Best Settings for Christersson SendFile on Sony Ericsson Models
Note: Christersson SendFile is a third-party utility for sending files via Bluetooth/OBEX to older Sony Ericsson phones. Below are recommended settings and steps to maximize compatibility and transfer reliability across typical Sony Ericsson feature-phone and early smartphone models.
1. App version & phone compatibility
- Use the latest compatible SendFile build available for your PC or device; older Sony Ericsson models (pre-2010) may require legacy builds.
- Confirm phone Bluetooth OBEX support (most Sony Ericsson models support OBEX Object Push and File Transfer profiles).
2. Bluetooth pairing & connection
- Pair first: Pair the phone and the sending device in the phone’s Bluetooth menu before attempting SendFile transfers.
- Visibility: Set the phone to visible/discoverable during the initial pairing.
- Trusted device: Mark the sending device as trusted/paired on the phone to avoid repeated prompts.
3. Transfer profile and port
- Use OBEX Object Push (OPP) for single-file sends and OBEX File Transfer (FTP) for browsing folders (if supported).
- If SendFile offers profile selection, choose OPP for higher compatibility with older models.
4. File size & format
- Keep individual files under 1–2 MB for older phones to avoid timeouts or memory limits; split larger files if needed.
- Use compatible formats: For multimedia, prefer formats known to be supported by the phone (e.g., JPEG for images, 3GP/AMR for video/audio depending on model).
5. Transfer retries & timeouts
- Increase timeout or retry settings in SendFile if transfers fail frequently, especially with slow Bluetooth stacks.
- Enable automatic retries if available.
6. Connection stability
- Minimize distance and interference: Keep devices within 1–2 meters, away from Wi‑Fi routers or other Bluetooth devices.
- Disable power saving on the sending device during transfers to prevent the Bluetooth radio from sleeping.
7. Folder target on phone
- Choose the correct destination folder: Some Sony Ericsson phones require files to go to specific folders (e.g., Images, Sounds, Videos) to appear in galleries or media players.
- If SendFile allows specifying the target folder or MIME type, match the phone’s expected folder structure.
8. Security prompts & acceptance
- Be ready to accept prompts on the phone; enable “accept automatically from trusted devices” if comfortable with that setting.
- For repeated transfers, set the phone to always accept from this device to avoid manual confirmation.
9. Driver and PC settings (if sending from computer)
- Install the proper Bluetooth stack/drivers: Use the Microsoft stack or vendor stack compatible with your Bluetooth adapter.
- Run SendFile with appropriate privileges if it needs access to Bluetooth hardware (Windows: run as administrator if problems occur).
10. Troubleshooting common issues
- Transfer stalls: Cancel and retry after toggling Bluetooth on both devices.
- Permissions errors: Remove pairing and re-pair the devices, then retry.
- File not visible on phone: Verify correct folder and supported format; try sending a small JPEG to confirm.
If you tell me the exact Sony Ericsson model and whether you’re sending from a PC, Android phone, or other device, I can give model-specific recommended formats, folder targets, and exact timeout/transfer settings.
