Strange. I cant get those bars/number to update at all. I connected while mooshimeter was touching my phone and got 4/4 and 80. I went to other side of the house, where updates seemed to slow down and waited for a minute and it still had same signal indication on the screen :D
Disconnecting and rescanning do update signal strength on device list, but it seems that we cant get any info while connected. At least my mooshimeters seem to work just fine, but signal strength would be nice to see. I have no idea if that has worked in the past.
Do you still get reasonable range for your device? It says 50 meter of air with line of sight on specs, but i’m quite sure that would not be that stable to be usable. I have been positively surprised at about 20 meters though.
