### 2/5 — Works when it wants to

*2025-12-30*

Sometimes it’ll connect to the device, but most of the time it doesn’t with client mode. Need to release an update for more consistent performance. Besides that it’s really cool when all is working.

### 2/5 — Event Mode doesn’t work

*2021-03-26*

I have no idea how this version got released.  Kessler is aware of it but hasn’t put out an update yet.  The real kicker is this is a paid upgrade to KOS.
