Brand new SmartShunt 500A/50mV. Most things seems to work with the VictronConnect app on my LG phone. Except when I go to the settings menu, it tells me I must update before I can do settings. When I update it always fails at 2%. After couple of seconds it gives me a D26 error code. I need to power cycle (via the fuse) the PowerShunt to get Bluetooth connection back. I tried a 4 inch and 2 feet distance between my phone and the SmartShunt, it all got stuck at 2%. I tried bluetooth unpairing and resetting my bluetooth pin code. Nothing seems to work.
Anyone any idea what it can be? (before I send it back).
P.S. I'm already using my VictronConnect app with my SmartSolar SCC. I have done multiple successful firmware updates with that app for that device.
