CC1312R: Building Light Management System with CC1312R + Gateway (Development concept questions)

Jay Kim
Intellectual 475 points
Part Number: CC1312R
Other Parts Discussed in Thread: TIDEP0084, SIMPLELINK-CC13X2-26X2-SDK
Hello,

I'm now study making building light management system using TI 15.4 stack / CC1312R
and have several questions.
We're about to deploy 1,000~2,000 Sensors to each building(basement parking lot)
<Reference>
(1) TIDEP0084
(2) SimpleLink CC13x2 26X2 SDK -> TI 15.4 Stack -> Collector/Coprocessor/Sensor
<Products>
(1) Sensor : Building light controller with motion sensing capability.
         When motion detected, each Sensor turn on light which connected and send turn-on-light command
         to Sensors in same group.(each group consist of 6~8 Sensors and intended to do same turn-on/turn-off actions)
(2) Collector : Receive status data from Sensors and toss it to Gateway.
         Receive configure data from Gateway and toss it to Sensors.
(3) Gateway : Which has ethernet connection to Management PC program or Cloud.
         communicate with Collectors.
(4) Management PC Program : Manage Sensors. (watch sensor's operation status and configure... etc)

<Question>
1. When using TI 15.4 stack. Eash Sensor can send Sub-Ghz message to other Sensors directly?
   (for example, turn-on-light command to other Sensor in same group)
   or Collector(or Management PC Program) have to do this?  
2. If Collector goes malfuntional, Sensors which joined network by that Collector also removed from network?
3. What is exact difference between Collector and Gateway?
   (In TIDEP0084, Gateway doing Collector role?)
   And if I don't need remote management, only Sensor&Collector combination can make system?
4. Any other references I need to study?
Regards,
Jay

    Hello Jay,

    First, I would recommend that you reference the latest TI-15.4-STACK-GATEWAY-LINUX-SDK solution and SIMPLELINK-CC13X2-26X2-SDK documentation if not done so already: https://dev.ti.com/tirex/explore/node?node=APeHcG.A0wniaym22zAYKw__pTTHBmu__LATEST 

    1. No, in a star network each sensor child node must report directly to the collector parent.
    2. End nodes which receive repeated communication failures may choose to become orphaned and re-align with the coordinator or disassociate and find and new network.
    3. A collector controls the application from a single device, whereas gateways utilize a host processor to maintain the application and communicate commands to a MAC Coprocessor.  Either solution is capable of maintaining a network.
    4. The 15.4-Stack User's Guide will answer most of your questions.

    Regards,
    Ryan
