I will develop esp32 iot firmware with mqtt nrf, ble, and cloud dashboard
About this Gig
Need ESP32 IoT firmware that connects, reports data and stays reliable? You're in the right place.
I develop custom ESP32 and nRF firmware with MQTT, BLE and a live cloud dashboard, so your device can send data, receive commands and be monitored from anywhere.
What I build:
- ESP32 firmware (Arduino IDE, PlatformIO, ESP-IDF)
- MQTT integration (Mosquitto, HiveMQ, AWS IoT, Home Assistant)
- BLE and nRF connectivity, including mobile app pairing
- Cloud dashboards for real-time monitoring and control
- Sensor, relay, display and motor integration over I2C, SPI and UART
- OTA updates, low-power modes, debugging and optimization
Why buyers choose me:
- Clean, commented code you fully own
- Wiring diagram and setup guide included
- Fast replies and clear milestones
- Tested on real hardware before delivery
Which package is right for you?
- Basic: one sensor or function, with a simple connection
- Standard: multi-sensor firmware with MQTT or BLE and documentation
- Premium: the full system with a cloud dashboard, OTA updates and post-delivery support
Message me with your board, sensors and goal before ordering, and I'll recommend the best fit. thanks
