IS2540XSR and IS2541XSR Manual

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.

Module configuration

D_1 : IS2540XSR with Antenna D_2 : IS2541XSR with Antenna

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

doorlock 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.
