Lwip packet processing is done in single thread and hence it's a sequential
operation for either incoming or outgoing packets. It may be true.

enter_critical is called in most systems and is not a mandatory requirement
either. Based on your implementation, You may simply return a 0 in protect

And right order has to be maintained for protect/unprotect calls e.g.
lev1 = sys_arch_protect()
lev2 = sys_arch_protect()
lev3 = sys_arch_protect()
sys_arch_unprotect(lev3)
sys_arch_unprotect(lev2)
sys_arch_unprotect(lev1)
Rest depends on how you actually implement these calls.

You can write a simple wrapper function for DNS setup and use

LwIP sockets are wrapper functions for netconn, compatible with BSD sockets. So
in order to use lwIP sockets, you need to enable netconn. And yes you can use
them both.

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.

Service providers do not assign public IPs to modems. They are usually behind
an ISP gateway. You need to talk to your ISP if public IP is needed. Rest
everything looks fine.

Hi Nishant,
It is normal for network providers to close PDP context. And 2hrs seems to be
common duration as per what I have tested. All you can do is simply reconnect.
Moreover IP provided by most service providers are not public so you wont be
