Would like to add to the exosite IoT dashboard with Connected Launchpad

Hi Viking,

1. Buildable source for the demo that came with the Launchpad. Where can I find that.

The Tiva C Series firmware install includes the code that came on the LaunchPad (qs_iot is name of project).  There is also another project called 'senshub_iot' I believe that also works with Exosite.  I've posted instructions on how to use that one here:  https://github.com/exosite-garage/clp_sensorhub_support

2. Protocol for data transfer between exosite and Launchpad. Maybe this is wrapped up in nice API calls?

The Connected LaunchPad uses the Exosite API, specifically the HTTP DATA API which uses standard HTTP POST and GET methods to read and write data.  In the qs_iot project, you'll see an 'exosite' library in 'third_party' folder.  There, the functions put together the proper strings to send the HTTP packet of the socket.

https://github.com/exosite/docs/tree/master/data

For example, a get request ends up looking like this, although there is a function all that does this for you, you just call 'Exosite_Read' with your parameters.

// This is an example read GET
//  s.send('GET /onep:v1/stack/alias?temp HTTP/1.1\r\n')
//  s.send('Host: m2.exosite.com\r\n')
//  s.send('X-Exosite-CIK: 5046454a9a1666c3acfae63bc854ec1367167815\r\n')
//  s.send('Accept: application/x-www-form-urlencoded; charset=utf-8\r\n\r\n')

The POST and GET methods support sending/receiving multiple dataports at a time.  You'll see in the code where 'Exosite_Read' is called and how it passes multiple parameters to be read.  Note that the Exosite library also includes the activation calls, to the Exosite provision API.

3. Tutorial on using exosite. Any limits on building dashboard with the exocite licence given through TI?

There are not many limits on the Exosite TI portal (ti.exosite.com).  You can build a few custom dashboards which includes adding your own custom widgets if you want.  You can add more dataports to each device (client in Exosite platform), there is a soft limit of 50 included with each added device for a total of 100 to use with the two included devices in the free account.  You can add cloud scripts (written in Lua) to each device, again there is no hard limit on this.

You may want to start here for using Exosite Portals: https://support.exosite.com/hc/en-us/sections/200072708-User-Guide

Scripts are covered here: https://support.exosite.com/hc/en-us/articles/200513440-Scripting

All of the Exosite APIs (device, provisioning, cloud scripting, custom widgets, etc) can be found here:  https://github.com/exosite/docs

Example Scripts: https://github.com/exosite-garage/PlatformScripts

Example Widgets: https://github.com/exosite-garage/custom_widget_scripts 

I hope this helps!
