Modem-Sleep：Used for scenarios where the CPU has been working, such as the application
of PWM or I2S applications.When maintaining a Wi-Fi connection, if there is no data transfer,
the Wi-Fi Modem circuit can be turned off to save electricity based on 802.11 standards (such
as u-apsd).For example, at DTIM3, keep the sleep 300ms, wake up 3ms and wake up to
receive the AP's Beacon package,the current is about 15mA.
Light-Sleep：Applications for cpus, such as Wi-Fi switches.When maintaining a Wi-Fi
connection, if there is no data transfer, you can turn off the Wi-Fi Modem circuit and stop the
CPU to save power according to the 802.11 standard (such as U-APSD).For example, at DTIM3,
a sleep 300ms is maintained, and a Beacon packet that wakes up to receive an AP from every
3ms is about 0.9 mA.
Deep-Sleep：Applied to does not need to always keep a Wi-Fi connection scenario,the
application of a long time to send a packet(e.g.,every 100 seconds measure time temperature
sensor),per 300s we wake up to 0.1s-1s connected to the AP,the overall average current can
be far less than 1mA.

uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
FCC Radiation Exposure Statement
The modular can be installed or integrated in mobile or fix devices only. This modular cannot be installed in any portable device, for example,
USB dongle like transmitters is forbidden.
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located
or operating in conjunction with any other antenna or transmitter. This modular must be installed and operated with a minimum distance of 20
cm between the radiator and user body.
If the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the
module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:
“Contains Transmitter Module FCC ID: 2AMPSOSL-ESP8266M4Or ContainsFCC ID: 2AMPSOSL-ESP8266M4”
when the module is installed inside another device, the user manual of this device must contain below warning statements;
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause undesired operation.
2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the
equipment.
The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that
