Pluto
c.2020
Pluto was a simple android app I created partially to learn Kotlin and mostly to have a simple way to diagnose our hardware at Roam. It’s actually pretty flexible and I’ve adapted it for various projects for debugging embedded systems. It streams data over BLE through a single “state” characteristic that contains all of the fields to be graphed/monitored. If you utilize the MTU parameter of a characteristic you can send quite a lot data per transmission.
