I send this string lFinalSentString = "Hellog this is a long text to see if ti can receive a loooooooong text FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF";
Serial2.println(lFinalSentString);
and I receive half of it almost........ from aduino MEGA I really don't know what to do,
The wiring is that the esp 32 is connected to the arduino with wires TX RX and GND, each other idk iif it is 5v or 3.3v or... no idea.....
do I even need resistors? \
If I send a short string it works.... like "hello"
help
