Re: Capacitive touch example?

There is only one rtc interrupt so it has to be shared (similar to gpio interrupt). You could implement an isr service like gpio to have separate callbacks per pin. Arduino already does this so you could use that code.

Re: RMT: RX input and xRingBufferAddToQueueSetWrite ...

Right I guess you could request getter functions for the semaphores or a compare function.

Re: RMT: RX input and xRingBufferAddToQueueSetWrite ...

Yes I believe ringbuf library is made by @esp_sprite Once you receive the matching handle you can compare it to the handles you think it could be to figure out which member to operate on. But consider: http://www.freertos.org/Pend-on-multiple-rtos-objects.html#alternative_design_pattern which may or...

Re: empty ssid with bssid_set to true

What is the code on line 172?

Have you tried setting ssid on both ap and sta to 32 nul bytes?

Re: What is PHY as it relates to ESP32?

What is a potential use case where we would not want the PHY layer initialized? What are the implications of manually initializing it? If you aren't ready to use the radio and want to save power. If you want to set calibration mode. Use a partition to store PHY init data - What is considered to &qu...
