I want to design robotic cars that have a persistent connection to a PC on the same wireless network. The PC will feed the cars with control data (speed, turning, horn, etc.) in real-time, acting as the controller. This data will be sent as a String of consistent length (something less than 32 bytes) as often as possible.
I assume this is not a job for Cloud functions. How would the Photon or newer Particle boards best accomplish this?
