@SergeP I especially like the MQTT idea, but can this run also on a windows10 machine in case I have to use one? as far as I understood it, MQTT messages are converted not on the Puck.js but afterwards, when the advertised sensor data arrive at the client
@kri100s thanks for the links, I suppose I could first make a quick&dirty test with my Samsung Galaxy S8 as well, without ordering a Puck.js?
Followup general question:
Any idea how to implement a good reliable distance measuring (0.5-4m / resolution min. 5cm steps)? I am just looking into the "Grove Ultrasonic Sensor", but an all-in-one solution, maybe with the Puck.js and Bluetooth I wasn't able to find up to now (because all online sources state that Bluetooth distance measuring is quite unreliable) would be much preferable.
Yes, you could test it with your phone first.
@Gordon suggested laser sensors which would be my choice too.
I am wondering what do you want to use the ranging for. From your initial project description I suspect you are trying to not only get rotation/inclination but also translation (moving in line)? If thats true I think this project might be more challenging. You get into stuff like SLAM and sensor fusion.
