Hi, You can choose to never release the RRC connection from the Config menu. Or you can choose a longer "inactivity timer" before the connection is released.

Here from the CMW500 Help:

Hi,

When I load the configuration file into CMW500 and run the testing again, the connection between DUT and CMW500 can be last for longer time for making Tx / Rx measurement but RRC connection is still released for a while (like this).

I need to restart the DUT to make further testing. Is there any suggestion on the UL/ DL setting that I can keep RRC connection for a bit longer time for more testing?

Hi, can you try to load the following NB-IoT signaling configuration file:

devzone.nordicsemi.com/.../4505.DAU_2D00_NB1_2D00_M1.dfl

Also try to set the connection pattern to Alternating UL/DL.
