I will develop esp32 esp idf firmware mqtt ble wifi iot cloud API sensor integration
About this Gig
Using ESP32 and ESP-IDF, I can develop Wi-Fi connectivity, BLE GATT services, MQTT or HTTP/HTTPS messaging, REST API integration, sensor drivers, GPIO, I2C, SPI, UART, PWM, ADC, and FreeRTOS tasks. I can help connect your device to a cloud endpoint, structure telemetry and command messages, handle reconnects, and make communication faults easier to diagnose.
The workflow is simple: define expected behavior and interfaces, implement the agreed modules, then verify specified scenarios and document the build. Depending on your hardware, scope can include Wi-Fi provisioning, TLS communication, watchdog handling, logging, low-power behavior, and OTA-ready architecture.
Before ordering, send your ESP32 model, ESP-IDF version, peripheral list, protocol or API details, and expected behavior. I will confirm dependencies, test conditions, and deliverables first.
Delivery may include source code, configuration notes, build instructions, and a concise test summary. Real-hardware testing requires board access or a reproducible setup. Mobile apps, cloud infrastructure, and certification are excluded unless agreed in advance.
FAQ
Do you work with ESP-IDF and Arduino?
ESP-IDF is the main focus. Arduino projects may be accepted after reviewing the existing code and requirements.
Can you connect my ESP32 to MQTT or a REST API?
Yes, subject to your broker or API details, authentication, network setup, and ESP32 variant. Share a protocol specification or test endpoint before ordering.
Can you implement BLE GATT or Wi-Fi provisioning?
Yes. I can implement custom BLE GATT behavior or supported Wi-Fi provisioning. Mobile app development is separate unless included.
Can you integrate sensors and peripherals?
Yes. Provide part numbers, datasheets, interface type such as I2C, SPI, UART, ADC, or GPIO, and expected behavior.
Will you test on real hardware?
Testing depends on package scope and hardware access. I will not claim physical validation if only code review or simulation was possible.
Can you add OTA, TLS, or low-power features?
Possibly, depending on the ESP32 model, memory, architecture, and requirements. These may need a custom offer.
What do you need before I order?
Send the ESP32 model, ESP-IDF version, source code if available, wiring or schematic, datasheets, API documentation, expected behavior, and logs.
Do you build cloud backends or mobile apps?
This Gig covers embedded firmware and device-side integration. Cloud backends and complete mobile apps are excluded unless separately agreed.
