I am very interested in the mesh flood example (Day 49 in the 100 projects/100 days) for a project I am working on, indeed it is almost exactly what I need.
What I want to do is make one of the PSOC BLE's a controller who's only role is to send our the RGB data at the push of a button. I am looking at modifying the existing mesh flood example code, and hopefully simplifying it greatly. I am new to BLE, and it is wildly more complicated than the BT serial links I am used to dealing with.
Where do I start with this? Do I need to modify the custom profile? Are any of the examples similar to what I am trying to do?
I saw Cypress had a demo at CES that was very similar to what I am looking for with a proximity sensor controlling light bulbs that were in a mesh - does this code exist somewhere?
Yes, using custom profile would be good for your application. You can refer to this Application Note:
AN91162 - Creating a BLE Custom Profile (http://www.cypress.com/documentation/application-notes/an91162-creating-ble-custom-profile)
The demo shown at CES was based on Smart Mesh which is a new spec by Bluetooth SIG. This is still under development.
