Worked on the trezor/trezor-firmware repository to enhance the reliability of Python-based debugging sessions within the bridge transport layer. Addressed a persistent issue where debugging sessions could mismatch by ensuring the correct session ID was consistently used, leveraging the device’s debugSession value. This targeted bug fix improved the stability of developer workflows and reduced friction during device debugging and testing. The work involved in-depth debugging and Python development, focusing on transport layer communication between devices and the bridge. By refining session handling, the contribution supported more predictable and efficient testing processes for developers working with Python and device integration.
