ESP32 MTDI Pin consideration.

I have an ESP32D0WDQ5 (revision 1). I have been reading up on the strapping pins but I cant find a reliable documentation for this part of this chipset. 1) Can I use MTDI pin as an input (Deep sleep Wakeup). 2) If not can I use it as output? 3) Should I consider keeping it pulled up? Any advantage/d...

Ext1 Wake up using input only pins

Hi,
Is it possible to use the input only pins, 34 to 39 as ext1 wake up sources and be able to detect which pin was used to wake up? esp_sleep_get_ext1_wakeup_status(); seem to return 0 for these pins.

Raw data is more accur...
