I’m just double checking before I implement.  
I assume my Photon TCPSserver connects and communicates with my iPhone TCP client ONLY through my local access point, and DOES NOT go through the Particle cloud.

@douglaskbell, your TCPServer opens a TCP port on your photon which your iPhone can communicate with through the internet or your local LAN and does not involve the Particle cloud. 😀
