I only get a solid red light comes on, tired to connect via serial/UART w/ 9600 8n1 settings and get no output via putty for serial. Both are behaving this way, i have tried 5v/3amp and 5v/2.5 amp power sources, as well as the OTG port connected to my usb30 port on my laptop. Only thing that does happen is when I connect OTG to computer USB port, it tries to install drivers.
They were from the kit on amazon, so everything came with it. I tried other SD cards from my rasberry PI as well and same result.
I paid almost 200 for these devices, please help?
