Contributions summary:Timothy primarily contributed to the Bluetooth Host stack within the Zephyr RTOS, focusing on bug fixes, code cleanup, and unit test additions. Their work involved correcting spelling mistakes, removing redundant code causing build errors, and implementing unit tests for specific Bluetooth functions. Additionally, they addressed a critical issue related to deferred work during Bluetooth disconnect operations and fixed compiler warnings by null-terminating RPMsg endpoint names. They also removed the experimental flag for LE Connection Subrating.
