I have a bluetooth dongle connected to a 50A/75V MPPT blue solar controller. The controller and dongle have both got the latest firmware installed. I am trying to perform a factory reset as my controller is now required to run a 12v system, having previously been used on a 24v system.
Every time I connect, within 5 to 10 seconds it disconnects from the app then automatically reconnects which leaves no time to adjust settings (I have time to scroll to the appropriate setting and press reset but it will not stay connected long enough to perform the reset) . I have tried using three different phones all with the latest version of the app installed. The app/dongle was able to update the firmware on startup so it seems as though it is capable of holding a connection in some regards.
