 This application demonstrates the procedure to update the SiWx91x module's firmware by receiving a firmware file from a remote device via BLE. The application has the provision to upgrade both TA and M4 firmwares. 
 The update process works as follows:
    - The SiWx91x module is configured as an advertiser, and an OTA GATT database acts as a GATT server.
-   - The GUI/EFR Connect App is configured as a BLE central and GATT Client.
-   - When the BLE connection is established between the SiWx91x device, you can browse either M4 or TA file from the GUI/EFR Connect App.
-   - The GUI/EFR Connect App sends the selected firmware, either M4 firmware or TA firmware file.
