Bluetooth Mesh Light CTL (color tuned light) sample

[ji_584]

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

I see.

Could you try debugging and figure out where it fails, and exactly what is returning  bt_mesh_adv_ext: Advertising failed: err -12?

Call stack when the error occurs:

The error seems to arise here:

In bt_hci_cmd_send_sync()

(/home/user/ncs/v2.8.0/zephyr/subsys/bluetooth/host/hci_core.c:440)

...

case BT_HCI_ERR_INSUFFICIENT_RESOURCES:

return -ENOMEM; (-12)

When there a command

This error code gets returned back up the chain to:

In bt_le_ext_adv_start()

(/home/user/ncs/v2.8.0/zephyr/subsys/bluetooth/host/adv.c:1657)

The error is printed:

...

err = bt_le_adv_set_enable_ext(adv, true, param);

if (err) {

LOG_ERR("Failed to start advertiser");

if (IS_ENABLED(CONFIG_BT_PERIPHERAL) && conn) {

bt_conn_set_state(conn, BT_CONN_DISCONNECTED);

bt_conn_unref(conn);

}

return err;

}

I guess it's something down in the Bluetooth controller.

I tried to turn on some logging and am getting

[00:08:20.424,499] <wrn> bt_hci_core: opcode 0x2039 status 0x0d

[00:08:20.424,560] <err> bt_adv: Failed to start advertiser

[00:08:20.424,591] <err> bt_mesh_adv_ext: Advertising failed: err -12

I think status 0x0d is BT_HCI_ERR_INSUFFICIENT_RESOURCES above, so that's at least consistent.

Could you send me the .config file you get generated for the build?

By the way, I previously said the error wasn't catastrophic, however, today when I try the issue again, it does sometimes crash after several seconds.

There was one .config in project\build\zephyr and one in project\build\project\, both are included.
