I have been using the your WiFi module, The module desciption is below;

#  nv_manuf = ST

#  nv_model = SPWF01SA1

#  nv_serial = 4313D02202

#  nv_wifi_macaddr = 00:80:E1:FF:BA:10

+WIND:1:Poweron (141106-0950875-SPWF01S) (f/w version)

After socket write operation with''AT+S.SOCKR'' command, ''+WIND:55:Pending Data...'' is generated. UM1695 does not include any information about that issue.

I upgrate the firmware from 3.3(141106) to 3.5(160129)

I retest the module but got same result.

I attached the test outputs screen shot.

I already test two modules but the result is same.

    Hi,

    as a general rule, cannot be sent out wifi indications (WINDs) between the first incoming 'A' and the resulting OK/ERROR. Any indication is delayed until the end of the command.

    Then, about the reason of incoming data, seems server is echo-ing received packets. Is this possible?

    Can you please check with wireshark (sniffer) is server is sending something back to the client? Did you already tried with another server? e.g. linux netcat.

    Regards

    jerry
