Yes the code examples work as does my preview set up. I'm just simply missing something in writing the new receiver code.

Take a look at the code that I shared, this is the minimum required code for a PTX and PRX with ACK, once you have verified that works it is easier to move to your specific configuration.

wow, simple issue... My dataready was missing the CE high. I forgot that needs to be held high to receive. but now its not Ack'ing back like it does when the arduino talks to it. So I'm still missing something,

for my receiver I do this.

        ATT_ON(); //forces all commands to send right away, puts device in receiver mode.
       enable();//set ACK payload
       sendCommand(0xA8);sendCommand(0x0A);
       disable();
but my transmitter device never receives the ack. As soon as I plug in the ardunio receiver and run my code the ardunio gets an ack back. So know my auto acking is all set up correctly on the transmitter end. The receiver code is the same as the transmitter code except for the PTX and code I put above. Is there another bit I need to set other then the 0x00 register ( 0: PTX ) mode and leaving CE high? The transmitter sends data, my receiver receives it and I can read the correct data in the buffer but it never acks back.

Maybe you can look at this case that describe the minimum configuration required for a PRX and PTX:
