Looking at putting hooking up truck (semi and pickup) trailer lights to an argon and use bluetooth to communicate with a second argon in the truck. Two questions:
Can I get away with a resister voltage divider to read the trailer lights being on / off, or do you think optical isolation is the way to go?
What is the thought on range from argon to argon via bluetooth? Think it will make it 15 feet from the back of a truck into the cab? I see this about range, is that all I need to know? Device OS API - Argon | Reference Documentation | Particle
