Serial.readBytes() is a function in Arduino that enables the reading of a specified number of bytes from the serial buffer and saving them into an array buffer. This function can be used to read binary data, such as sensor readings, from an external device connected to the Arduino board. ...

Add radio function to read the radio syncword uint16_t syncword = Radio.GetSyncWord(void); 2025-01-01 Add custom Syncword and Low DataRate optimization Add radio function to set a custom Syncword Radio.SetCustomSyncWord(uint16_t syncword); ...
Arduino 1.0 introduced a number of Serial enhancements and changes : Serial.flushnowwaits for all outgoing data to be sent rather than discarding received data. You can use the following statement to discard all data in the receive buffer:while(Serial.read() >= 0) ; // flush the receive ...
