Android Coin-Bill Emulator

@AwaisChaudhry

Hello, I will deliver an Android-based emulator that looks and behaves like a coin validator and a bill reader, exposing both USB and Bluetooth without host changes, and speaking ccTalk as a master. The system will generate configurable pulse trains, support coin and note values, and reply to host polls with correct status. Deliverables: APK, complete source, optional bridge firmware for a small MCU, wiring diagrams, BOM, Gerbers, and a concise test script to prove pulse and ccTalk on real hardware. Approach: - Implement a lightweight ccTalk master in the Android app, with a deterministic pulse generator and a small state machine for coin/note config. - Provide an optional bridge path for a microcontroller with clear APIs; USB and Bluetooth will share a single device interface. - Include thorough documentation and a repeatable test procedure to validate both USB and Bluetooth modes. Technical questions for you: Which ccTalk version and host expectations should I target, and would you like separate addresses for coin and bill functions with both USB and Bluetooth available? Do you prefer a specific MCU/bridge hardware, or should I design for a generic ARM-based module? What pulse timing tolerance and power supply specs must the harness meet? Are there any security or signing requirements for the APK or firmware? Any preferred deployment milestones or acceptance criteria that I should align to? Which ccTalk version and host expectations should I target, and would you li

Hi! I have extensive experience developing Android-based hardware emulation solutions that interact seamlessly with legacy interfaces. I can build your system to: * Emulate standard pulse trains for coins and bills with configurable values * Speak ccTalk as a master, fully compatible with the host’s polling commands * Present itself simultaneously as coin validator and bill reader * Expose both Bluetooth and USB without requiring host changes Questions: 1. Do you already have a microcontroller in the loop, or should I recommend one for USB/ccTalk bridging? 2. Is there a preferred Android device class or OS version for the emulation? Best regards, Houssame

@Alanfox10000

Hi, I can build the Android-based solution you’re describing. The app will emulate both pulse-train and ccTalk protocols, with a configurable UI for mapping coin/note values. It will support dual-mode I/O: USB: Android device will expose itself as a USB peripheral to the host, emulating coin/bill acceptor behaviour using USB-serial or HID if required. Bluetooth: For wireless testing, the same logic will run over a Bluetooth SPP profile, acting as a transparent bridge for ccTalk and pulse events. Core deliverables: APK: Android app with selectable mode (coin/bill, pulse/ccTalk), value setup, and test triggers. Source code: Fully commented, ready for future changes. Hardware bridge (if needed): If Android USB access isn’t sufficient for precise pulse timing, I’ll provide firmware for a microcontroller (e.g. Arduino Pro Micro or STM32) to act as a timing-accurate bridge. Wiring diagrams + BOM: For connecting Android device (via OTG or Bluetooth) to host validator harness. Test script: Simple Python or shell tool to simulate polling and capture output. Gerbers: If a custom board is needed, I’ll provide ready-to-fab files. Let me know which host device you’re testing against (e.g. vending machine controller, arcade logic) and the ccTalk address ranges used. I can start immediately and iterate with real hardware-in-the-loop testing.
