HLK-RM58S Serial/UART 2.4G/5G WIFI+BLE Development Kit

HLK-RM58S Serial/UART 2.4G/5G WIFI+BLE Development Kit

HLK-RM58S Serial/UART 2.4G/5G WIFI+BLE Development Kit has a built-in It has a UART-WIFI module. (serial-Wireless network). This product is an embedded module based on serial interface in line with the network standard, built-in TCP/IP protocol stack, which can realize the user's serial port-to-wireless network (WIFI) conversion. Thanks to the HLK-RM58S module, the traditional serial device can transmit its own data over the Internet network without changing any configuration, which provides a complete and fast solution for the user's serial port device to transmit data over the network.

Product Modes

STA Mode

·In this mode (STA mode), the settings Via COM1 and WiFi data can be mutually converted.

·WiFi security supports the current major encryption methods.

AP Mode

·In this mode (AP mode), COM1 and WiFi data can be mutually converted through the settings.

·The WiFi device can connect to the product and become a device under WiFi LAN.

·WiFi security supports all available encryption methods.

TCP Server

·In this mode, the module monitors the specified port and waits for the TCP Client to connect. After the connection, all TCP data is sent directly to the serial port, and data from the serial port is sent to all TCP Clients.

When the module is used as a TCP Server, it supports up to 2 TCP Clients to connect to the TCP Server.

TCP Client

·In this mode, the module connects to the specified domain/IP and port. All data sent from the TCP Server end is sent directly to the serial port, and data from the serial port is sent to the TCP Server end.

· Abnormal network will cause the product to actively reconnect. When TCP active reconnection is present, the TCP Server actively disconnects and the product immediately actively reconnects, otherwise the module will not reconnect.

UDP Server

·In this mode, the module opens the locally specified port. After the data sent to this port is received, the module will send the data to the serial port and record the remote IP and port.

The module will only record the remote information of the last connection. Data received by the serial port will be sent directly to the recorded remote IP and port.

UDP Client

·In this mode, the module sends serial port data directly to the specified IP and port. Data returned from the server will be sent to the serial port.
