How to Recive API Frames on Connect port X2

Can someone help us out. We have a Connect Port X2 here. XbeeHP 900 type.

I have sent a frame from the connect port to XCTU no issues. Now we are trying to send a frame to the X2 and have it print this frame.

Send a frame to the X2 and have it print the frame out.

Test #3
send this data to MQTT

Everyone here is having a really hard time trying to decipher the help documents and all the dead links.

I really would like to get this working. Its part of a project test for a large global mining company. We are almost at the point of sending this gateway back to Digi.
