We have the one that we have, and it is typical of smaller devices.  And we aren’t able to change horses now for the valves or for Launchpad.

We are likely to have to stay low-end to keep costs down for both projects.

But in any case the issue is more to do with a combination of common radio module behaviour and interrupt latency; an otherwise more powerful MCU could even be worse.
