Is there a sample app that uses the Zephyr Light CTL Bluetooth Mesh model? I've tried to add that model to the light_ctrl sample app, but get a crash during configuration so I must be doing something wrong.
The onoff_level_lighting_vnd app claims to support that model but it doesn't seem to be using the Zephyr lighting models.
Thanks
Hi Jack,
I think you are right. There isn't a sample for that model right now. Please let us know the issue you are seeing we can try to take a look.
We have limited capacity in the holidays period but will be back to full staff by beginning of the year.
Thanks, here goes.
I started with the VSCode plugin light_ctrl sample using version 2.8.0 of the toolchain and libraries. Build machines with Windows and Linux tried. Target is nRF52840DK.
The unmodified sample builds, runs, and provisions and functions correctly with the nRF Mesh Android app.
After the modifications below, the code compiles and runs, but during initialization I get an assert showing on the console (see below), and an "Initial Configuration Failed" message from the app.
Note that the assert states that temp srv wasn't properly initialized. On debugging, however, it appeared that the tmp srv model was properly initialized and the light CTL model was not, however I have a low degree of confidence in this assessment.
model_handler.c was modified from the sample as follows:
Add headers
#include <bluetooth/mesh/light_ctrl_srv.h>#include <bluetooth/mesh/light_ctl_srv.h>
Add placeholder handlers
static void temp_srv_set(struct bt_mesh_light_temp_srv *srv, struct bt_mesh_msg_ctx *ctx, const struct bt_mesh_light_temp_set *set, struct bt_mesh_light_temp_status *status){ // Implement setting the temperature on your hardware}
static void temp_srv_get(struct bt_mesh_light_temp_srv *srv, struct bt_mesh_msg_ctx *ctx, struct bt_mesh_light_temp_status *status){ // Implement reading the current temperature state from your hardware
}

BT_MESH_LIGHT_CTL_SRV_INIT(&lightness_srv_handlers, &temp_srv_handlers);Add light ctl and light temp srv models:

Hi Jack,
It seems CONFIG_BT_MESH_LIGHT_TEMP_SRV is missing.
Could you add CONFIG_BT_MESH_LIGHT_TEMP_SRV=y to prj.conf ?
I did, unfortunately I'm still getting the same behavior.
...
CONFIG_BT_MESH_LIGHT_TEMP_SRV=yCONFIG_BT_MESH_LIGHT_CTL_SRV=y
I also commented out this line in model_handler.c because it was unused and seemingly redundant but still no change.
// static struct bt_mesh_light_temp_srv light_temp_srv =
// BT_MESH_LIGHT_TEMP_SRV_INIT(&temp_srv_handlers);
I'm not sure what could be wrong, my suggestion is to take a look at the test sample at \nrf\tests\bluetooth\tester. What I can see in the project is the CTL server is initialized in the model_handler.c

Hung, I've made progress using your suggestion. I took the nrf/tests/bluetooth/tester project model_handler.c file and rused it to replace the light_ctrl example model_handler. I then deleted several models and some tester-dependent code, and updated prj.conf and CMakeLists.txt. The resulting code built, ran, and provisioned, but I don't yet know if it functions. I'm trying to get a less Frankenstein version going now.
Edit - Actually, I'm getting a different error now at the start of provisioning, but no crash.
Thanks,
Jack
