Thank you for your note, I modify the sensitivity and other parameters to leave them adjusted to the optimal performance I want, the problem is while you operate in the laboratory, this event that I mentioned is repeated. The problem is that if you have "many" eye sensors together in the lab, the APP stops seeing some of them and if you don't empty the cache and storage data of the APP and force it to stop, it doesn't recover the vision of those BLE. Then when you start and ask for "GPS location" as if it had just been "born" it already operates normally for one or two hours. I have to do it often in a work session to keep seeing them with EYE APP.
