ERROR
If the UDP transmission is already established, the response is:
ALREADY CONNECTED
Parameters
• <linkID>: ID of network connection (0~4), used for multiple connections.
• <type>: string parameter indicating the connection type: "TCP", "UDP"
• <remoteIP>: string parameter indicating the remote IP address.
• <remote port>˖remote port number.
• [<UDP local port>]: optional; UDP port of WizFi360.
• [<UDP mode>]: optional. In the UDP transparent transmission, the value of this
parameter has to be 0.
▶ 0: the destination peer entity of UDP will not change; this is the default
setting.
Example
AT+CIPSTART=”UDP”,”192.168.4.10”,9527,9527,0
10.3.2.3. AT+CIPSEND
Commands
1. Single connection: (+CIPMUX=0)
AT+CIPSEND=<length>
2. Multiple connections: (+CIPMUX=1)
AT+CIPSEND=<link ID>,<length>
3. Remote IP and ports can be set in
UDP transmission:
AT+CIPSEND=[<link ID>,]
<length>[,<remoteIP>,<remote
port>]
Function: to configure the data length in
normal transmission mode.
AT+CIPSEND
Function: to start sending data in
transparent transmission mode
Response
Send data of designated length. Wrap
return > after the Set Command. Begin
receiving serial data. When data length
defined by <length> is met, the
transmission of data starts. If the
connection cannot be established or gets
disrupted during data transmission, the
system returns:
ERROR
If data is transmitted successfully, the
system returns:
SENDOK
Wrap return > after executing this
command. Enter transparent
transmission, with a 20-ms interval
between each packet, and a maximum of
2048 bytes per packet. When a single
packet containing +++ is received,
WizFi360returns to normal command
mode. Please wait for at least one second
before sending the next AT command.
This command can only be used in
transparent transmission mode which
requires single connection. For UDP
transparent transmission, the value of
<UDPmode> has to be 0 when using
AT+C IP START.
