I've had a MPPT installed in my ute for the last 2 years to connect the panel for lights, fridge etc when camping. I just hooked up the panel & fridge to make sure everything was working prior to an up coming trip when a notification came up to update the software which I did. The unit no longer bluetooths to my phone. It is shown on the bluetooth connections page in the settings menu on the phone as being available but when I open the screen to input the pin (000000) it connects, the connection get to about 80% then it goes to the pin input again. Looking at the LEDs on the unit it appears to be charging ( solid blue) & when disconnected the light is blinking. I'm hoping its a straight forward reset thing but I'm no computer/ phone/ electronics guru so if I get any replies assume your talking to a bit of a techo monkey! Thanks
