Bluetooth GATT Service for Digital IO Control

Problem Statement

The current ESP32 firmware for the Supra LCD Controller lacks a Bluetooth GATT service to facilitate the activation and deactivation of digital IO pins. This feature is essential for enabling external control and automation of the digital IO functionality, enhancing the versatility and accessibility of the Supra LCD Controller.

Who will benefit?

Users and developers working with the Supra LCD Controller will benefit from this feature, especially those looking to integrate and control digital IO pins remotely through Bluetooth-enabled devices.

Benefits and Risks

Benefits:

  • Remote Control: Users can remotely activate and deactivate digital IO pins using Bluetooth-enabled devices.
  • Automation Integration: Facilitates seamless integration with automation systems and external control applications.
  • Enhanced Versatility: The Supra LCD Controller becomes more versatile with the addition of Bluetooth GATT service for digital IO control.

Risks:

  • Implementation Complexity: Considerations for robust error handling and security must be addressed during implementation.

Proposed Solution

Implement a Bluetooth GATT service in the ESP32 firmware for the Supra LCD Controller to enable the activation and deactivation of digital IO pins. This service should include characteristics for controlling individual digital IO pins and provide appropriate notifications or responses to acknowledge state changes.

Examples

Similar Bluetooth GATT services for device control can be found in various IoT and home automation projects.
