With the development of the times and the advancement of technology, Bluetooth smart door locks have also rapidly gained popularity. 

Bluetooth smart door locks are deeply loved by consumers for their safety, convenience and speed. The market for Bluetooth smart door 

locks is vast. At the same time, the government's policy of vigorously calling for the construction of national smart communities has attracted 

many manufacturers to increase the research and development and investment of such products. Bluetooth smart door locks will become the 

most popular smart home products in the future.

Compared with the traditional smart lock unlocking method, the current Bluetooth smart door lock not only retains the traditional key unlocking, 

but can also be opened by fingerprint, password, magnetic card, mobile phone remote control and other methods. Most traditional smart door 

locks use network connection APP to unlock, which will show many disadvantages when there is no network. The addition of Daxia Longque 

Bluetooth module to Bluetooth smart door locks will solve this problem to a large extent. The chip has an integrated signal processor that can 

directly output the sensing control signal. It uses sound wave sensing to open the door without connecting to the network. In addition, it also 

supports the keyboard password input function on the door lock, IC card, key, etc. for manual unlocking. With higher precision, lower power 

consumption, smaller size, and more convenient integration, it is very popular.

This solution is based on the DX-BT24 Bluetooth module of DX-SMART
