I/O, so no way to press a button.

Can an attribute cause the BLE to set a bit in Flash, so at the next power up, it will read that bit and know to execute the boot loader for DFU?

Any help appreciated

Hi,

Yes, you can use Buttonless DFU. You can find the Buttonless DFU example in the folder

SDK_InstallFolder>\examples\ble_peripheral\experimental_ble_app_buttonless_dfu
