I Catch Up a Tesla BLE Library the Way I Run Agents 🚗

Description and use

An agent‑driven workflow cut Tesla BLE library updates from weeks to hours by adding automated tests with known‑good messages.

Problem

Updating a long‑quiet C++/Arduino Tesla BLE library was time‑consuming and risky because a single byte error could make the car ignore commands.

Outcome

The agent‑driven workflow cut the update time from weeks to hours, providing reliable automated tests that catch protocol errors immediately.

Workflow

• Plan the update and gather independent takes to avoid single‑point bias.
• Add a small host test suite with known‑good Tesla BLE messages to serve as automated checks.
• Configure an agent to run the tests and apply changes to the library.
• Let the agent execute the busywork; on failure, fix the issue and let it continue.
• Repeat until all tests pass and the library is fully updated.
• Verify the updated library against a real Tesla to ensure no regressions.

Evidence

Same day: what used to feel like weeks became hours.
