Assistance with obtaining the legacy Open AT SDK / Application Framework for the Wavecom Q2686 modem

Looking for a specialist who can help find and obtain a working installation package for the legacy SDK for the old Wavecom / Sierra Wireless Q2686 Wireless CPU modem.

Task Objective:
To obtain the installation package (installer or zip archive) for Open AT SDK or Open AT Application Framework, necessary for developing/building applications for Q2686. If the package is not available for direct download, a guaranteed working method to download it is needed, which I can use without a corporate Sierra Wireless / Semtech account.

What is needed:

• Find an official or archived source for Open AT SDK / Open AT Application Framework.

• Priority versions:

  • Open AT SDK 4.21, if available;

  • or Open AT Application Framework 2.5X / 2.52;

  • Developer Studio compatible with Open AT Framework 2.5X.

• Verify that the found SDK/Framework is suitable for Wavecom/Sierra Wireless Q2686.

• Provide either the installer file (archive) itself or detailed instructions on how to access it without a corporate account (e.g., through an official request, archived copies, etc.).

• Specify what additional components are needed: firmware, download tools, Windows USB drivers, and where to obtain them in compatible versions.

Final deliverables:

1. A working installation package (or guaranteed working source) for Open AT SDK / Application Framework for Q2686.

2. Confirmation of which version is suitable: SDK 4.21 or Open AT Application Framework 2.5X / 2.52.

3. A brief guide on obtaining/installing and verifying the version.

4. A list of necessary additional files: firmware, download tools, drivers (with links or attachments).
