I am in Electrical Engineering industry for 4 years, in fact, I love to mess with electronic components, theory and applications of EE. For me, it is the queen of all Engineering branches, what you say?
@alowhum most of these questions are way too advanced for me to answer, but I know that wait() calls _process() which processes messages and kicks the watchdog (through doYield()). See https://github.com/mysensors/MySensors/blob/development/core/MySensorsCore.cpp#L565
while (hwMillis() - enteringMS < waitingMS) {
_process();
}
By default, nrf24-based nodes do not use interrupts for message handling.
There is nothing done in parallell.
