    Socket client: use '',ind'' parameter to SOCKON command to get an indication when something was received.

    Socket server: automatically switches to data mode when something was received. Note that socket server has no AT commands.

    Use Hands-On manual to get some example

    Hi,

    I observed followings while communicating between two Wi-Fi 4click modules:

    • At the Client side when its try to connect to server I’m using AT+S.SOCKON command to connect.

    • In this command I can pass “indâ€� parameter which can indicate data arrival at the client side with “+WIND:55:Pending Dataâ€� on UART interrupt .

    • Client side it is taking 500ms to receive WIND:55:Pending Data: interrupt.

    • Server to client data transmission it takes only 5 to 6ms.

    Please suggest how to solve this time delay at the client side.

    Thank you
