Native SMS access for a desktop messaging companion

[claytondmalone]

I’m exploring a simple desktop companion for the native LP III messaging Tool.

The intended workflow would be:

1. Press Sync on the LP III to make SMS/MMS conversations readable through a private desktop interface.
2. Type a reply on the computer.
3. Transfer the draft back to the phone.
4. Open the native messaging interface with the recipient and message body prefilled, then manually press Send.

The upcoming File Manager and its API appear to provide a good path for transferring data between the Tool and a local desktop interface. The remaining questions are about integration with the native messaging Tool:

• Can an SDK Tool read incoming and sent SMS/MMS conversations from the native messaging database?
• Is there an existing or planned LightOS API for this, or would permissions such as READ_SMS / access to the Android SMS content provider be available?
• Would a Tool need to become the default SMS application?
• Can a Tool ask LightOS to open the native messaging interface with a recipient and message body prefilled?

Essentially an "upgrade" over the community work around of copying a text into the notes app, typing a response in the notes app from the desktop, and the copy/pasting that into messages.

Thanks for your time and for making the SDK available to the community. Any guidance would be appreciated.

@cmg-ops — thanks for the update, that's exactly the path I'm on (dashboard Developer Mode + External Tools → All Tools already set). USB keyboard methods (Win+N / Win+B) appear patched on my firmware, so I can't reach Android Settings to enable USB debugging.

Which Reddit guide / steps did you use to get into the Android layer after the keyboard loophole was closed? Happy to document whatever still works for others stuck in the same spot.
