So I have a project that has a remote Arduino with 3 sensors attached and an Xbee s2c connect to my computer with a usb. In XCTU the sensor data is all correctly received but when I open the Arduino serial monitor there are weird characters right before every line of data. I think it may be the start delimiter, length, frame type, 64-bit source address, and 16-bit source address. The weird characters are the exact same before every data point. Is there any way to fix this?
