The E103-W02 has 4 power consumption modes: Active, Sleep, LPDS, and Hibernate, which can be changed to the
corresponding low-power mode by sending the AT+PM command. For example: AT+PM=1,5

Mode 0: Active mode
All peripherals of the module are operating normally. This is the normal operating mode, where the module has the
best performance and the fastest response time. Mode 1: sleep mode
The module can be woken up by serial port or network packet, the gpio port keeps output, and the module
continues to run from sleep after waking up. Wake-up mode: serial RXD, network
Mode 2: Lpds mode
The module enters lpds mode, the network part remains running, and the module gpio port output is high
resistance. The module can be woken up by serial or network packets, and the wake-up packets are transmitted normally.
To send packets at this time, you need to send a serial short data to wake up the module first, and then you can send data
normally after the module wakes up. When there is received network data, the data will be output directly through the
serial port. Wake-up mode: serial RXD, network
Mode 3: Hibernate mode
When the module enters hibernate mode, both the network and MCU enter hibernate mode, and the gpio port outputs
high resistance state, so it can only be woken up by serial data. After waking up, the module restarts and runs. The
power consumption can reach below 5uA. Wake-up mode: serial RXD
Tips.
1, AP mode is set to low-power mode, the module will not enter low-power mode immediately after starting, and will
only enter low-power mode after connecting to the network (as AP mode, there are devices connected to the module).
2 、 Receiving network data and serial data will refresh the delay time to enter the low-power mode. For example, in
hibernate mode, after the user sends serial data to wake up the module and waits to connect to the server, it can
continuously send data for a long time without worrying that the module will re-enter hibernate mode. When the serial
port or network data reception is complete, the delay into low-power mode timing starts immediately, and the module
re-enter hibernate mode after reaching the delay time.
3, low-power mode all IO are in high resistance state, so the status indicator is disabled, will not reflect the current
actual connection status.

Remark
The E103-W02 module supports AP mode (equivalent to a router), STATION
mode (equivalent to a Wi-Fi device) as a physical connection role. The E103-W02
module supports AP mode (equivalent to a router), STATION mode (equivalent to
a Wi-Fi device), and up to 1 Wi-Fi device in AP mode.
The E103-W02 module includes TCP Server, TCP Client and UDP in the socket
role. TCP-based connection mechanism, please note that TCP heartbeat packets
should be used if you need to be connected for a long time.
