Training Covering Area

A comprehensive hands-on program designed for firmware developers, hardware engineers, and builders looking to transition from basic Arduino code to professional, robust, and secure ESP-IDF/C++ codebases.

Module 1: Architecture & Foundations

ESP32 hardware blocks & dual-core Xtensa microcontroller structure
Bootloader phase, custom partition tables, and memory mapping (IRAM/DRAM/Flash)
Setting up the ESP-IDF toolchain & project layout configurations
GPIOs, hardware timers, and basic peripheral drivers (ADC, DAC, PWM)

Module 2: FreeRTOS Core Primitives

Multitasking: Task priority, stack sizes, and core pinning (Core 0 vs Core 1)
Thread communication: Event loops, FreeRTOS queues, and ring buffers
Synchronization: Binary semaphores, counting semaphores, and mutexes
Dealing with priority inversion, watchdog timers, and task starvation

Module 3: Wi-Fi, BLE, and Cloud Protocols

Configuring station (STA) and access point (AP) modes with auto-reconnection
MQTT clients, HTTP REST clients, and secure WebSocket sockets
GATT Server design, BLE advertising packets, services, and characteristics
Securing data transit using SSL/TLS handshake client certificates

Module 4: Field Operations & Advanced Topics

Non-Volatile Storage (NVS) structure, custom FATFS filesystems, and partitions
Designing robust OTA update systems with custom backend server checking
Using core dumps, debuggers (OpenOCD), and firmware logging macros
Power profiling: Deep sleep current optimization, timer wakeups, and GPIO wakeups
