How does luminaire performs adaptive dimming based on ambient light?

[John]

Hi,

Test and verify Bluetooth Mesh NLC functionality based on the NCS 3.2.4 and 54L15 by using mesh light ctrl example.

1. Modify the following configurations in the prj.conf of the light ctrl example:
   CONFIG_BT_MESH_LIGHT_CTRL_SRV_TIME_ON=60
   CONFIG_BT_MESH_LIGHT_CTRL_SRV_LVL_ON=32768
   CONFIG_BT_MESH_LIGHT_CTRL_SRV_REG_LUX_ON=700
   Flash the modified example to the 54L15, provision it using the nRF Mesh app, enable OCCUPANCY MODE, and configure the Light LC Server to subscribe to group address 0xC000.

2. Use a Sensor Server to publish an occupancy message to group address 0xC000; the LED on the light ctrl board will be turned on.

3. Use another Sensor Server to publish ambient light messages to group address 0xC000, sending once every 2 seconds with a 25 Lux change each time, but the LED brightness does not change. Change the sending period to 1 second and then 100 milliseconds, but the LED still does not respond.

How to verify that the luminaire performs adaptive dimming based on ambient light?

Hello,

Use another Sensor Server to publish ambient light messages to group address 0xC000, sending once every 2 seconds with a 25 Lux change each time, but the LED brightness does not change. Change the sending period to 1 second and then 100 milliseconds, but the LED still does not respond.

How do you verify it is not responding? The brightness of the LED? Or do you have some logs indicating that it doesn't respond?

Best regards,

Edvin

Hi Edvin,

Yes, I could see the brightness of the LED and the function periodic_led_work() also would output log via UART when the light level changed.

I also used the Sensor Client on another device to subscribe to messages for group address 0xC000, and I can receive the periodically published ambient light messages.

Best regards,

John
