     2. After enabling this, the "**Number of Packets**" setting will become active, allowing you to reduce it. Try changing the number of packets to **5**. 
     3. Upload the firmware. Wait patiently. The upload speed is reported to be around 1 kB/s, so the process may take approximately 10 minutes to complete.
     4. If it still fails, reduce the value by one and retry the upload.
+3. **Prevent screen timeout during upload**: The iPhone's auto-lock feature is often set to 30 seconds or 1 minute by default. When this happens, the screen will go black, and the phone may go to sleep, potentially interrupting the Bluetooth firmware upload. To avoid this, temporarily set the auto-lock to "Never" during the upload process to ensure that the phone stays awake and the upload completes without interruption.
 
 *Note: Enabling "Packets Receipt Notification" is critical, as it unlocks the ability to modify the packet count. Reducing the packet size can significantly improve the upload stability and reduce the likelihood of failure.*
