- 2:08Zephyr's "OS personalities" • Zephyr's own native API . Most importantly, POSIX
- 10:25Summary: • Zephyr-adhoc API • Low-level and error-prone • Collback-based, not compatible with userspace mode
- 17:35Packet sockets allow to perform L2 communication using Sockets API Currently, only Ethernet is supported • CAN sockets are implemented, roughly compatible with Linux (work undergoing to polish the rough edges).
- 18:15Elaborating Sockets API Mostly based on case studies with porting POSIX software • Example: OPC UA protocol implementation - apen62541 lib Working on Zephyr port
- 22:23Future work • Better integration between POSIX and Socket subsystems • Socket-based protocollibs for HTTP WebSocket • More socket features/options • New TCP implementation
