I am facing one peculiar type of problem with newly purchased wemos d1 mini. Before my last stocks of wemos d1 mini inventory ran out everything was working fine with our loT based codes. But these new purchased wemos d1 mini seems to have problem with exactly same codes. Mainly they are giving exception 0 and 4.
If this manufacturing problem or I am missing anything?
I am using arduino IDE.
Thanks for your time.
