Bluetooth contactless unlocking solution, unlock by proximity

Bluetooth-Based Intelligent Proximity Detection and Device Interconnection Solution

With the rapid development of intelligent devices, traditional unlocking methods such as keys and remote controls are gradually failing to meet users’ demands for convenience, security, and intelligent interactive experiences. Seamless unlocking technology uses Bluetooth communication to automatically connect devices and mobile phones. By detecting the phone’s Bluetooth signal strength (RSSI), it determines the user’s distance and automatically unlocks the device upon proximity, providing a more intelligent, secure, and efficient interactive experience for products such as electric vehicles, smart locks, and smart meters.

Based on years of experience in Bluetooth module R&D, Ansiot Technology has launched the ANS-BT101S Bluetooth contactless unlocking solution, the ANS-BT101L seamless unlocking PRO solution, and the ANS-BT301S seamless unlocking Ultra solution, covering various application needs such as basic seamless unlocking, intelligent control, data interaction, and intelligent cockpit displays, helping customers quickly upgrade their products to intelligent versions.

I. ANS-BT101S Seamless Unlock Solution

Basic Bluetooth Seamless Unlock Solution

The ANS-BT101S is a Bluetooth seamless unlock solution developed for smart locks, electric vehicles, scooters, charging stations, and other devices. It establishes a connection with a mobile phone via Bluetooth, acquires the phone’s signal strength in real time, and transmits the signal data to the device’s MCU. The MCU then determines the distance and automatically unlocks the device when the user approaches.

ANS-BT101S Core Functions

1. Automatic Mobile Phone Connection for Automatic Unlocking Upon Approach

The ANS-BT101S seamless unlock module supports automatic Bluetooth connection with mobile phones. When a user approaches the device with their paired mobile phone, the module automatically establishes a Bluetooth connection and detects the phone’s Bluetooth signal strength (RSSI). The module transmits RSSI data to the device’s main control MCU. The MCU determines the unlocking condition based on a preset distance threshold and, when met, automatically unlocks the device, achieving:

• Automatic phone proximity recognition
• No need to take out the phone to operate the app
• Automatic connection and distance judgment
• Improved user convenience

2. Bluetooth Data Transmission and Device Control

In addition to the contactless unlocking function, the ANS-BT101S supports Bluetooth data communication for device parameter reading, status control, and function expansion. For example:

• Mobile app reading device status
• App control of device functions
• Parameter setting and data interaction
• Advantages of the ANS-BT101S solution

1) Multi-platform compatibility, supporting multi-device binding. The ANS-BT101S supports mainstream mobile phone platforms, meeting the needs of different users.

Simultaneously supports the binding and management of up to 9 mobile devices, suitable for applications such as shared devices and multi-user use.

2) Safe and reliable, preventing unauthorized connections, the solution employs a binding mechanism:

• After the device enters pairing mode, only mobile phones are allowed to bind.
• Unbound devices do not print signal values.
• This prevents unauthorized connections from unknown mobile phones, improving device security.

II. ANS-BT101L Seamless Unlock PRO Solution

Intelligent Vehicle Solution with Integrated Tire Pressure Monitoring

The ANS-BT101L is a professional application solution upgraded from the ANS-BT101S. In addition to supporting seamless unlocking and Bluetooth communication, it can be expanded with Bluetooth tire pressure monitoring functionality according to customer needs. This solution is particularly suitable for electric vehicles, intelligent two-wheelers, and other vehicle products, enabling integrated intelligent vehicle entry, status management, and safety monitoring.
