|
|
* @brief DFU BLE SVC in bootloader. The DFU BLE SuperVisor Calls allow an application to execute
|
|
* functions in the installed bootloader.
|
|
*
|
|
* @details 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 @ref sd_softdevice_vector_table_base_set with the value
|
|
* present in @c NRF_UICR->NRFFW[0].
