sim800L gprs post request
<p>I've been working on a LoNet mini GSM module (SIM800L), interfacing it with Arduino.
I've inserted the SIM mobile card with Internet connection available.
Through serial monitor I'm communicating with it with no problems, but when it comes to make a GET or a POST request to a webserver page it returns Network Error (601).
Here it is:</p>

<p>AT+SAPBR=3,1,"CONTYPE","GPRS"
OK</p>

<p>AT+HTTPINIT
OK</p>

<p>AT+HTTPPARA="CID",1
OK</p>

<p>AT+HTTPPARA="URL","http://:8080/folder/savedata.php"
OK</p>

<p>AT+HTTPACTION=0
OK
+HTTPACTION: 0,601,0      //601: Network Error</p>

<p>AT+HTTPREAD=1,100000
OK</p>

<p>And no response of the "echo" of the php page...
Do you have any suggestion?
Thanks in advance.</p>
