Hi, There is condition to perform “SSEND” command. First, UART DATA must be entered in 3 seconds. Also, Total length of the data want to send, must be input within 10s + (Total Length)ms. If both of the above conditions are not met, Timeout occurs. Thanks.

thanks for your answer, but i don’t understand when the timer start. I think, the timer start after this command AT+SSEND and not before. Example: https://wizdaniel.wordpress.com/2015/08/17/wizfi250_ssl_connection/ [code]AT+SSEND=0,146 [0,146] SEND DATA HTTP/1.1 200 OK Server: nginx Content-Type: text/html; charset=utf-8 Google [OK][/code] The answer for this example is [0,146] and not [ERROR: INVALID INPUT] I have 1s beetween AT+SCON=O,TSN,5000,0 and AT+SSEND=0,146 i try to insert less.
