SIM800 ...GPRS spojeni

[Jaroslav Buchta]

Ja nekde nasel tento postup a pro SIM808 fingoval.
Nelogicky bylo dulezite AT+CIFSR, jinak to neslo.


=> AT
<= AT /** This should come back. SIM900 default is to echo back commands 
you enter **/
<= OK /** This string should tell you all is well**/
=>AT+CPIN? /**This is to check if SIM is unlocked. This sample assumes 
unlocked SIMs**/
<= +CPIN: READY /** If your response contains this, then it means SIM is 
unlocked and ready**/
=>AT+CREG? /**This checks if SIM is registered or not**/
<=+CREG: 0,1 /**This string in the response indicates SIM is registered**/
=>AT+CGATT? /**Check if GPRS is attached or not**/
<=+CGATT: 1 /**A response containing this string indicates GPRS is 
attached**/
=>AT+CIPSHUT /**Reset the IP session if any**/
<=SHUT OK /**This string in the response represents all IP sessions 
shutdown.**/
=>AT+CIPSTATUS /**Check if the IP stack is initialized**/
<=STATE: IP INITIAL /**This string in the response indicates IP stack is 
initialized**/
=>AT+CIPMUX=0 /**To keep things simple, I’m setting up a single 
connection mode**/
<=OK /**This string indicates single connection mode set successfully at 
SIM 900**/
=>AT+CSTT= “APN”, “UNAME”, “PWD” /**Start the task, based on the SIM 
card you are using, you need to know the APN, username and password for 
your service provider**/
<= OK /**This response indicates task started successfully**/
=> AT+CIICR /**Now bring up the wireless. Please note, the response to 
this might take some time**/
<=OK /**This text in response string indicates wireless is up**/
=>AT+CIFSR /**Get the local IP address. Some people say that this step 
is not required, but if I do not issue this, it was not working for my 
case. So I made this mandatory, no harm.**/
<= xxx.xxx.xxx.xxx /**If previous command is successful, you should see 
an IP address in the response**/
=>AT+CIPSTART= “TCP” , “www.vishnusharma.com”, “80” /**Start the 
connection, TCP, domain name, port**/
<= CONNECT OK /**This string in the response indicates TCP connection 
established**/
=>AT+CIPSEND /**Request initiation of data sending (the request)**/
<= > /**The response should be the string “>” to indicate, type your 
data to send**/
=> xxxxxx /**Just type anything for now**/
=>#026 /**Now type the sequence #026. This tells the terminal.exe to 
send the hex code 0x1a (which is Ctrl+Z) to indicate end of data sending**/
<= xxxxxxxxxx /**You should get some response back from the server…it 
would generally be a complain that the request string was not valid…but 
that is a different subject…you have established the connection**/
/**To close the connection**/
=>AT+CIPSHUT /**Request shutting down of the current connections**/
<=SHUT OK /**Indicates shutdown successful**/
