<![CDATA[How to detect button press with blocking call.]]>While using BLE features the scanning for services method uses a blocking call. During that time a button press is not caught using M5.BtnA.wasPressed(). However the button press needs to be recorded and handled after returning from the blocking call.
Is that possible and how? I am using Arduino in Visual Studio IDE.
Any suggestions are welcome.

Combining the two answers solved my problem. Split the work over two cores and added a suggested delay between calling M5.BtnA.wasPressed() and it seems to work as hoped for. Did not use the interrupt solution though interesting.
