We develop modular, scalable, and maintainable ESP32 firmware using Espressif’s official ESP-IDF framework and FreeRTOS. Our engineers design firmware architecture based on the product’s processing, memory, connectivity, security, and real-time requirements.

Our services include application and bootloader development, FreeRTOS task management, inter-task communication, interrupt handling, memory and stack optimization, watchdog configuration, non-volatile storage, partition management, factory reset, device recovery, and migration from Arduino-based prototypes to production-ready ESP-IDF firmware.

We support hardware bring-up and firmware validation for custom ESP32 boards. Our engineers develop and integrate drivers for GPIO, ADC, DAC, PWM, UART, SPI, I²C, I²S, CAN, TWAI, USB, displays, cameras, audio components, sensors, GNSS modules, cellular modules, LoRa devices, motors, relays, external flash, PSRAM, EEPROM, and secure elements.

We also troubleshoot boot failures, pin configuration issues, power-related instability, timing problems, and hardware communication errors.

We develop quality wireless firmware for connected products based on ESP32. The Wi-Fi functions we provide include station and access-point modes, provisioning, captive portals, reconnection, HTTPS, MQTT, WebSockets, local discovery, and ESP-NOW.

For Bluetooth and BLE, we develop GATT clients and servers, custom services, advertising, scanning, secure pairing, bonding, BLE provisioning, mobile-app communication, data synchronization, and BLE Mesh solutions. For compatible ESP32-C and ESP32-H devices, we also support Matter, Thread, and Zigbee development.

We create safe systems for updating firmware over-the-air for the remote devices ESP32.

The services we provide include HTTPS firmware delivery, dual-partition OTA, signed firmware verification, automatic rollback, version handling, staged deployment, interrupted download recovery, fleet updating, integration with AWS, Azure or custom OTA.

Security is considered throughout the firmware architecture, depending on the firmware architecture.

For instance, available security implementations may vary among products since some devices have secure boot, flash encryption, encrypted NVS, signed firmware, secure provisioning, TLS communication, certificate-based authentication, anti-rollback feature, secure credential management, unique device identity, and production debugging.

We specialize in making firmware as energy-efficient as possible for battery-operated devices, including wearables, sensors, and remote monitoring systems.

This encompasses deep sleep modes, light sleep, wake-up sources, wireless transmission optimization, controlling sensor and peripheral power, dynamic power management, and current consumption profiling.

ESP32 devices work together with cloud platforms, backend systems, mobile applications, and dashboards as part of our expertise.

The technologies we work with include AWS IoT Core, Azure IoT Hub, MQTT, REST APIs, WebSockets, device shadows, telemetry, remote configuration, device control, alerts, and Flutter, Android, and iOS integration.

Our technical team looks into firmware failures, memory problems, watchdog resets, wireless connectivity issues, peripheral breakdowns, and electrical issues.

We conduct code inspections, core dump investigations, hardware-in-the-loop assessments, over-the-air evaluations, long-term reliability tests, fault-injection experiments, production test firmware writing, and remote diagnoses so that ESP32 devices are ready for safe commercial deployment.
