DSD TECH Bluetooth is now diBlue. Version 2.4 updates the same app under its new name; existing users can update their current installation. diBlue is a practical workspace for compatible Bluetooth Low Energy devices and DSD TECH relay modules. Discover devices, exchange Text or HEX data and keep frequently used commands close at hand. FIND AND ORGANIZE DEVICES - Scan nearby BLE devices and view their names and signal strength. - Save favorites and assign local aliases without changing the hardware name. - Switch between All and Favorites, view device details and choose a device type. - Copy a device's iOS UUID from its details. This identifier is not its hardware MAC address. - Hide unrelated devices from discovery results and restore them from Settings when needed. SEND COMMANDS AND REUSE YOUR WORK - Send and receive Text or HEX data. - Send once or repeat at a chosen interval, with a stop control. - Choose None, CR, LF or CRLF line endings for text commands. - Reuse recent commands from History and save frequently used commands in Starred. - Selecting a saved command fills the input for review; it does not send automatically. - Read color-coded send and receive logs, with optional timestamps and automatic scrolling. CONTROL COMPATIBLE DSD TECH RELAYS - Detect the channel count on supported one- and four-channel modules. - View device-reported channel states and refresh them when needed. - Control individual channels or use All on and All off on four-channel modules. - Confirm control results through a follow-up status query to the device. CHOOSE YOUR LANGUAGE AND DISPLAY PREFERENCES The interface supports English, Simplified Chinese, Traditional Chinese (Taiwan), German, French, Spanish (Spain), Italian, Portuguese (Portugal) and Japanese. Follow your system language or choose a language in Settings. You can also keep the screen on while connected and adjust log timestamps and automatic scrolling. LOCAL STORAGE, NO ACCOUNT REQUIRED diBlue contains no ads and requires no account. Device profiles, favorites, aliases, settings, command history and starred commands are stored locally. Apple-managed backups and device transfers may preserve this data according to your settings. COMPATIBILITY Requires iOS 15 or later and compatible BLE hardware. Classic Bluetooth SPP devices are not supported. Data transfer requires the supported FFE0 service and FFE1 characteristic; relay controls require the supported DSD TECH relay protocol. diBlue does not work with every Bluetooth device. Bluetooth permission is required to discover and connect to nearby devices. The app does not request location permission. Support: dsd_tech@outlook.com
