Re: open source source code of static library libat_core.a
I'll ask the team to specify it a bit better, but I think it's safe to assume that libat_core.a is licensed under the same license as its include file (essentially MIT but only when used on ESP32 hardware). The sources for this library are not publicly available, sorry.

Re: open source source code of static library libat_core.a
You're trying to call printf from the interrupt handler. Very few functions can be successfully invoked from an interrupt handler and these in general have something like 'fromISR' in their name; printf is not one of them. For debugging, you can try ets_printf instead.
