The INDICATE pin remains low when the module is working normally. If the module has an abnormal INDICATE pin

outputting a high level, the module needs to be restarted at this time.

5.6 Low power consumption

The low power consumption of the module enables the module to enter the sleep state through command operation. After

entering the sleep state, it can be woken up through the pin. The wake-up method is to give a rising edge to the WAKEUP

pin (ie GPIO_13), or the serial port receives data.

Regarding high-speed transmission, the following issues need to be paid attention to:

1. The serial port chip must be a model that can support 3M baud rate. The company's test baseboard uses FT232 series

2. The serial port assistant software must be able to support 3M baud rate. The company's testing 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.

4. The module is connected to a computer or mobile phone, which can realize 3M transmission rate. However, when the

module is connected to the module, it may be necessary to reduce the baud rate of the transmitting end. The specific

amount to be reduced is limited by the influence of the connection distance and requires actual testing.

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 data on the network side 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 turned on, the protocol transmission will be 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.
