Originally had a BMV-702 which has old firmware on it. Was using it to monitor my trailer battery SOC. Now purchased a Victron MPPT 75/15 Smartsolar charger for the trailer battery. Trying to figure out the best way to 1) get my BMV-702 updated and 2) connect the two devices so they share data.
Can I connect the BMV-702 to the MPPT 75/15 directly with a VE direct cable and then use the blueooth on the MPPT 75/15 to update the BMV-702?
If they are connected to each other with the VE direct cable (ie not ve direct bluetooth on the bmv-702) will they share info and both show up in the Victron app through the Smartsolars bluetooth?
