Worked on the matteocrippa/firmware repository to enhance device provisioning reliability across ESP32 variants by addressing MAC address retrieval for ESP32C6 devices supporting IEEE 802.15.4. Focused on embedded systems and device driver development using C++, the work involved refactoring the getMacAddr function to utilize esp_base_mac_addr_get for 802.15.4-capable devices, with a fallback to esp_efuse_mac_get_default for legacy hardware. This approach ensured consistent MAC-48 format compatibility and reduced provisioning failures across networks. The update improved code maintainability and robustness, directly supporting interoperability for newer ESP32 variants while maintaining backward compatibility for existing devices within the firmware codebase.
