The below table shows the firmware compatibility of the BMXP342020 across different versions of Control Expert/Unity Pro. Please note that the application version refers to the version of the firmware selected with Control Expert/Unity Pro itself rather than the actual firmware within the physical device. However, if you upgrade the firmware of the device beyond the supported application version, it is still possible to use it in Control Expert/Unity Pro, albeit with some limitations, assuming the old (and supported) application version is maintained. For example, in the below matrix you can see that the maximum supported application version for Unity Pro V6.0 is V2.3. However, if the firmware is upgraded from V2.30 to V2.40, it is still possible to use the CPU as long as the application version is maintained at V2.30.
