# Usage

- The OTA Reset Manager is a basic application which is is stored at BlueNRG-1 FLASH base (0x10040000) and it allows to transfer of control towards the new upgraded application every time we reset.
- The new application has to add the OTA service and related characteristics defined on files OTA_btl.c.
- At device reset, the reset manager will take care of jumping to the location of the last image that was successfully loaded by the OTA bootloader.

NOTEs

- Before downloading the OTA Reset Manager perform a device Mass Erase of the selected BlueNRG-1 device (use IAR, Project, Download, Erase Memory). Then, open the IAR project related to a Lower Application with OTA Service and download it on the selected device. At this stage, the BlueNRG-1 device is ready for performing OTA upgrades.
- Refer to BLE_Chat and SensorDemo workspaces IAR projects for related OTA examples (Lower and Higher Applications with OTA service workspaces).
