 When a TCP Server Socket set, can support up to four TCP Client TCP link connection.

In a multiple TCP link connection mode, from the TCP transport data will be forwarded to them one by one on the UART interface. Come from the UART interface data will be copied into a more, in every TCP forwarding a link. Specific data flow diagram shown below:

When the module working in TCP or UDP Client Client mode, the user can open registration packet mechanism, in order to realize the server to the distinction between the data source, data of different equipment monitoring. MAC and ID registration packet is divided into two kinds, MAC is 6 bytes, ID 0-65535, ID value can be set. Registration packet ID is mainly used for the D2D software of the company..

Registered packet opened and closed by

Registered packet implementation mechanism is as follows:

 TCP Client: There are two kinds of TCP Client: registration mechanism:

1 Just send a registration packet, when the module is connected to the TCP Server

module will send TCP Server MAC (6 bytes) or ID (4 bytes), Server by MAC or ID to distinguish between different devices.

2 Every packet of data has registration information, TCP Client after the link to the server,

a serial port receives each packet of data to increase MAC or ID, to distinguish between equipment. ID or MAC choice, can be set by the

 UDP Client: each module on the sending UDP packets, MAC or ID will increase in each

packet header information, and then send.

Fast Access

When one module works in AP mode, it opens a UDP port used to receive fast access Wi-Fi

commands, the port number is 49000. The phone PDA can directly connect to Wi-Fi network of

the module, send commands to search router list and set SSID and password. After the

completion of set up, module will automatically restart, connected to the router, work in the STA

mode at this time.

Introduction

Modules can open low power mode. In module under normal condition, if the network and

uart port for certain time 10-240 seconds

(AT

+ SLPTYPE Settings) does not data

communication module into low power mode. The user can choose different sleep mode (0 to

4). Ways there are to awaken the network side and serial port: network side refers to establish

the wifi connection, to establish a socket connection with module and send data to the socket, a serial port end points to a serial port to send data.

For example: set up

AT

+ SLPTYPE = 2,200

When the module network end (refer to the socket end) and a serial port for 200 seconds

didn't receive the data, the module into Deepsleep mode (mode 2).
