Send user data. User data is sent once the
data length reaches the segment length
specified by parameter 10 of IPCFL. If the user
data length is shorter than the specified length,
the data will be sent when the timer set by
parameter 5 of IPCFL counts down to 0. For
details about the transmission mechanism,
refer to the description of ^IPENTRANS in the
AT command document.
In this example, the data entered by the user is
313233347D5D7D5E7E in hexadecimal format.
The data sent by the module is the original data
entered by the user.
Receive user data in time- and length-based
transmission mode. In this example, the data
received by the module is
313233347D5D7D5E7E.
The original data received by the module is
presented.
Exit transparent transmission mode. For the
rules about the +++ sequence, refer to the AT
command document.
Set the transparent transmission mode to 7E
detection mode.
Enable transparent transmission mode.
Query the link ID for entering transparent
transmission mode from a non-transparent port.
Send data in 7E detection mode (applies to
UDP only). In this example, the data that the
user wants to send is 313233347D7E in
hexadecimal format. Therefore, the user needs
to transform 7D to 7D5D and 7E to 7D5E, and
adds 7E as the ending characters to the end of
the data.
After the module recognizes the data packet,
the data actually sent by the module is
313233347D7E.
