Hi I have a 500AH Smart Shunt, all was working well until i switched from the MACbook to the iPhone app i pressed disable bluetooth thought it was the computers bluetooth turns out it was the shunts bluetooth. Now its totally disabled and i cant turn it back on. I have the PUK as its on the label i removed the shunt from power let it sit for 5 mins and put it back in still no joy. So question is how does someone turn the Bluetooth back on i dont have the cable or and other victron device.
