BLE Relay Bluetooth

Your iPhone becomes the key. Walk closer—your relay turns ON. Walk away—it turns OFF. Set 1–10m proximity, multi-protocol support, built for bikes, smart switches & DIY.

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.

REQUIREMENTS 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.

Note: results depend on the module, radio environment and distance. Test in a safe place first.
