About this gig

Need a wearable that can sense data, show it on a screen, and communicate with an iPhone? I can turn the concept into an ESP32-based BLE prototype with firmware, display control and mobile communication.



The design can combine an ESP32 with an OLED, motion or health-related sensors, battery power and BLE data exchange. I can adapt the architecture to your enclosure, sampling needs and workflow.



Development can cover:

  • ESP32 firmware and sensor drivers
  • BLE services and data transfer
  • OLED menus, status screens and live readings
  • Sensor integration and real-time acquisition
  • Battery, charging and low-power operation
  • iOS BLE communication and test-app integration
  • Data logging and device configuration
  • Schematic, PCB planning, BOM and documentation



This service fits fitness trackers, research wearables, smart bands, connected badges, motion devices and health-monitoring prototypes. The goal is to make sensing, display and wireless communication operate as one system.



Share the sensors, ESP32 variant, OLED size, iOS requirements, battery limits, and enclosure dimensions.
