Intro

IS2540XSR and IS2541XSR BLE Modules are developed to implement wireless

communication possible only at outside of door for a Digital Door Lock(DDL) system.

D1 and D2 cannot work standalone. They need to be controlled by main MCU on digital

doorlock main board.

How to connect to DDL Main board and how it works

D_1

D_2

DDL MAIN BOARD

When people touched doorlock Main board wakes D_1 to transmit BLE signal to the front.

At the same time D_1 send a signal to D_2 to transmit a different signal to disturb

smartphone to get normal BLE signal at the back side of DDL.

D_1 is just normal BLE module. D_2 is just making a RF signal when D_1 transmit any RF

signal.

In the data point of view, D_1 just transfer the date from smart phone to DDL Main Board

only after D_1 and Smartphone have made BLE connection.
