Developed a CoAP Request Options Customization API for the nrfconnect/sdk-nrf repository, enabling users to define and retrieve custom CoAP request options for the nrf_cloud_coap_transport module. This work focused on enhancing flexibility in routing and data handling by allowing overrides of default Memfault diagnostic data routing, addressing the CLOUDMCU-37 use case. The implementation involved C programming and leveraged expertise in API development, embedded systems, and network programming. The API, nrf_cloud_coap_get_user_options, was introduced and documented to support user-specified options, providing a foundation for more adaptable cloud communication scenarios. No critical bugs were reported during this period.
