I am using power supply module on 5V jumper to power LCD and Nano. In both cases, I upload code to Nano via USB but then in both cases, am not using USB for power. Literally just upload code from IDE via USB, then remove USB and plug in Nano to breadboard / power supply, works. Upload code via Cloud, then remove USB, plug in Nano to breadboard / power supply, resets.
I do have other IoT / Cloud code working fine with dashboards et al, just something wrong with my LCD setup??
