Hi Hung Bui,

Thank you for the tips Hung Bui. My intension is to create my own demo as well. I think I will start anew again with SDK v3.2.0 as you mentioned. Thanks again!

Hi WHui,

My idea is to port the example to SDK v3.2.0. This would require to significantly modify the demo to be able to use with SDK v3.2. And usually it's easier to base the code on one of the example in SDK v3.2 and the add the code for the thingy and models in.

Regarding your issue, i think you hit the memory limit. You need memory in RAM for each of the client you create.

I don't think it's a good idea to create a client for each and every server. You are doing mesh and you can get to hundreds of node. It's easier to create one single client that can handle multiple servers. You can use group address for this. No need to have one client for each server.

Please be aware that we made the project mainly to create a demo. It shouldn't be used to create your own products.

I would strongly suggest you to study our example (light switch for example) to understand the concept of mesh (access layer, model etc) and then port it to run on the thingy.

Hi Hung Bui,

As you can see from the pic in nrf_mesh_config_app.h above, the total number of ACCESS_MODEL_COUNT is 25. If I add one to the number and make ACCESS_MODEL_COUNT becomes 26, the NRF_ERROR_NO_MEM will be gone. I thought the server count is 10, while the number of my new group (Hardware Infos client (group)) should be one? Do you know the reason behind the number?

Hello Hung Bui,

line 331 is line 15 from the codes above:

        ERROR_CHECK(hardware_infos_client_init(&hi_clients[i], i));

So for "mesh_sdk" folder in this project, i should have nrf5_SDK_for_Mesh_v3.2.1_src instead of nrf5_SDK_for_Mesh_v1.0.1_src right?

Hi Whui,

Could you check what is at line 331 ?

Again, this demo is very old. We strongly suggest you to start with current SDK v3.2.0.

SDK v1.0 is not Bluetooth qualified and you would need to do qualification on your own.
