Hey,

Please give the log of the ppp as well as your code to initialize the lwip stack. Your at commands sequence look fine. You must not call "at+cgact=1,1" since ppp stack does this functionality

Dev,

 

I think before entering data mode you need to activate the PDP context using AT+CGACT=1,1

So before msg8 you need to send that command.

 

Try it.

Hello Sylvain,

 

This are the commands I am using before PPP session --->

 

#define msg  "AT\r\n"

#define msg1  "ATZ\r\n"

#define msg2  "ATE0\r\n"

#define msg3  "AT+CFUN=1\r"

#define msg4  "AT+CNMI=0,0,0,0,0\r"

#define msg5  "AT+CPIN?\r"

#define msg6  "AT+CREG?\r"

#define msg7  "AT+CGDCONT=1,\"IP\",\"internet\"\r"

#define msg8  "AT+CGDATA=\"PPP\",1\r"

 

After msg8 I have received the CONNECT response & after that the PPP session starts.

 

I need to enable the LWIP debug.
