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.

Dear colleagues,
I'm bit confused about the the TCP_WND option parameter.
First I understood that this value is the initial advertised TCP window
size. For instance, when I set it to 2*TCP_MSS, my advertised window in
the TCP header of the SYNC segment is matches 2*TCP_MSS. Also, we can se

So, I've got confused of the relation with TCP_WND with the sending
buffer and queue. I did not find anything relevant in the TCP output
functions. Just tcp_connect seems to also be using the value (maybe as
a initial parameter for the sending window?)
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

The tcp_connect part is clear. However I still dont understand:
"Window size (TCP_WND):

If memory allows it, set this as high as possible (16-bit, so 0x is the
highest value), but keep in mind that for every active connection, the full
window may have to be buffered until it is acknowled

Pretty amazing !
After a couple of weeks of fiddling (on my spare time) to write a port,
I have something functional !
The network interface driver was a bit complicated to write because it's
completely asynchronous so I had to write myself a multileaving (that's
a non preemptive multithread
