Hey Renzo,
I’ve tried several different wires and I have always used an external power supply. The E220 always works with my uart to usb connector whatever the wires I use. The problem is somewhere else.
Anyway, i’ve done what a lot of people who have this problem to avoid wasting my time, changed to a better more reliable lora module.
Have a good day.
