Hi there,
I was wondering if someone at Nordic could verify something for me. I had a go at modifying the lightswitch example (node_setup.c) in the mesh sdk, to instead be setup in this configuration: One "Client" to many "Servers". I currently have it set up so that I can send a "trigger" packet from my client node to either of my four server nodes (which sample sensor data). This will then start an app timer on the device in question which then pushes its sensor data to the client at every time interval. This setup is similar to the Thingy52 mesh demo which is based on the older mesh sdk (v1.0.0).
What I would like to know is:
1. For my client and four server nodes, is this the correct way to set up the provisioning:

2. I wish provision more than four server nodes, and have them behave in the same way. How do I modify my existing code in order to add more nodes? Do I do this:
/* Sequence of steps for the client nodes */
static const config_steps_t client_config_steps[] =
{
NODE_SETUP_CONFIG_COMPOSITION_GET,
NODE_SETUP_CONFIG_APPKEY_ADD,
NODE_SETUP_CONFIG_APPKEY_BIND_HEALTH,
NODE_SETUP_CONFIG_PUBLICATION_HEALTH,
NODE_SETUP_CONFIG_APPKEY_BIND_ONOFF_CLIENT,
NODE_SETUP_CONFIG_APPKEY_BIND_ONOFF_CLIENT,
NODE_SETUP_CONFIG_APPKEY_BIND_ONOFF_CLIENT,
NODE_SETUP_CONFIG_APPKEY_BIND_ONOFF_CLIENT,
NODE_SETUP_CONFIG_APPKEY_BIND_ONOFF_CLIENT, //added
NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT1,
NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT2,
NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT3,
NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT4,
NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT5, //added etc
NODE_SETUP_DONE
};
And add the corresponding case statements in config_step_execute()? Is there anything else I need to adjust in other files?
3. Rather than setting up multiple client model instances in that fashion, could I maybe just have one, and have all nodes in the mesh subscribe/post their data to that model? Is my understanding correct?
4. I want to know how to correctly set up grouping so that I can have one sever group in which I can send one "trigger" packet which all nodes on the mesh will then receive and subsequently start pushing their data.
5. With my current working setup of one client and four server nodes, every now and then one or two nodes will stop pushing data. (the sensor data update rate is the same on each node ~3 secs). I suspect something is causing these nodes to reset (mcu could be hitting fault). Is this because I am trying to send too much data at once around the mesh? My packet size is 20bytes. In the function simple_on_off_server_status_publish() there is a field called msg.force_segmented = false, could I use this to get around this issue? As I understand the maximum reliable packet size is 15 bytes (read something along those lines on the forums).
I made a previous thread on some of these problems (which I have sorted, as I have four server nodes "working" to some extent), but did not get an official reply -> devzone.nordicsemi.com/.../light-switch-example-modification-using-nrf-sdk-for-mesh-2-0-1
If you could please help me out that would be greatly appreciated.
