I have a problem with realtime reading when I try to have the right reading for 1 second I get 68 mb which is not correct but I get the right values when I click on 5 seconds ?
is there any solution and can anyone tell me what is the reason for this ?
This is a limitation with your device. Devices cannot return data that quickly. The mostly likely frequency to work is 10s in my experience. (5s works on most devices, but not all)
