3.10 TCP/UDP transparent transmission channel function configuration
3.10.1 TCP/UDP address and port configuration
AT Command
AT+SOCKADDR =<addr>,<port>,<local_port>,<type>
\r\n
AT+SOCKADDR \r\n
(1) Socket0 address supports IP address and domain name, and the maximum byte length supports 50 bytes. Device
software restart, hardware reset and normal power-on automatically connect to socket0. To wake up the device from
deep sleep, you need to enter the command AT+SOCKONOFF to connect to socket0. If the server does not release the
link before connecting, the terminal needs to successfully disconnect the link first and then connect to socket 0.

<type>: 0 means TCP protocol, 1 means UDP protocol.
Note: When you need to save after power-off, input AT+NRB command to save the parameters to the flash, and
automatically restart to take effect..
(2) Socket connection status changes will be actively reported: AT+XSSTATE:<id>,<state>:
<id>: It means the created socket id, currently only supports 0 and 1, TCP/UDP channel can only use 0, COAP, MQTT,
Ebyte cloud uses 1.
<state>: It represents the socket connection status, 1 means connected, 0 means disconnected.
