We are looking for an experienced Java developer to help integrate a custom protocol for device communication. The project requires expertise in data protocols, XOR checksum calculations, and byte-level data handling, specifically with handling escape characters in communication protocols.

Project Scope:

Protocol Integration: Implement a custom communication protocol in Java to enable reliable data exchange with our device.

Checksum Calculation: Calculate XOR checksums based on specific fields in the protocol and ensure compatibility with the device's checksum.

Escape Processing: Apply escape processing for special bytes (e.g., 0xE7 and 0xE6) to avoid conflicts with message start/stop bytes.

Byte Manipulation: Use Java ByteBuf (Netty framework or similar) for precise byte handling, including constructing and parsing messages.

Key Tasks:

Encode and Decode Messages: Construct messages according to protocol specifications, including start/stop bytes, message type, properties, and checksum.

Validate Checksum: Ensure that checksum calculations match the device’s expectations.

Apply Escape Rules: Properly handle escape sequences to ensure data integrity during transmission.

Troubleshoot Communication Issues: Work with our team to diagnose and resolve checksum mismatches or data inconsistencies.

Requirements:

Strong Java skills with experience in data communication protocols.

Experience with checksum calculations, particularly XOR checksums.

Familiarity with byte manipulation using ByteBuf or similar libraries.

Understanding of escape sequences and byte-level data handling.

Ability to work independently and troubleshoot complex protocol-related issues.

Additional Information: You will work with our team to ensure the device's communication is reliable, error-free, and follows the protocol specifications.
