Recently I bought Ecotech Vectra S2 pump. Pump work itself with QuietDrive, no problem.
When I try to connect it to Mobius, all went well up to where you can set-up constant speed (using as a return pump). But after setting up the speed I was unable to "Resume" Tried few times changing the speed setting but same result. Then I restart the app. Now it's not connecting to the device (pump, QuietDrive).
Try with a different mobile but same result.
