Description
Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino. I have the option of configuring the serial mode on both ends. While I cannot decrease the baud rate for bandwidth reasons, I do have enough room to enable parity or a larger stop bit if that would help. Granted the corruption is on the serial line and not on the Bluetooth, if I enable parity, will this actually decrease the corruption rate?
Arduino Serial Parity Stop
Sets the data rate in bits per second (baud) for serial data transmission. For communicating with Serial Monitor, make sure to use one of the baud rates listed in the menu at the bottom right corner of its screen. You can, however, specify other rates - for example, to communicate over pins 0 and 1 with a component that requires a particular baud rate.
An optional second argument configures the data, parity, and stop bits. The default is 8 data bits, no parity, one stop bit.
