i am Sorry, yes, the version is 2.7.0. The question is how do I mitigate the use, my classroom has 45 students?
I currently use the application, but the devices it supports are 10, the others fail to load the content and others just can not connect to the device, in some forums said that removing the password improved performance a little.
I have read here that one of the causes is the source of power, and that I must visualize the flicker of my raspberry, but it has worked very well without any energy slumps.
The device I use is a raspberry pi 3 B +
