Jim,
I agree. I use the terms access point and hot spot interchangeably. Android or at least the old 5.0.1 version I'm looking at on these ancient Samsung S4's have the ability to turn the phone into a mobile Hotspot. Allowing sharing and file and data transfer would also have to be turned on. So it sounds promising I just need time to play and confirm how that will pair with TCPUART.
