BillyGate firmware
BillyGate is a little bluetooth-low-energy (BLE) dongle that connects chess e-boards (like the Square Off Pro) to chess apps like chess.com and lichess.org. See What is BillyGate?
Download the firmware (low-level software) that powers BillyGate.
- LATEST v0.1.7 firmware - promotion/under-promotion, faster internal chess logic.
Follow the BillyGate set-up instructions. First-time set up requires one more interaction with BillyGate support: you need to send us a board ID (that uniquely identifies the Pico2W you bought) and we return you a token that authenticates your firmware for use on that board.
Archive firmware:
- v0.1.5 - added virtual LED feature.
- v0.1.4 - first stable release.
- flash_nuke.uf2 - use this (as instructed by BillyGate support) to factory-reset BillyGate.
- Firmware downgrades are possible, after a BillyGate factory-reset.
