In a project where I thought I had TSU9600 with router communication issues, it might have been the RFX9600 at fault all along.

I have TSU9600 (7.2.22) communicate with RFX9600 (1.4.5) and when sending simple 1 or 2 step command to the RFX9600, the function seems to execute fine once, but if I try to press the same function the second time within 1-2 seconds, the Busy light comes on (no function is sent or seen from RFX9600 to device), and stays on for 20-25seconds.
During that time, no other functions can be sent to RFX9600.

BTW, the are no ProntoScripts or 2 way communication being utilized on this project.

Anyone had this issue, and knows how to handle it?
