Bluetooth Debug Tool brings BLE connections, communication records and protocol analysis into one workbench for hardware, software and embedded engineers. Included tools • Scan BLE peripherals, inspect advertisements and RSSI, and save aliases and favorites. • Explore services and characteristics, read and write HEX or UTF-8, and subscribe to notifications. • Trace individual devices and characteristic instances. Filter by receive origin, prefix, byte pattern, offset or length. • Save captures, export TXT and CSV, and filter or replay sessions offline. • Keep one free project with TX/RX channels, decode fields and filter settings. • Frame fixed-length, delimiter-based and length-field protocols; check SUM, XOR and CRC; decode SLIP and 7E/7D byte escaping. • Use numeric formulas, an offline script sandbox, flow editing and previews. Editing and previews do not send commands. • Use iPhone tab navigation or the iPad sidebar and detail workspace, with light/dark appearance and Dynamic Type. Optional Pro • Multiple projects and configuration import. • Execute command loops, variables and conditional branches with write acknowledgments and response-prefix checks. • Capture records before and after an incident trigger. • Compare last received values and GATT structure snapshots. • Run a single-service virtual BLE peripheral with read, write, notification and echo support. Lifetime access, monthly subscriptions and yearly subscriptions unlock the same Pro features. See the purchase screen for current localized prices and periods. Subscriptions renew automatically. Cancel future renewals in system subscription settings; access continues through the current paid period. Restore purchases is available. Data is stored locally by default. Imports, exports and sharing are initiated by you. Live communication requires compatible BLE hardware and Bluetooth permission. Scripts use a restricted numeric language. Virtual peripherals and flow execution run in the foreground. Prefix matches and Bluetooth write acknowledgments do not prove device-level business success. Available in 20 interface languages, including Arabic with right-to-left layout.
