esp_err_t uart_enable_pattern_det_baud_intr(uart_port_t uart_num, char pattern_chr, uint8_t chr_num, int chr_tout, int post_idle, int pre_idle);

Implemented in uart.c:607

Arguments

Argument

Description

uart_num

UART port number.

pattern_chr

character of the pattern.

chr_num

number of the character, 8bit value.

chr_tout

timeout of the interval between each pattern characters, 16bit value, unit is the baud-rate cycle you configured. When the duration is more than this value, it will not take this data as at_cmd char.

post_idle

idle time after the last pattern character, 16bit value, unit is the baud-rate cycle you configured. When the duration is less than this value, it will not take the previous data as the last at_cmd char

pre_idle

idle time before the first pattern character, 16bit value, unit is the baud-rate cycle you configured. When the duration is less than this value, it will not take this data as the first at_cmd char.

Return value

- ESP_OK Success - ESP_FAIL Parameter error
