Double acoustic stopwatch and speed of sound

I am a bit unsure if a second characteristic might work. Dominik perhaps needs to elaborates in how far this is easily possible with phyphox-BLE.

Alternatively, there is byte array for output in .phyphox – a bit elaborated conversions floats/bytes/floats though…

At the moment, there is no “native” solution for your problem in our BLE library. This could easily get fixed when the phyphox side is ready by supporting “offset” (it is not scheduled yet).

So, it is either manually implementing a second characteristic taking values in the .ino code or fiddling with byte array. :/
