Re: [lwip-users] LWIP/PPPOS for GSM module

[Devanand Biradar]

Hello Sylvain, 

I have corrected my input & output serial driver.

Now I am getting the IP addr, GW, subnet from GSM using PPPOS over LWIP.

Status - CONNECTED.

Now I want to use PING (using ICMP).

I want to ping google.com, how to proceed in this.

I want the steps to perform.

Thanks

You are obviously having an issue with your output serial driver.

And you are obviously having an issue with your input serial driver.


I wonder why you even asked what the issue is considering it could not
be written more clearly in the debug trace.
