Good Afternoon,
I am doing an application for ESP32 (32D).
In order to avoid high power compsuptions I am using 2 functions with RTC I/O's.
For example, with GPIO 0:
rtc_gpio_init(GPIO_NUM_0);
rtc_gpio_isolate(GPIO_NUM_0);
As I told before, I am using this 2 functions with all RTC I/O's.
The power compsuption is incredibly low, but the problem is that I
use GPIO's 32 and 33 as UART and when my ESP32 comes back from Deep Sleep
the UART TX doesn´t work unless I comment the lines for isolating GPIO's 32 and 33
(I don´t see no message sniffing with a Serial USB after Deep Sleep).
Could you help me to de-isolate the GPIOS before it awakens from Deep Sleep?
I configure the GPIO's each time that the app is started/re-started but it doesn´t work.
Thanks in Advance, best regards.
Jorge.
