![]() This affects some functions such as Serial::available() and Serial.read() because, in a UART flow of receiving data, Serial internal setRxFIFOFull(uint8_t fifoBytes) will set the number of bytes that will trigger UART_INTR_RXFIFO_FULL interrupt and fill up RxRingBuffer Void setRxTimeout( uint8_t symbols_timeout) For a baudrate of 9600, SERIAL_8N1 (10 bit symbol) and symbols_timeout = 3, the timeout would be 3 / (9600 / 10) = 3.125 ms For example symbols_timeout=1 defines a timeout equal to transmission time of one symbol (~11 bit) on current baudrate. Examples: Maximum for 11 bits symbol is 92 (SERIAL_8N2, SERIAL_8E1, SERIAL_8O1, etc), Maximum for 10 bits symbol is 101 (SERIAL_8N1). If set above the maximum, it is ignored and an error is printed on Serial0 (check console). Maximum timeout setting is calculacted automatically by IDF. Setting 0 symbol timeout disables the callback call by timeout. param symbols_timeout defines a timeout threshold in uart symbol periods. setRxTimeout sets the timeout after which onReceive callback will be called (after receiving data, it waits for this time of UART rx inactivity to call the callback fnc) Pay attention: the baudrate returned by baudRate() may be rounded, eg 115200 returns 115201 ![]() Serial.println("No baudrate detected, Serial1 will not work!")
