How can I send RBG data over mesh?

[Farhanah Ruslan]

Based on the demonstration video of Thingy, I can have a view on Thingy is changing its color when it is given different command using the apps. 

1. As if I want to send RBG( Red, blue, green) commands to nRF52832 with development kit of PCA10040 over mesh, is it practical?

2. Or, must I implement UART over mesh to send RBG (Red, Blue, Green) data command? 

Also, from the video of the period 0:47 to 1:00, I saw that it is told "The phone is connected to only 1 node and the node is a gateway, so when I send a command, the command goes to the Gateway and from the Gateway, it goes to all the nodes."

3. Does it show that we can implement 1-to-1 mesh but we may have many devices as output?

4. As I have known, Thingy is also using nRF52832 as well. But, it is shown that Thingy can be used to control the LEDs with different colors. Is there any example code for it? If I used the 'light switch' example in the folder 'nrf5_SDK_for_Mesh_v2.0.1_src', will it work as shown in the video?

Thanks, Edwin. 

Sorry, I am still new to this technology. I have doubts to be solved.

1.Must I use Nordic Thingy to achieve UART over a gateway node to all device connected? But, how do I can implement that without using UART over mesh?

2. For the answer of question 2,if the demo has a sort of UART protocol, so can I do the same process ( control 1 unit to light up any other bluetooth device) by using nRF528xx series. In more precise, it is PCA10040 development kit.

3. For the answer of question 3, how do I link all the extra devices since UART is designed to have 1-to-1 communication? From the answer given, the phone is connected to the gateway node via "regular" BLE. But, in the video, the engineer used 1 gateway node to light up every device connected to the gateway node.

Which technology - microcontrollers in general? radio comms in general? Bluetooth in general? Bluetooth meshing? Nordic specifically ? or what?

It might be easier to tell us what you do have experience with - it helps us to pitch the replies appropriately ...
