Project Summary

Droid Technologies developed a stable OTA system and Wi‑Fi firmware for an ESP8266-based module to connect securely to the client's backend. The firmware was implemented in C++ with TLS and MQTT support; the delivered product met project goals and is now being mass-produced. The client praised the code quality and communication.

Key Challenges

  • Develop firmware for ESP8266 to make circuits smart and communicate with backend servers
  • The client lacked an embedded department and required external support
  • Deliver a stable module that securely connects over TLS, supports OTA updates, and allows pin control via MQTT

Project Deliverables

  • OTA update system
  • Wi-Fi firmware for ESP8266 compatible with the client's backend
  • Firmware with TLS communication and MQTT-controlled pin management

Project Solution

The vendor developed C++ firmware for an ESP8266 module that securely connects to the client's backend, implements TLS communication, supports MQTT-based pin control, and includes an over-the-air update system. The delivered firmware functioned as required and was subsequently mass-produced. The engagement was executed by one engineer and managed via Jira.

Project Outcome

  • The code was high-quality
  • The product met project goals and is being mass-produced
