Swyddogaethau sylfaenol

Set the IP / subnet mask / gateway

Y cyfeiriad IP yw cynrychiolaeth hunaniaeth y modiwl yn y LAN, sy'n unigryw yn y LAN, felly ni ellir ei ailadrodd gyda dyfeisiau eraill yn yr un LAN. Mae gan gyfeiriad IP y modiwl ddau ddull caffael: IP statig a DHCP / IP deinamig.
- static state IP
  Static IP needs to be set manually by users. In the process of setting, pay attention to write IP, subnet mask and gateway at the same time. Static IP is suitable for scenarios that need the statistics of IP and devices and need to correspond one to one. Pay attention to the corresponding relationship of IP address, subnet mask and gateway when setting. Using a static IP requires setting up for each module and ensuring that the IP address is not repeated within the LAN and on other network devices.
- DHCP / dynamic IP
  The main function of DHCP / dynamic IP is to dynamically obtain IP address, Gateway address, DNS server address and other information from the gateway host, so as to avoid the cumbersome steps of setting IP address. It is applicable to the scenarios where there are no requirements for IP, and it does not require IP to correspond to modules one by one.
  Nodyn: The module cannot be set to DHCP when directly connected to the computer. Generally, the computer does not have the ability to assign IP address. If the module is set to DHCP directly connected to the computer, the module will be waiting for IP address assignment, which will cause the module to carry out normal transtransmission work. The module default is static IP: 192.168.0.7.
The subnet mask is mainly used to determine the network number and host number of the IP address, indicate the number of subnets, and judge whether the module is in the subnet. The subnet mask must be set. The commonly used class C subnet mask: 255.255.255.0, the network number is the first 24, the host number is the last 8, the number of networks is 255, the module IP is within 255, the module IP is considered in this subnet.
Gateway yw rhif rhwydwaith y rhwydwaith lle mae'r cyfeiriad IP cyfredol. Os yw'r ddyfais fel y llwybrydd wedi'i gysylltu â'r rhwydwaith allanol, y porth yw cyfeiriad IP y llwybrydd. Os yw'r gosodiad yn anghywir, ni ellir cysylltu'r rhwydwaith allanol yn gywir. Os nad yw'r llwybrydd wedi'i gysylltu, nid oes angen ei osod.

Adfer Gosodiadau'r ffatri
AT instruction to restore factory setting: restore factory through AT + RESTORE. 6.2.3 Firmware upgrade
Y ffordd i uwchraddio'r firmware modiwl yw uwchraddio anghysbell OTA, a thrwy uwchraddio'r firmware, gallwch gael mwy o swyddogaethau cais.

Mae'r uwchraddio firmware yn cysylltu'r rhwydwaith naill ai trwy ffordd wifrog neu wifi.
Operation GPIO2 ground, restart the module and enter OTA upgrade mode.

Complete the upgrade, disconnect the GPIO 2 to the ground, restart the module, and the module enters the normal working mode.

Gosod swyddogaeth cyfarwyddyd AT
The user can enter the AT command to set the function of the module. Refer to the esp32 wired module AT instruction set for details.

Data transmission transmission function
The module has four data transmission ports: serial port, wifi, Ethernet, and Bluetooth. Users can combine the four data ports through AT instructions for data transmission transmission.
Sefydlu / holi sianel drosglwyddo'r modiwl trwy'r cyfarwyddyd AT + PASSCHANNEL. Mae'r gosodiad wedi'i gwblhau ac mae angen modiwl ailgychwyn i ddod i rym.

Swyddogaeth y soced
The Socket working mode of the module is divided into TCP Client, TCP Server, UDP Client, and UDP Server, which can be set by AT instruction. Please refer to the esp32 cable module AT command routine v 1.0.

Cleient TCP

TCP Client Provides a client connection for the TCP network services. Proactively initiate connection requests and establish connections to the server to realize the interaction between serial port data and server data. According to the relevant provisions of TCP protocol, TCP Client is the difference between connection and disconnection, thus ensuring the reliable exchange of data. Usually used for data interaction between devices and servers, it is the most commonly used way of network communication.

When the module is connected to TCP Server as TCP Client, it needs to pay attention to the parameters such as the target IP / domain name and the target port number. The target IP can be a local device with the same local area, or the IP address of different LAN or the IP across the public network. If the server is connected across the public network, the server is required to have a public network IP.

Gweinydd TCP
Usually used for communication with the TCP clients within the LAN. Suitable for a LAN where there are no servers and multiple computers or mobile phones request data from the server. There is a difference between connection and disconnection as TCP Client to ensure reliable exchange of data.

Cleient CDU

UDP Client A non-connected transmission protocol that provides a simple and unreliable information transmission service oriented to transactions. Without connection establishment and disconnection, you only need to make an IP and port to send the data to the other party. It is usually used for data transmission scenarios with no requirement for packet loss rate, small packets and fast transmission frequency, and data to be transmitted to the specified IP.

Gweinydd CDU
Gweinydd CDU Yn golygu peidio â gwirio'r cyfeiriad IP ffynhonnell ar sail CDU cyffredin. Ar ôl derbyn pob pecyn CDU, mae'r IP targed yn cael ei newid i'r ffynhonnell ddata IP a rhif porthladd. Anfonir y data i'r IP a rhif porthladd y cyfathrebiad agosaf.

Defnyddir y modd hwn fel arfer ar gyfer senarios trosglwyddo data lle mae angen i ddyfeisiau rhwydwaith lluosog gyfathrebu â modiwlau ac nad ydynt am ddefnyddio TCP oherwydd eu cyflymder cyflym a'u hamlder… Swyddogaeth porthladd cyfresol

AT gosod cyfarwyddiadau
Gall y defnyddiwr nodi'r gorchymyn AT i osod swyddogaeth y modiwl.

Trosglwyddo data porth cyfresol
Through AT instructions, the user can make the module into the data transmission mode, and the module can directly transfer the serial port data to the corresponding data transmission end (wifi, Ethernet and Bluetooth) through the set data transmission channel.

Swyddogaeth Bluetooth

Trosglwyddo data Bluetooth
Through the existing Bluetooth function of the module, the module can obtain Bluetooth data, and can directly transfer the Bluetooth data to the corresponding data transmission end (wifi, Ethernet and serial port) through the set transtransmission channel.

Swyddogaeth Wifi

Mynediad i'r rhyngrwyd
Module wifi is connected to the Internet or local area network through the router, and the user has to configure the socket function through AT instructions. The module can establish a TCP / UDP connection, which can access the user’s specified server.
