Chengdu Ebyte Electronic Technology Co., Ltd.

1、 The serial port chip must be a model that can support 3M baud rate. The company's test baseboard uses CP2102

series

2、 The serial port assistant software must be able to support 3M baud rate, the company's test software is XCOM2.6

3、 The connection between the module and the PC should not go through the USB converter, but directly connect to the

USB3.0 port of the PC, otherwise it is easy to lose packets

5.8 Heartbeat package, registration package

Heartbeat package registration package is a function only in TCP client mode. This module supports custom heartbeat

package data and registration package data content.

This module supports Modbus protocol and can realize free conversion between RTU and TCP. When in use, you only

need to pass in the data from the serial port, the module will automatically identify and convert it into data that conforms

to the Modbus specification and upload it to the network. Or convert the received network data into data that conforms to

the Modbus specification and output from the serial port.

requires attention：

1、 The Modbus supported by this module is only for data conversion and does not support actual functional

operations. If you need to use this part of the function, please cooperate with the actual PLC equipment.

2、 If the Modbus function is enabled, the protocol transmission is invalid, that is, the protocol transmission is no

longer data with a fixed format, and will be converted into data that conforms to the modbus protocol standard.

3、 Only the TCP server, TCP client, UDP, MQTT, WebSocket and P2P modes support the Modbus protocol, but

the HTTP client does not. The reason is that because the HTTP client is a short-connection communication

method, the server cannot actively initiate data exchange.

In STA mode, it can support setting static IP, which is convenient to realize the communication of fixed IP. It should be

noted that the static IP address must be in the same network segment as the target router or target AP, otherwise the IP

address cannot be assigned and it cannot work properly. For example, the target AP address is 10.123.45.1, then the static

IP address must be set to 10.123.45.x. Otherwise, the IP address cannot be assigned normally, and the module cannot

work. Static IP related parameters can only be set or queried in STA mode, other modes do not support corresponding AT

commands.

This module will only actively detect the level state of the GPIO14 pin within 3 seconds when it is powered on. If it is

low, it will restore the parameters to the factory default parameters. There is no need to restart when using, and the

GPIO14 pin will be set to low level after the parameters are restored successfully.
