Thanks, Radomir. Do you have the URL for the MicroPython port ?

I found that device too after I had posted the RN1723 email
below when trying to find related things on Amazon. There is
a *lot* of information available for it on the net and it only
costs EUR 3 or so when shipped from China. The major advantage
I see is that it plugs directly into the breadboard without
any soldering.

The interfacing is not as easy as for the RN1723, though,
which uses clear text commands, whereas the ESP8266 uses
cryptic AT commands.

I guess I'll give the ESP8266 a try first and then fall back
to the RN1723.
