Bluetooth Tool vs KnockKnock PingPort

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. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Pro • Signal charts and limit analysis • Field inspection • Diagnostic packages • Evidence-based diagnostics • Run regression comparison • Diagnostic cases • iCloud sync Manually sync projects, captures, reports and cases between devices with the same Apple ID using iCloud Drive, preserving conflicting copies.

KnockKnock opens access to your servers with one tap. It sends the knock your firewall expects, a sequence of TCP and UDP ports or ICMP echo requests of agreed sizes, and shows each step as it goes. PORTKNOCK • Name, host (domain, IPv4 or IPv6) and an ordered list of ports, each TCP or UDP • Delay between ports from 0 to 1000 ms to fit your knockd timeout • Progress for every port, and the time of the last knock in the list PINGKNOCK • Ordered groups of ICMP echo requests: count × data size in bytes • The equivalent ping commands, to try the same knock from a terminal • A table of ICMP and IP packet sizes to match your firewall rule, such as iptables -m length or MikroTik packet-size • A warning when VPN or cellular networks may split large packets Works with knockd and any firewall that opens access after a sequence of packets. PRIVATE BY DESIGN • No account, no analytics, no ads, no tracking • Records stay on your iPhone unless you export them, and packets go straight to the hosts you enter FREE AND PRO The free version keeps one PortKnock server and one PingKnock target. KnockKnock Pro, a one-time purchase, removes the limit and lets you export and import your records as a file, to move them to another iPhone. No subscription. Port knocking hides a service but does not replace SSH keys or passwords.
