open source source code of static library libat_core.a

[jothinathan]

This is just a query. I am looking for following details.

Where to find source code
license of libat_core.a

[ESP_Sprite]

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.

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.
