Hi Everyone!
We have noticed some room for growing the pool of WiFi-enabled platforms
in IoTivity. During our prototyping activity, we decided to port ESP8266!
I have included some photos, to let you know how it looks like. You can
find the at the end of this e-mail.
* The small chip is ESP8266-12 itself.
* The small device is just an ESP8266 with power input and some pins
to reprogram it. We use it for ex. proxy'ing non-IoTivity devices to
IoTivity.
* The big one is a motion detector, which can be seen in work on the
nearby photo.
It was developed using ESP8266 port to Arduino
<https://github.com/esp8266/Arduino/>, so almost all the code written
for Arduino can be easily reused with ESP8266.
For the technical minded, here are ESP8266 parameters. Please note there
are various variants, so we chose one of the most common options
(ESP8266-12)
CPU Speed Flash Memory size Instruction RAM size Data RAM size
Number of GPIO ports Dimensions Price
80MHz 512kB 32kB 80kB 9 24mm * 16mm about $3
It has some other nice features, such as
* The option of being either an Access Point or WiFi Station (or even
both at once!).
* HTTP Server functionality
* DNS/mDNS support, which means it will automatically appear in a
network with a nice hostname, instead of having to enter the IP address
* EEPROM memory, as well as a File System
* Support for the most common communication protocols, such as I2C,
SPI, Serial
* Interrupts via GPIO pins
* ADC pin
If you have any questions, please contact me.
