Sobre este Serviço
Headline: Expert ESP32 BLE Firmware Development for Robust IoT Communication
Are you building an IoT device that requires reliable Bluetooth Low Energy (BLE) connectivity?
I specialize in writing high-performance, secure Embedded C++ firmware on the ESP32 platform. I deliver commercial-grade BLE Client and Server solutions that ensure seamless, bidirectional communication and fast real-time data exchange.
What I Offer:
- Custom BLE Architecture: Implement BLE Client (Scanner/Receiver) and BLE Server (Advertiser/Notifier) roles.
- GATT Services: Define custom GATT Services and Characteristics to match your application's data structure.
- Production Ready: Clean, reliable code optimized for low-power consumption and multi-tasking using FreeRTOS.
- Integration: Code ready to integrate with your mobile app or other BLE peripherals.
Skills & Deliverables:
- ESP32,
- Bluetooth Low Energy,
- Embedded C
- C++
- Firmware Programming.
- Cloud Automation (AWS IoT, Google Home, Home Assistant)
- Wifi
- Embedded Linux & MCU Firmware
- OTA, Secure Boot, Industrial Automation
LET'S BUILD YOUR CONNECTED DEVICE.

Perguntas frequentes
Which ESP32 boards do you support?
I primarily use standard ESP32 and ESP32-S3 modules, but the firmware can be adapted to any specific ESP32 variant or STM32 with BLE support.
What is a GATT Characteristic?
A GATT Characteristic is how data is structured and exchanged over Bluetooth Low Energy. It's essential for bidirectional IoT communication.
Does this Gig include the mobile app code?
No. This Gig is for the ESP32 firmware only. I can, however, provide consultation on integrating the BLE data correctly into your mobile app.
How do you ensure firmware is scalable and maintainable?
By using layered architecture, reusable drivers, configurable HALs, RTOS-based task separation, and detailed documentation. This enables smooth updates, easier debugging, and long-term scalability.
Can you help scale a prototype into a production-grade system?
Yes. I support the full lifecycle from prototype → MVP → field trials → production. I optimize BOM, reduce firmware footprint, improve reliability, enable OTA updates, and ensure cloud + device stability for mass deployment.
