I will debug and fix esp32 mqtt wifi ble firmware issues
Full Stack Developer React Native TypeScript AI IoT Integration
About this Gig
Is your ESP32 project not working as expected?
WiFi keeps disconnecting? MQTT is not publishing? BLE is not connecting? Getting crashes, watchdog resets, compilation errors, or unstable behavior?
I will debug, fix, and improve your existing ESP32 firmware.
I can help with:
WiFi connection and reconnection issues
MQTT publish/subscribe problems
BLE communication and advertising
HTTP / REST API integration
Compilation and library errors
Watchdog resets, crashes, and timing issues
JSON parsing and data handling
FreeRTOS tasks and firmware stability
Existing code debugging and optimization
What you receive: corrected source code, the implemented fix, and a clear explanation of what was changed.
To start, please send your ESP32 model, source code, logs/errors, wiring or module information if relevant, and the expected behavior.
Important: physical hardware testing is not included unless agreed beforehand. I can work from your code, logs, datasheets, and documentation.
Please message me before ordering so I can confirm the scope and recommend the right package.

FAQ
Can you fix my ESP32 project without having my hardware?
Yes. For many firmware issues, I can work from your source code, logs, board model, datasheets, wiring information, and expected behavior. If physical hardware testing is essential, please contact me first so we can confirm the scope.
What do you need from me before starting?
Please send your ESP32 model, source code, error messages or serial logs, relevant libraries, wiring/module information, and a short explanation of what should happen versus what is happening now.
What is included in the Basic package?
The Basic package covers one clearly defined issue in an existing ESP32 firmware project, such as an MQTT, WiFi, BLE, compilation, JSON, or stability problem.
Can you add MQTT, WiFi, BLE, or API communication to my project?
Yes. I can implement or fix ESP32 connectivity using MQTT, WiFi, BLE, HTTP/REST APIs, and related communication logic. Message me before ordering so I can recommend the correct package.
Do you provide the source code?
Yes. Source code is included with every package. I will also explain the main changes made to your firmware.
Can you work with sensors or modules I use in my project?
Yes, depending on the module and available documentation. Send me the exact model or datasheet first. I can implement drivers and integration logic even if I do not physically own the same hardware.
Can you build a complete ESP32 IoT project from scratch?
Yes, but a complete project is usually outside the scope of the Basic package. Send me your requirements first and I can provide the appropriate package or a custom offer.
What if you cannot reproduce my bug without the physical device?
I will analyze the code, logs, timing, communication flow, and documentation and provide the best software-side diagnosis possible. If physical validation is required, I will tell you clearly before making unsupported claims.
