Hi,
we would need further details. How are you attempting to connect? Have you previously done so successfully? Have you looked through the getting started material?
Note : part of the chronos does not contain an msp430 and can therefore not be programmed with CCS. The watch does have an msp430 and can be programmed with the windows version of CCS as per the user material.
