Frame Size Modification of Zynq AD9361's QPSK models

Excuse me,
I'm working in a project related to design a communication system based on QPSK modulation. New I'm Using the "QPSK Receiver Using Analog Devices AD9361/AD9364" and "QPSK Transmitter Using Analog Devices AD9361/AD9364".
I'm wondering to change the data frame size in the model. Could you tell me how to modify the frame size correctly?

For the transmitter, the frame size is controlled by the dimensions of the data sent to the data input port on the block.
For the receiver, this is controlled by the "Samples per frame" property on the block - see the documentation here: https://www.mathworks.com/help/supportpkg/xilinxzynqbasedradio/ug/ad936xreceiver.html

I need some more information to understand why the data would not be decoding.
- What frame size have you configured the models with? Do both the transmit & receive frame sizes match?
- How did you configure the frame size for the transmitter model? Did you change the value of the buffer feeding the transmitter input?

Martin
