What's New in Bluetooth Serial Connect

2.0.0

July 20, 2026

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.

not functional - scanning does not work

app is non functional, when scanning for devices the progress wheel spins indefinitely.

App support unavailable

Hello, I tried emailing the developer for this application and I received a “Address Not Found” in response. My question was whether this app also supported raspberry pi’s.

Response from developer

Hi there! Apologies for the issue with our email—this was due to a temporary server migration, but everything should be up and running now. Regarding your question, while the app is designed to communicate directly with BLE Bluetooth chips like the HM10, it wasn’t specifically developed for use with Raspberry Pi. It may still work, but you might need to handle some of the data encoding and decoding on your end. If you encounter any issues or need further assistance, feel free to reach out at support@henhen1227.com.
