Bluetooth Serial Connect 2.0.0 is a complete rewrite built to make your hardware easier to control from iPhone and iPad.

Important for existing hardware projects: Version 2 uses a new typed wire protocol. Update your sketches to the Bluetooth Serial Connect Arduino library 2.0.0 and follow the migration guide at bluetooth.henhen1227.com. Your saved board files migrate automatically.

• Create and manage boards from the redesigned dashboard, then build richer layouts in the new free-form editor with drag-to-move controls, resizing, undo and redo, duplication, locking, grid snapping, and front-to-back ordering.
• Choose from nine component types: buttons, joysticks, sliders, toggles, D-pads, text displays, labels, indicators, and gauges. Assign channel numbers that stay fixed when controls move.
• Start faster with seven editable templates, companion Arduino examples, an interactive walkthrough, and simulated testing that works without hardware.
• Reconnect to remembered devices, configure custom service and characteristic UUIDs, and follow clearer scanning and connection progress.
• Inspect timestamped sent and received messages in the redesigned two-way console, and import, export, share, or duplicate boards as your projects grow.
• Unlock Bluetooth Serial Pro with a one-time purchase for unlimited boards and no ads.
