Convert ADPU Script to ATR

Job ID: 40498266

Budget: $10 – $30 USD

I have a Python-based script that has been packaged into an .exe and currently pushes data out using an ADPU-style transmission. I now need that same codebase to send and receive using ATR transmission instead.

The core of the job is to modify the existing data-transmission format—no protocol swap or major architectural overhaul, just a precise refactor so every outbound and inbound message complies with ATR rules while the surrounding logic remains intact.

You will receive:
• The full script source that was frozen into the .exe
• Sample ADPU request/response pairs and the matching ATR specification I must follow

Deliverables I expect:
• Updated Python code with clear comments highlighting every line touched
• A rebuilt .exe that runs on Windows 10 just like the current one, only now talking ATR
• A brief change log so I can trace each alteration and verify compliance against my test vectors

If you spot edge cases where ADPU and ATR diverge—especially around header length, checksum placement, or end-of-frame markers—please surface them early so we can lock the format down together. Tests or mini-scripts that prove the new behaviour will be appreciated.

Let me know your estimated turnaround and any clarifications you need on the ATR spec files before you dive in.
