Yes... Now i have get the program to work very well whit inverted mode, tested it at 100 meters and there no errors or missing numbers.

But then we come to the next problem, I have searched the forum and I find out that i´m not alone whit this problem, but the solution for it does´t work for me.

I can´t get the SERIN timeout to work, and yes the input is switching between high and low when the transmitter is off. i have tryed whit an 1K, 3K, 4.7K, 10K resistor between GND and the input pin but when the timeout works the recive module does not and when the reciver work the timeout does not.

So what else can i do? is there an software solution for this or must i use an hardware solution?
