Re: source code for esp_wifi_scan_start()

IMHO there is no such. You can find some notes in this thread speaking about ROM content.

Re: UART TX Ring Buffer Fill Level

Would not uart_tx_chars function fit for your needs? According to docs (have not checked the source), it should return immediately when the TX FIFO is full, returning number of bytes enqueued.

Re: Brownout voltage level

Where are defined brownout voltage level on esp-idf ? The level is defined by the CONFIG_ESP32_BROWNOUT_DET_LVL_SEL project configuration option. Is it possible to change the default values ? Only for test purpose No, because the voltage levels are fixed in HW by enumeration values of the RTC_CNTL_...

Re: Choosing flag in bottleneck function: bool or int?

Not an answer, but a note; you may get disassembly by yourself. Because so long you really want the best optimization for your code, you should consult generated assembler code anyway.

Re: how to cancel (stop) a piece of code?

You can use a timer from which you would send the data in turn for each LED with every tick. And such timer you'd then control from button interrupt routine.

Re: How do I stop a timer?

And I suppose to restart the same timer later when I need it, I'll do: timer_start(TIMER_GROUP_0, TIMER_1); right? That's correct. You may find both methods used e.g. in this example . Any idea why the documentation says: esp_err_t timer_pause(TIMER_GROUP_0, TIMER_1); but in fact we don't need this...
