There is quite a lot happening with the ESP8266 on this front. These low
cost wifi are powered by an advanced mcu/SoC running at 85mhz with a
full tcpip stack. They are very powerful little microcontrollers in
their own right with @12 gpio's available.
There is a new development toolchain called Sming that is worth a look.
It is an Eclipse based Arduino IDE, using normal Arduino code to program
the ESP8266 Tensilica chip. These boards have been hard to use, mainly
because the tools/compiler for these new mini-SoC chips. Sming looks
promising. Finally something useable which compiles compact enough code
to fit on these little boards.
The ESP8266 looks like the leading technology for the whole IoT
movement. Sming, I understand, will soon have full MQTT support as well
which is a lightweight messaging protocol that piggybacks on tcpip. MQTT
is looks to be, currently, the de-facto IoT standard protocol.
/"MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity
protocol. It was designed as an extremely lightweight publish/subscribe
messaging transport. It is useful for connections with remote locations
where a small code footprint is required and/or network bandwidth is at
a premium. "
/Of coarse, a full Oberon based "Oberonnet of things" is most
interesting too. The new Oberon soft core processor Chris Burrows is
working on for Astrobe should be able to fit nicely on an Ice40
miniature form factor FPGA. It will enable us to fit Oberon onto a 4mm x
4mm chip that costs < $7. A purely native SCC.Mod based "Iot mini board"
sure would be nice, huh? Instead of the Nrf24l01 have an ICE40 FPGA
board (plus oscillator, components necessary) run the network/IoT on
this dedicated "Oberon soft core". At 4mm x 4mm it could be even smaller
than the Nrf24l01.
We do need a way to interface to the standard IoT world. The ESP8266
will give us a good bridge to communicate with the outside.
