'if you have a tablet, that most likely has BLE too'
Answered that in second sentence in post #17 Three year old device recognizes PC but doesn't recognize BLE devices.
'AFAIK, you don't need a SIM card to use wifi'
Isn't the SIM card integral in allowing/exposing the MAC address in order to comm with other devices via any means? I was under the impression that mfg's protected their products this way.

Hey, if you have a tablet, that most likely has BLE too.
AFAIK, you don't need a SIM card to use wifi at all. You can use your wifi connection to perform all the smartphone-y things like installing apps from app-store and download emails.
