Deskripsi Produk

HLK-M20 is a high cost-effective embedded serial port-WiFi transparent transmission module developed and produced by Hilink Electronics.

This product is an embedded module based on the universal serial interface and conforming to the network standard. The built-in TCP / IP protocol stack can realize the conversion between the user serial port and the wireless network (WIFI) interface, and can connect the serial port to the network TCP / UDP Transparently transmit data.

Through the M20 module, the traditional serial device can transmit its own data through the Internet network without changing any configuration. Through simple configuration, a variety of networking methods and network connection types can be customized to provide a complete and fast solution for users' serial devices to transmit data through the network.

Two working states of the module

The M20 WiFi module has two working states: transparent transmission mode and AT command mode.

In the AT command mode, you can send AT commands to the M20 module through the serial port, configure the working parameters of the module, and query the information of the module.

When in the transparent transmission mode, the M20 module will automatically connect to the network according to the parameters configured by the user, establish a TCP / UDP connection, and transparently transmit the data between the network connection and the serial port; It is sent as transparent data to the corresponding TCP / UDP connection.

The module automatically enters the transparent transmission mode when it starts.

Module test board

Users can choose our special test board to quickly start testing and using M20 modules. The test baseboard is directly powered by USB, with its own USB to serial port function. After connecting to the computer through the USB cable, it can be connected to the serial port of the module through the USB to serial port. There is no need to connect an additional serial cable, which is convenient to use.

The appearance of the test board is as follows:

Typical application

In an environment with a wireless router, WiFi wirelessly accesses serial devices. After the mobile phone is connected to the wireless router, the APP on the mobile phone can directly send and receive data with the serial device to achieve status query or control functions. Multiple mobile phones can control one device; The mobile phone can access the external network through a wireless router.
