In-Place OTA DFU#
Component that provides in-place over-the-air (OTA) device firmware update (DFU) functionality. In this solution, the application flash area is used as a temporary storage for the update. This is a Low-Code component because additional security measures might be needed from user side for checking the correct security status. Our minimal solution can be seen in sl_bt_in_place_ota_dfu_security_status() function in sl_bt_in_place_ota_dfu.c file.
