Basic operation

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 under 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, highfrequency analog, power wiring), 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. Isolation and shielding.

| Methods|

Description

---|---|---
0| Module to module communication| Module 1 is set to AP mode and establishes TCP or UDP server, module 2 is set to STATION mode and connected to AP 1, and communicates with module 1 through TCP or UDP Client
1| Module and Server communication| The Wi-Fi module is connected to the network through a wireless router, and communicates with a server on the network (LAN or Internet) through TCP Client or UDP.
If you need to connect to an Internet server, you need to configure the corresponding port mapping on the router.
2| Module and Client communication| The Wi-Fi module connects to the network through a wireless router and establishes a TCP or UDP Server to listen to the connection signal. Client communicates with it through the connection module server.

GPIO configuration

In the E103-W05 series of modules, GPIO0 /1/6/7/8/9/10/11/12/13/14/15/16/17/18 are used as ordinary GPIO, among which, E103-W05A can only use GPI015 and GPI016. When we want to control the output level of the relevant pin through the AT command, or read the relevant level status, we can use the following commands.

AT+CIOMODE to set the working mode of GPIO

Instruction format:
AT+CIOMODE =, : pin label;
: working mode; 1:
Output mode
0: input mode

AT+CIOWRITE to set GPIO electrical level

Instruction format:
AT+CIOWRITE=, :
pin label;
: working mode;
1: High level
0: low level

AT+CIOREAD to read GPIO electrical level

Instruction format：
：pin label；

Pin application example

Use GPIO18 as output attribute and output low electrical level
AT+CIOMODE=18,1
AT+CIOWRITE=18,0
Use GPIO18 as input attribute and read out electrical level
AT+CIOMODE=18,0
AT+CIOREAD=18

Serial port baud rate setting

When users use E103-W05, they often set the serial port baud rate. The module supports the following baud rates： 2000000， 1500000，1250000，1000000，921600，406800，230400，115200，57600 38400，19200，9600，4800，2400，1800，1200，600；

In the configuration of the upper computer, the 115200 and 9600 setting buttons are provided. If the user’s setting requirements cannot be met, the relevant AT commands can be used to set the baud rate. After the baud rate is set, it will take effect immediately.

FAQ

Communication range is too short

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 results near the ground are poor;
Sea water has a strong ability to absorb radio waves, so the seaside test results are poor.
If there is a metal object near the antenna or placed in a metal shell, the signal attenuation will be very serious;
The power register setting is wrong, the air speed setting is too high (the higher the air speed, the closer the distance);
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 matching degree of the antenna and the module is poor or the quality of the antenna itself is problematic.

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, the module will be permanently damaged.
Please check the stability of the power supply, the voltage should not fluctuate greatly and frequently.
Please ensure anti-static operation during installation and use, and high frequency components are electrostatically sensitive.
Please ensure that the humidity during installation and use should not be too high, and some components are humidity sensitive.
If there is no special requirement, it is not recommended to use it at too high or too low temperature.

Cautions

The relationship between AP &STA&Server&Client

During the 2 network access processes in the above quick user manual, 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 only modules connected to the network. One of the working modes of the module, and TCP Server, TCP Client and UDP can create network links in any mode of the module.

Caution 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 must remember to manually use AT+CIPSEND to activate the transparent transmission. If the user wants to boot for transparent transmission, you need to use the AT command “AT+SAVETRANSLINK” for related settings. For details, please refer to the AT command manual.

The maximum number of connections between AP connection and server connection

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, and when the module is working in TCP Server mode, it can be connected by at most 5 TCP Clients. Therefore, it is recommended to use when the customer performs short packet data or does not consider packet loss. UDP carries out relevant communication.

AT command

The AT commands used by the 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.
