BLE Relay Bluetooth — Control your motorcycle contact over Bluetooth.
iPhone app to configure and control a Bluetooth Low Energy (BLE) motorcycle relay module such as A72Z / XY-MBO21F (often named NBH-…) and compatible relays. Approach to unlock, walk away to lock — without a complicated proprietary box.
• SCAN & CONNECT
Find nearby modules, connect in one tap, and monitor live RSSI signal strength.
• CONTACT ON / OFF
Turn the motorcycle contact on or off from the app. On A72Z modules, contact follows proximity thresholds (ULRSSI); connecting alone does not turn the contact on.
• PROXIMITY DISTANCE (1–10 m)
Set the activation range. Approach to unlock, move away to lock — according to your module setup.
• AUTO-CONNECT
Optionally reconnects to your last saved module when within about 10 m, including background use.
• MODULE SETTINGS
Adjust PIN, name, RSSI thresholds, TX power, modes, on-site calibration and advanced options for the detected protocol.
• MULTI-PROTOCOL
Supports several BLE relay families (A72Z proximity, A0 checksum, transparent UART, DSD TECH, ZL / TwoSwitch, generic GATT) with assisted detection.
• SIRI & SHORTCUTS
Say “Turn on the motorcycle” / “Turn off the motorcycle” with Siri (iPhone or Apple Watch with iPhone nearby). Keep the app in the background for more reliable Bluetooth.
• WIDGET
Quick On / Off controls from the Home Screen.
• MULTILINGUAL
UI available in many languages.

A compatible BLE relay module (e.g. A72Z / XY-MBO21F). Bluetooth enabled. Factory PIN is often 123456.
PERMISSIONS
Bluetooth is required to scan, connect and configure the module.
PURCHASE
Paid app: all features included. No additional In-App Purchases.
