Detailed Description

DFU BLE SVC in bootloader. The DFU BLE SuperVisor Calls allow an application to execute functions in the installed bootloader.

This module implements handling of SuperVisor Calls in the bootloader. SuperVisor Calls allow for an application to execute calls into the bootloader. Currently, it is possible to exchange bonding information (like keys) from the application to a bootloader supporting DFU OTA using BLE, so the update process can be done through an already existing bond.

Note

The application must make sure that all SuperVisor Calls (SVC) are forwarded to the bootloader to ensure correct behavior. Forwarding of SVCs to the bootloader is done using the SoftDevice SVC sd_softdevice_vector_table_base_set with the value present in NRF_UICR->BOOTLOADERADDR.
