I messed about with the Lora Development Utility from MicroChip on a Linux box today (as I’m not really familiar with Windows anymore). My advice… don’t bother. It’s a 32 bits program, trying to run on a 64 bits machine. It does not detect any serial ports. It is crap…
So… still one dead Marvin, on Marvin at 1.0.1, a power hungry The Things Node… and a few unused TTN Uno’s…
