| 説明 | Herewith the results with Pybricks Python.I tested the 4 possibilities:RI - RI hubRI - Technic hubTechnic hub - RI hubTechnic hub - Technic hub.The results were really surprising.First, let's take the version Technic hub - Technic hub.This was not so good. The variation in delays are very large. Sometimes it is fast down to 15ms other times it can be very long to over 300ms. All tests were done with the program running in the hub and the online web version disabled. You can now also clearly see the LED 3x3 matrix data on ch-A of the picoscope and the 2 x consecutive output as a reference position where there is a change in the Bluetooth data.You can see the measurement setup in the photo: www.flickr.com/photos/fotoopa_hs/52709854066/in/dateposte...The next option was with an RI hub and a technic hub. The results were the same for:RI - TechnicorTechnic - RIAgain the times could vary quite a bit but the max time was still quite low though, around the 65 ms while there were also very low times as low as 1 ms. Over several measurements the average value was around 30 ms. This is already a very good result. As soon as one of the hubs is an RI hub it becomes very reliable and the values are quite good.Now the RI-RI version:This combination works perfect. The max times are arround 6 ms, most of them just above the 2 ms, minimum 1 ms. The results are also very stable. You can see a total overview of a measurement above. |
