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
