Chapter 4 Basic Operation
4.1 Hardware design
It is recommended to use a DC stabilized power supply to supply power to the module. The power supply ripple
coefficient is as small as possible, and the module needs to be grounded reliably;
Please pay attention to the correct connection of the positive and negative poles of the power supply. Reverse
connection may cause permanent damage to the module;
Please check the power supply to ensure that it is within the recommended power supply voltage. If it exceeds the
maximum value, it will cause permanent damage to the module;
Please check the stability of the power supply, and the voltage should not fluctuate greatly and frequently;
When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the
margin, and the whole machine is conducive to long-term stable operation;
The module should be as far away as possible from the power supply, transformer, high-frequency wiring and other
parts with large electromagnetic interference;
High-frequency digital wiring, high-frequency analog wiring, and power wiring must avoid the bottom of the
module. If it is necessary to pass under the module, assume that the module is soldered to the Top Layer, and the top
layer of the contact part of the module is covered with copper (all copper And well grounded), it must be close to
the digital part of the module and routed in the Bottom Layer;
Assuming that the module is soldered or placed on the Top Layer, it is also wrong to randomly route the wires on

the Bottom Layer or other layers, which will affect the stray and receiving sensitivity of the module to varying
degrees;
Assuming that there are devices with large electromagnetic interference around the module, it will greatly affect the
performance of the module. According to the intensity of the interference, it is recommended to stay away from the
module. If the situation permits, proper isolation and shielding can be done;
Assuming that there are traces with large electromagnetic interference around the module (high-frequency digital,
high-frequency analog, power wiring), it will also greatly affect the performance of the module. According to the
intensity of the interference, it is recommended to stay away from the module. Isolation and shielding；
4.2 Software writing
The module chip solution is Winner Micro W600, and its driving method is completely equivalent to W600, and
users can operate according to the W600 chip book;
The GPIO port of the internal chip is a general I/O port, which can be controlled by related AT commands；

Chapter 6 Frequently Asked Questions
6.1 The transmission distance is not ideal
When there is a straight line communication obstacle, the communication distance will be attenuated accordingly;
Temperature, humidity, and co-frequency interference will increase the communication packet loss rate;
The ground absorbs and reflects radio waves, and the test effect is poor near the ground;
Sea water has a strong ability to absorb radio waves, so the seaside test effect is poor;
If there are metal objects near the antenna or placed in a metal shell, the signal attenuation will be very serious;
The low voltage of the power supply at room temperature is lower than the recommended value, the lower the voltage,
the lower the power output;
The poor matching degree of the antenna and the module or the quality of the antenna itself。
6.2 Module is easy to damage
Please check the power supply to ensure that it is within the recommended power supply voltage. If it exceeds the
maximum value, it will cause permanent damage to the module;
Please check the stability of the power supply, and the voltage cannot fluctuate significantly and frequently;
Please ensure that the installation and use process is anti-static, and high-frequency components are electrostatically
sensitive;
Please ensure that the humidity should not be too high during installation and use, and some components are
humidity sensitive devices;
If there is no special requirement, it is not recommended to use at too high or too low temperature.
6.3 Matters needing attention
6.3.1 The relationship between AP&STA&Server&Client
In the above two network access examples in Sections 6.2 and 6.3, it is not only in AP mode that TCP Server can be
established. Similarly, it is not only when the module is in STA mode that TCP Client can be established. AP and
STA are just modules that access the network. A working mode of the TCP Server, TCP Client and UDP can create
network links in any mode of the module.
6.3.2 Note for transparent transmission
The transparent transmission mode can only be used when the module is working in TCP Client and UDP. TCP
Server cannot enter the transparent transmission mode. After entering the power-on transparent transmission, you

Chengdu Ebyte Electronic Technology Co., Ltd. E103-W05B User Manual
Copyright ©2012–2018，Chengdu Ebyte Electronic Technology Co., Ltd
must remember to manually activate the transparent transmission with AT+CIPSEND. If the user wants to boot For
transparent transmission, you need to make relevant settings in the following interface.
6.3.2 The maximum number of connections between AP and server
When establishing TCP Server and TCP Client, pay attention to the option of opening and closing multiple
connections;
When the module is used as an AP, it can be connected by at most 5 STAs. When the module is working in TCP
Server mode, it can be connected by at most 5 TCP Clients. Therefore, it is recommended for customers to use
short packet data or without considering packet loss. UDP carries out relevant communication.
6.3.2 AT commands
The AT commands used by E103-W05 series sub-modules (E103-W05A, E103-W05B, E103-W05C) can be used
mutually, but users must make relevant settings according to the electrical characteristics of their own modules. In
addition, due to different electrical characteristics, E103- W05 series modules are not fully compatible with the AT
commands of E103-W01. Therefore, some AT commands applicable to E103-W01 are not fully applicable to
E103-W05. For the detailed AT command set, please refer to the manual "E103-W05 AT Commands" Collection
Guide.
