I am developing IAS-CIE & IAS-ACE on TWR-KW24D512 & TWR-KW21D256. After the ACE get the successful Enroll-Rsp message, I press the SW1 on TWR-KW21D256. Unfortunately the ACE can't send Arm command to CIE over the air. Could you tell me why the ACE can't send Arm command.
It seems you have not change the application to Run mode (long SW1 press). Once in run mode, SW1 key press will send an Arm command to the central equipment for all zones. After receiving the enroll response, the device is still in configuration mode. Please long-press SW1 until only LED D7 is ON. I just tested and it worked without problems.
