Read lessThe current Espressif voice solution can meet the environmental requirements of a signal-to-noise ratio of less than 5dB, and for some fixed noise scenarios, it can also be less than 0dB (need to be optimized for the actual product).

I am testing “esp_sleep_enable_uart_wakeup” function.
I have connected to UART0 (GPIO3 U0RX, GPIO1 U0TX) an external LTE module and I would like to wake up ESP32 when it is in light sleep but the external module send a particular string on the UART0.
I have done a very simple test. It seems to work, but as soon as I change these configuration for CONSOLE debug output from the default to the below ones:
CONFIG_CONSOLE_UART_DEFAULT= CONFIG_CONSOLE_UART_CUSTOM=y CONFIG_CONSOLE_UART_NONE= CONFIG_CONSOLE_UART_CUSTOM_NUM_0= CONFIG_CONSOLE_UART_CUSTOM_NUM_1=y CONFIG_CONSOLE_UART_NUM=1 CONFIG_CONSOLE_UART_TX_GPIO=25 CONFIG_CONSOLE_UART_RX_GPIO=27 CONFIG_CONSOLE_UART_BAUDRATE=115200
It doesn’t work. I would like to use UART1 to send out the debugs because UART0 is occupied to talk with the external module: but the changes in the SDK config (only the one reported above) seems to be the cause of the issue.
How to solve the issue?

I have an Espressif ESP32 running a lighting circuit.
When I switch the circuit on the ESP gets power and the ESP is programmed to switch on a relay (connected to a light) in the setup routine.
The relay switch-on is practically the first command after initializing the GPIO pins in the setup routine.
My problem is that on some occasions the relay switches on within 500ms of the circuit being powered (which is acceptable) and other times there is a delay of about 20-30 seconds before the relay is activated.
What would cause this and how can I fix it?
