Hi MADHURI

Maybe you can use our ppp script to test PPP function.

hello Duncan,

as per your suggestion and script provided, we have added AT commands for activating PDP context but we are getting error for AT+CGDCONT=1,“IPv4”,“AirtelInternet”,0,0 command.

find the complete log for your reference

You have already used AT+QICSGP to configure the APN and IP type. Why do you use AT+CGDCONT to repeat the configuration? You can follow the script I provided to implement PPP dial-up
Copy quectel-chat-connect quectel-chat-disconnect quectel-ppp to the /etc/ppp/peers directory.

And modify your serial device name in quectel-ppp, the username and password used for pppd dial-up.

Modify your APN in quectel-chat-connect. APN/username/password is obtained from your network provider.

Then use the following command to start ppp dial-up. The & at the end of the command can make pppd run in the background.

pppd call quectel-ppp &

Hi Duncan,
Appreciate your quick response.
We are using only one command now as you have suggested.
we are going through the script provided by you.
Also, one thing we would to bring to your notice that we are configuring free RTOS in cyclone PPP.
Also we are using NXP IDE on windows as our host environment and application is running on NXP controller.
we have given all AT commands as mentioned in quectel-chat-connect(logs attached) Please let us know if we are missing anything in our understanding.

We are not getting any IPCP(NCP) packets or CHAP authentication packets from EC20 once LCP configuration is successful. If Authentication is enabled, EC20 is authenticator and application is supporting CHAP MD5 which EC20 is sending in LCP config packet. But, it is not sending any packet for challenge further.
If we skip authentication, EC20 is not sending any IPCP configuration packet when application is retrying to send IPCP configuration packets.

posting logs below for your reference.

Thank you .
Regards,
Madhuri
