3.5.1.1. UART Application

If the host communicates with module via UART interface, the following preconditions should be met to let
the module enter sleep mode.



Execute

AT+QSCLK=1

to enable sleep mode.



Drive MAIN_DTR to high level.

The following figure shows the connection between the module and the host.

Figure 2: Sleep Mode Application via UART



Driving MAIN_DTR to low level by host will wake up the module.



When EC200T series has a URC to report, the URC will trigger the behavior of MAIN_RI pin. Please

refer to

Chapter 3.17

for details about MAIN_RI behavior.

3.5.1.2. USB Application with USB Remote Wakeup Function

If the host supports USB Suspend/Resume and remote wakeup functions, the following three
preconditions must be met to let the module enter sleep mode.



Execute

AT+QSCLK=1

command to enable the sleep mode.



Ensure the MAIN_DTR is kept at high level or kept open.



The host’s USB bus, which is connected with the module’s USB interface, enters Suspend state.

The following figure shows the connection between the module and the host.
