Sending a 0-byte data actually does nothing on PacketSerial (returns directly in the send method).
However I find it quite common to send such empty data. For example, a simple protobuf struct:
message SimpleMessage
{
bool value = 1;
}with its value set to false will be encoded as a 0-byte buffer by nanopb. I guess it's better to just send a PacketMarker for this kind of data.
Expected Behavior
Send a PacketMarker for 0-byte data.
Current Behavior
Does nothing on 0-byte data.
