◆ load_settings() [1/2]

virtual void esphome::uart::UARTComponent::load_settings ( )

inlinevirtual

Load the UART settings.

Example:

id(uart1).load_settings();

id

uint16_t id

Definition dns_server_esp32_idf.cpp:0

This will load the current UART interface with the latest settings (baud_rate, parity, etc).

Reimplemented in esphome::uart::ESP8266UartComponent, and esphome::uart::IDFUARTComponent.

Definition at line 174 of file uart_component.h.

◆ load_settings() [2/2]

virtual void esphome::uart::UARTComponent::load_settings ( bool dump_config )

inlinevirtual

Load the UART settings.

Parameters

dump_config If true (default), output the new settings to logs; otherwise, change settings quietly.

Example:

id(uart1).load_settings(false);

This will load the current UART interface with the latest settings (baud_rate, parity, etc).
