Level 2 · Intermediate Intermediate

Goal: move beyond the FreeRTOS core API — stream continuous data with stream and message buffers, allocate everything statically for deterministic memory, save power with tickless idle, understand the ESP-IDF's dual-core FreeRTOS, and structure real firmware with proven RTOS design patterns.

2. Static Allocation
3. Tickless Idle & Low Power
4. ESP-IDF FreeRTOS Specifics

6. Queue Sets & Advanced Queue Patterns
7. FreeRTOSConfig.h Deep Dive
8. Gatekeeper Tasks & Design Patterns
9. Watchdogs & Task Supervision
10. Project — Multi-Sensor Gateway
