Simon,
Thank you for highlighting the potential conflicts with 'sockets.h' and for
recommending the use of accessor functions for 'ip_addr'. We are applying these
insights in a test environment to evaluate their impact on our existing issues.
I will keep you updated on our progress and any significant outcomes.
For your reference, here are the links to the lwiplib.c and lwiplib.h files
we're currently working with:
lwiplib.c:

Best,
Timothy
