MAC=xxxxx WSTATE=CONNECTED MODE=AP BSSID=xxxxx SSID="xxxxxx" CHANNEL=11 SECURITY=WPA2-PERSONAL RSSI=-49 IP addr=192.168.1.11 SubNet=255.255.255.0 Gateway=192.168.1.1 DNS1=192.168.1.1 DNS2=0.0.0.0 RxCount=68 TxCount=65848 [OK] AT+SETTIME=21/01/2014,19:20:44 21:1:2014 19:20:44 AT+DNSLOOKUP=m.google.com IP:74.125.128.193 [OK] AT+NCTCP=74.125.128.193,80 [ERROR: INVALID INPUT] ``` I keep getting the same error, on LAN as well. Pinging however works fine. Any solutions? ### Reply 6 by ssekim, 2014-01-22 I think that there are some mistyping or something like that in your test. Generally, “[ERROR: INVALID INPUT]” means wrong-format-parameter as below. [quote]at+nctcp=4.4.4.4,77 [ERROR] at+nctcp=4.4.4.4, [ERROR: INVALID INPUT] [/quote] ### Reply 7 by ojo, 2014-01-24 I keep getting spam report issue, and do not let me reply. I was wondering if this is common on the firmware. Since only this command has ‘INVALID INPUT’ I tried with different software terminals and parameters, all other commands work fine. Any other solution for this issue? ### Reply 8 by ssekim, 2014-01-26 What is your F/W version? How about try it again with latest F/W version? You can download that in the below link.
