Hi @lxaiia ,
The reason why older versions are not shared is because MEMS Studio is an evaluation tool to test device functionality before customers purchase samples for their final products. This tool is closely linked to supported board firmware versions, so it should always be aligned with the latest firmware to avoid unexpected behaviors.
For this kind of requested, you need to open a ticket to the online support system, which will evaluate your request and share the tool version if appropriate.
