I am using sim 800 GSM/GPRS module . When I try to connect it to the Internet through gprs connection,it acquires connection(network LED blinking fast)and for all commands,module responds ‘OK’.After these all when I try to pass this, (AT+HTTPPARA=“URL”,"http://group35.epizy.com/hardware.php?sid=1&field=name), it doesn’t response back with “OK”.Can you help me to recognize the reason for this?Thanks in Advance.
Here are the order of the commands I tested before above mentioned command and their responses.
ATE0 -> OK
AT+SAPBR=3,1,“CONTYPE”,“GPRS” -> OK
AT+SAPBR=3,1,“APN”,“ppwap” -> OK
AT+SAPBR =1,1 -> OK
AT+HTTPINIT ->OK
AT+HTTPPARA=“CID”,1->OK
Normally we dont use http:// in entering URL. We start from group35…
And check if you are ending it with double quote after name".
See if you are exceeding URL length.
Sir,What did you mean by saying ‘see you are exceeding URL length’.I didn’t quite get it.can you explain it?
Now I manage to set URL.but I’m getting JS code as data instead of response I expected.Can you tell me what is the reason for that?Thanks.
May be your page is returning the JS code. Try doing a GET request though Fiddler and see in raw format what is returned.
With the aid of fiddler, I was able to find that it is returning JS file called aes.js.But I never had such file and I am hosting it on a free web hosting service.Then I used this (http://192.248.12.7/~174084f/hard.php) as a test and it works perfectly in the browser and fiddler but no information is received by the GSM module.What may be the reason for that?Thanks.
Finally I managed to solve the error.Thank you for your support upto now.Thanks in advance.
I am facing same problem. Can you tell me how to solve that problem. #pavindu_lakshan
When you’re finding a solution to a problem it would better to better to be humble and write the answer here for helping others.
Those days I was really busy with a hardware project at my university and really close to a deadline, so I didn’t have any time to post solutions in forums. However, its been 3 years now since then and I haven’t touched a single GSM module in that past. Therefore, I don’t really remember the solution. Sorry about that.
