Hi Robin2.
Ok, Victron Is a solar power supply manufacturer, so they supply invertors (and more) and solar charge controllers known as MPPT's or Multi Power Point Trackers they take the power generated by your solar panels and in turn charge the batteries in the most effective way possible, the MPPT give info on its UART port that tells you what power is coming from your panels and what is going to the batteries, a BMV a Battery Monitoring Voltmeter, it's UART port gives battery stats, normally to read these devices into the software you need two separet UART to USB dongles, problem with laptops is the lacking number of USB ports that they have, what I would like to do is use one usb port to monitor both these devices in turn, it saves a USB port and the extra 800 bucks for yet another dongle, the other thing is that the software can only monitor one device at a time anyway. So, using Software.Serial seems like right way to go, the role then of the Arduino is to replace the 2 dongles with just the Arduino. I just don't want to unplug and replug on the Arduino as that would mess up its contacts anyway after a bit....
Ps. Allot of Victrons stuff is made open source so they give people the opertunaty to come up with alternative means of monitoring and interfacing with their products it must just be kept open source..
Thanks for hearing me out....
I appreciate it.....
Kind Regards.
