Automatic Unlocking with Phone Proximity: Making Travel Smarter and More Convenient

Driven by the wave of smart technology, traditional keys are gradually being phased out, and people are demanding more seamless, convenient, and secure unlocking methods. Today, a new unlocking solution—"Automatic Unlocking with Phone Proximity"—is gradually becoming a part of our daily lives.

1. What is "Automatic Unlocking with Phone Proximity"?

In simple terms, it is an intelligent unlocking solution based on low-power Bluetooth (BLE) technology. The user only needs to keep the paired phone in their pocket or bag. When they approach a device (such as a smart lock, e-bike, or shared parking lock), the system automatically recognizes and unlocks the device without manual operation and without taking out the phone, providing a "seamless unlocking" experience.

2. Core Advantages

◉ True Seamless Experience: No need to unlock the phone or press the App; just approach, and the device will unlock automatically, providing a smooth and natural experience.

◉ Safe and Reliable: The system uses an encrypted authentication mechanism, ensuring that only the paired device can initiate the unlocking request, and supports binding up to 9 devices.

◉ Low Power Consumption: Bluetooth communication consumes very little power, minimally affecting device battery life, making it particularly suitable for e-bikes, access control systems, smart bags, and other scenarios.

◉ Multi-Platform Compatibility: Supports mainstream mobile operating systems (iOS & Android), and can be seamlessly integrated with platforms like WeChat mini-programs and Apps, making it easy to deploy and promote.

3. Wide Range of Application Scenarios

1. Smart Locks: In residential buildings, hotels, apartments, offices, etc., users can open doors with their phone in their pocket.
2. Shared/Smart E-Bikes: Unlock by proximity for more efficient and convenient cycling.
3. Smart Parking Locks: Car owners can lock and unlock the parking space automatically as they approach, saving time and effort.
4. Smart Parcel and Storage Cabinets: The system recognizes the user's proximity and automatically opens, giving faster access.
5. Smart Luggage: Ensures the safety of luggage while making travel more convenient.

4. Solution Implementation

Based on our experience with the mature Bluetooth module RHA-BT101M and mobile communication protocols, we provide a complete "Automatic Unlocking with Phone Proximity" hardware and software solution.

1. Send AT+BOND=1\r\n to put the Bluetooth into pairing mode. It will exit automatically after 1 minute if there is no connection.
2. Once the paired phone connects, it reports RSSI every second in the format: \r\n+RSSI=1,Phone MAC address,Signal strength\r\n, used for distance judgment.
3. After reconnecting, the paired phone can send data to the App/Mini Program via AT+LESEND=Length,Data\r\n (e.g., AT+LESEND=5,12345\r\n).

Automatic unlocking with phone proximity is not just a technological innovation but a leap forward in human-computer interaction. It makes every unlocking experience easier, smarter, and more secure. Feel free to contact us for technical solutions and sample trials!
