User manual

set as UDP client. The differentiation between client and server is not clear in the
UDP protocol, but in this case it means that you will send data from your controller
to the computer.
The message
has been successfully transmitted.
To send data, use the command:
AT+CIPSEND=7
The 7 means the number of characters to be sent. The character > is returned.
This means that you can now send your message. Enter Hello and confirm with
[Enter]
again. The module returns SEND OK, although you have only entered
five characters. This is because after your input, Carriage Return and New Line
are sent as well, i.e. two characters more that you need to include in your mes-
sage length calculation.
When you switch back to the Packet Sender and look at Traffic Log there, you can
see the receipt of the message. In the ASCII view, you will even see the two en-
closed characters, represented by \r and \n.
