Simulate real-world field connectivity conditions to verify that your firmware's edge ring buffer protects against telemetry data loss.

Edge Buffer Protection Rule:

When network connectivity drops, telemetry packets are automatically spooled into the simulated LittleFS non-volatile ring buffer. As soon as connectivity is restored, Telematric replays the buffered queue chronologically with zero data loss.

Workspace telemetry & optional virtual OTA

Start standalone without credentials. To send synthetic telemetry to Telematric, enter a development API key with devices:read and telemetry:write, your workspace UUID and a registered development device UUID. Live requests consume your workspace allowance.

OTA is a separate opt-in: add firmware:read and an existing supported ESP32 target’s OTA token. Check deployments, verify downloaded bytes and simulate reboot, healthy completion, interruption or rollback. No firmware binary executes and no physical device is flashed.

Project metadata and bounded telemetry queues are saved in this browser; secrets are not. Reload and scenario imports never connect automatically. Your own backend or OTA tooling can be used independently.

1. What is Happening Behind the Scenes

The Telematric Pre-Silicon Simulator is an embedded digital twin studio that emulates the behavior of physical IoT silicon in real time before PCB fabrication:

Time-Series Physics Engine
Executes numerical physics algorithms every interval tick (default 1000ms). Simulates barometric atmospheric drift, humidity fluctuations, battery LiFePO4 cell discharge curves, and 3-axis motion kinematics.
RTOS Kernel Emulation
Models the preemption, priority, and thread state transitions of Eclipse ThreadX (100Hz SysTick) and FreeRTOS. Mimics real hardware timer interrupts and thread sleeping routines.
Network Chaos & Edge Buffer
Simulates field connectivity disruptions (packet loss, RF jitter, total carrier drops). Verifies whether your firmware correctly spools dropped readings into local LittleFS storage and replays them on reconnect.
Live Telematric Ingestion
Generates production ISO 8601 UTC JSON payloads. In live mode, posts authenticated HTTP telemetry directly to your Telematric organization (/v1/telemetry/reading) to trigger real alert rules.
2. What the Simulator Offers
  • Zero-Hardware Verification: Test entire IoT dashboards, alert webhooks, and billing meters before spending thousands of dollars manufacturing custom hardware.
  • Dynamic 2-Board Virtual Workbench: Dynamically swaps the virtual hardware workbench between the ESP32-DevKitC V4 and the authentic MXChip AZ3166 IoT DevKit (featuring a live 128x64 VGM128064 OLED screen, ST sensor cluster, user buttons, and 14 gold edge fingers) based on the active profile.
  • Interactive Pin Testing & Digital Multimeter: Select a virtual pin to inspect illustrative voltage values, toggle simulated logic levels and view pulse animations with simulated serial logs. No electrical or interrupt verification is performed.
  • Pre-Silicon Memory Profiler: Mathematically validates Flash partition layout (Dual A/B OTA rollback slots) and RAM heap headroom (mbedTLS handshake buffers) against actual MCU silicon specs (e.g., STM32F412RG 1MB/256KB or ESP32 4MB/320KB).
  • Interactive Fault Injection Matrix: Dynamically inject I2C bus lockup (0x43 timeout), mechanical drop/shock events, pressure surges, and Wi-Fi disconnects to test firmware panic recovery.
  • Live In-Browser Code Editor & Hot-Reload: Edit custom C++ firmware code directly in the browser and click Run Code to update the live simulation outcome immediately.
  • Production Firmware Export: 1-click download of ready-to-compile C++ source code (az3166_threadx_main.cpp or main.cpp).
3. What to Account for on Physical Silicon

While the digital twin provides illustrative device behavior and selected telemetry contracts, physical hardware introduces real-world electrical and environmental factors that engineers must account for:

Domain Simulator Digital Twin Physical Hardware Reality Engineering Action Needed
Wi-Fi & RF Network Auto-connected virtual network Physical walls, 2.4GHz interference, router distance Configure real SSID/Password in cloud_config.h; ensure 2.4GHz band is enabled.
Sensor Accuracy Physics-derived mathematical curves MEMS manufacturing tolerance (±0.5°C, ±1.5% RH) Apply zero-point calibration offsets if laboratory precision is required.
Thermal Soak Calculated ambient dissipation MCU core & Wi-Fi chip warm the PCB enclosure Duty-cycle sensor reads; subtract self-heating factor (~1.5°C when Wi-Fi is active).
Power Delivery Continuous simulated power Wi-Fi transmit current spikes (~250mA peak) Ensure USB cable or power supply provides ≥500mA without dipping below 2.7V.
4. Flashing to Physical Hardware (MXChip AZ3166 & ESP32)

A. Flashing the MXChip AZ3166 (Eclipse ThreadX):

  1. Connect the AZ3166 board to your Mac or PC using a micro-USB cable.
  2. The board automatically mounts as a virtual USB drive named /Volumes/AZ3166 (macOS) or D:\ (Windows).
  3. In your terminal, navigate to the samplex repository and compile:
    ./scripts/build.sh telemetry
  4. Deploy by copying the compiled binary to the board:
    ./scripts/deploy.sh /Volumes/AZ3166
  5. The board will reboot and immediately begin executing Eclipse ThreadX and streaming telemetry.

B. Flashing ESP32 Microcontrollers:

  1. Click Download .cpp in the Firmware Editor tab to download main.cpp.
  2. Open with Arduino IDE or PlatformIO. Install ArduinoJson library.
  3. Compile and upload via USB serial port (/dev/ttyUSB0).
5. In-Browser Code & Hot-Reload Loop

You can customize the firmware logic without any local compilers installed:

  1. Navigate to Tab 4: Wokwi & C++ Bridge.
  2. Click inside the Target Firmware Editor box to type or paste custom code.
  3. Edit device constants such as TELEMETRY_INTERVAL_SEC or adjust sensor alarm thresholds.
  4. Click Run Code in Simulator: The studio reads supported parameters from your code text and triggers an updated simulation cycle on the waveform canvas and serial monitor!
6. Pin Testing & Multimeter Probing Procedure

Explore illustrative pin states in the virtual workbench. No physical pins are measured or driven:

  1. Attach Multimeter Probe: In Tab 4: Wokwi & C++ Bridge, click any physical pin on the ESP32 (e.g., GPIO 15, GPIO 2, EN) or gold edge finger on the AZ3166 (e.g., PA4, ADC1_IN0). The Multimeter HUD connects instantly.
  2. Measure Live Voltages (Read Volts): Click Read Volts to capture an illustrative voltage value with synthetic jitter (±8mV), logged to the simulated serial monitor. These values are not electrical measurements.
  3. Drive Logic Levels (Pull LOW / Pull HIGH): Click Pull LOW (GND) to drive the pin to 0.00V GND. If probing GPIO 15, this closes the safety trip switch and triggers an immediate digital twin alarm. If probing EN, it reboots the microcontroller. Click Pull HIGH (3.3V) to inject 3.3V and restore nominal state.
  4. Signal Generator Pulse Injection: Click Inject Pulse to strobe a 100ms logic clock pulse on the selected virtual pin. This does not execute MCU instructions or verify hardware interrupts.
