Experimental: Buttonless DFU Service
This information applies to the following SoftDevices: S130, S132, S332

This module implements the Buttonless DFU Service. It has one control point which may be used to enter bootloader mode. When notifications are enabled, and the user writes 0x01 to the control point, the device restarts in bootloader mode.

Note
The application must propagate BLE stack events to the Buttonless DFU Service module by calling ble_dfu_on_ble_evt() from the SoftDevice Event Handler callback.
