My 100/30 system (2x200 w 42v in parallel) was working well, and victron connect via usb was also good. Then the phone died and I bought a new one: Samsung J2 pro running Android 7.1.1.
Attempted to connect, was told of need to update from v 2.12 to v 2.14. Attempted to do so, got a fail at 1%, repeatedly. Fooled around with various things, and at one point actually got it to go to 60% before failing. More repetitions and it did indeed say it succeeded, and showed that it was now v 2.14. Hooray! But, upon trying to connect, it again said that it needed to update, and further attempts have led to it repeatedly failing at 1 %, with failure codes #4 usually and #8 once. The manual says that this indicates that it is unable to connect with the MPPT bluetooth, but does not suggest a fix. Distance between phone and MPPT is less than a meter. I have disconnected the unit from all power several times, leaving for five or more minutes with no change noted.
In addition, a second phone (Moto C, Android 7.0) which had the app loaded and running well now fails to connect, stopping at 60% and recycling back to 20% endlessly.
The system is still working as far as I can tell, but I have no means of monitoring progress or charge state, nor changing charge parameters. I'm out cruising, using the solar system as our main source of energy and am loathe to send the unit in for service. It was purchased from Solar On Line in Australia, and I am currently cruising in Tasmania.
I could use some help!
