Bob, I will explain more about the communication. I try to find the soluition for the deaf-blind people and myself. We can use PK, PM, PMO, and braille displays to be face-to-face communicator. I mean "deaf-blind communicate with non-deaf-blind people". Reason the deaf-blind can not hear what other says. Deaf-blind can not read writing by other's hand. Deaf-blind can talk in sign language by tactile (touch). So we can use the braille-to-text and text-to-braille communication.
All equipments are requred to use the cable or cord. I HATE it. I found the Brailliant Braille Display is only one can communication with the laptop or desktop via the bluetooth. I do not know about WiFi, yet. My goal to use PK with the bluetooth because I want to be free from the cables. So I could talk with bus driver, communite passenger, grocery clerk, store rep, and else. Did I help you to see the point?
