Function Structure
Work Mode
Transparent Transmission Mode
Data is transmitted transparently between serial port and Wi-Fi / Ethernet via DR404, enabling data transfer between serial port device and network device
Serial Command Mode
The user sends data to the server according to the protocoland can send data to different servers without restarting.
httpsD Client Mode
After the user completes the https header with an AT instruction or web page setup, DR404 can pass data to or from the https server.
AT Command Mode
Users can query the current status of DR404 or set relevant parameters by sending AT instructions
Quick Networking Protocol USR-LINK
Mobile phone connect to the AP of DR404,you can directly
set the specified AP to which DR404 connects by querying
surrounding AP’s SSID list through USR-LINK, which is
convenient and fast. You can quickly connect to the Internet
without operating DR404.
