[TCP Send Error]

Hello

I have found undocumented AT Response [TCP Send Error].
This is the response to unsuccessfull AT+SSEND command. What is the meaning of this response?

Hi, oyoyoy.

If the response message doesn’t arrive from tcp server after sending the request message.
WizFi250 can wait some setting time and print [TCP Send Error].

Thanks.

do we need to consider this message as an real error or just “need more time” ?

please, what must we do if we get this message ??
or sometime, i do not receive reply after a AT+SEND message (my SEND function allowed timeout of 1000ms for this message)

thanks

WIZFI250 FW 1.0.3.3

Hi

You have to check [OK] response when you send AT+SCON.

Thanks.
