Hi there, I'm running ~v2.6 Venus OS on my Raspberry Pi 3b with wired USB connections. If I upgrade to 2.70+ will I be able to connect via the onboard bluetooth to Victron devices without the need for wired connections? Also, which file can be used to flash an SD http://updates.victronenergy.com/feeds/venus/release/images/raspberrypi2/?C=M;O=D? Thanks very much!
