▞ Function Desciption

Function	Description
Positioning	Supports single/continuous positioning modes (continuous not recommended for e-bikes due to high power consumption). Remote command for real-time location. Supports GPS/GLONASS/BD (optional).
2G/4G Communication	Remote monitoring of location, battery level, temperature; remote setting of max. speed, low-battery alerts (requires controller support).
WiFi Positioning	WiFi-assisted positioning (optional).
UART Communication	UART communication with controller (lock as host, controller as slave).
Bluetooth Unlock	BLE 4.0. App scans QR code → command sent to server via user’s network → server sends unlock command to App → App unlocks via Bluetooth.
Network Unlock	App scans QR code → lock sends command to server via network → server sends unlock command to lock.
OTA Updates	Remote firmware updates via server; supports controller updates (requires controller support).
Vibration Detection	Built-in accelerometer detects vehicle movement. Sends alert to server when vibration detected while locked.
Fault Reporting	Reports vehicle faults to server (requires controller support).
