Serial Comms - Wookey - 11-22-2016
I am old-fashioned so like to have simple serial comms that I understand rather than this newfangled HTTP/MQTT over wifi and chrome app fanciness. At least to start with.
This does not seem to be documented anywhere, but I've discovered that (once you got the thing initialised with the chrome app (which just seems to be doing serial comms, so presumably we could arrange for this not to be necessary?)) the device sends out data at the configured period at 256400 baud down the serial conneciton. Excellent.

Some of that is fairly obvious. Some less so. Is there a protocol doc I've missed somewhere or would it be helpful if I started one? Is there a wiki or only this forum and the git repos?
RE: Serial Comms - admin - 11-22-2016
Aahhh.. you've done such a research, i hope at least you had fun
yeah.. this is a firmware that i've been developing for the past 2 years
https://github.com/vlast3k/vESPrino-firmware
And also tried to popularize a bit recently in this failed indiegogo
https://github.com/vlast3k/vESPrino-firmware
Just last week i made the necessary changes so that it can be compiled easily by everyone. Next step is fixing the "help" command so that each command dumps a bit more data. Then i need to add more examples and documentaion. And then i try to popularize it in the ESP8266 community.
While there have been other trials for some kind of platform on top of the ESP like - MySensors and ESPEasy - both of them are rather targeted to makers who maintain their own stuff, and not so much about running a product with customers that face bugs and need support. The other thing is the heat management that isn't implemented in neither of them, so you cannot use small enclosures to host the ESP8266 and temperature sensors.
Just give me a couple of weeks and i will start publishing those stuff.
you can also have a look on the Chrome Config tool, which is pure JS, HTML5 and Bootstrap
https://github.com/vlast3k/vAirMonitorConfig
which sends the commands

Hi Vladimir,
did you have a chance to evaluate ESP8266 successor ESP32?
It looks very promising for future use.
Regards,
Ivan
RE: Serial Comms - admin - 11-22-2016
not yet (too many unexpected surprises with the current sensor
)in general i expect that it will take 6-7 months until the firmware support for it is stabilized
in general i plan to base my next board on it, so that there woould be also bluetooth support and battery option
and we will see what else
