CIPSend
(1) Input the service data to send
The data to send is stored in array variable A.
If only certain elements are specified in array var-
iable A, specify the number of elements in varia-
ble B.
(2) Store received response data
The data that is received is stored in variable C.
The byte size of the data that was actually re-
ceived is stored in variable D.
If the service data (
ServiceDat) is
Array[2] and number of elements
(
Size) = 2, Array[2] and Array[3]
are sent.
