Hi,

Have you had any progress with this?

Hi,

Any idea on how to solve this?

I just added these lines of code under if(button_number ==3)

uint32_t status2 = temp_status_publish(&m_light_lightness_server_0);
              if ( status2 != NRF_SUCCESS)
           {
            __LOG(LOG_SRC_APP, LOG_LEVEL_WARN, "Unable to publish status message, status: %d\n", status2);
           }

In the J-link it does not print any error, hence, I am assuming it is publishing correctly.

I suspect that you are not sending the values correctly. Looking at the "if(button_number == 3)" in the code above it looks like you aren't publishing anything to the client when button 3 is pressed. It only reads out the temperature and humidity.

This is the log on the server side. Whenever I enter '3', an update of temperature and humidity will be shown. I am not sure if its being sent to client side.

Can you check on the server side what temperature value that are being sent? Is it sent at all?

Hi, thanks for the reply

No, I am not able to receive the data on client side. The temperature reading shows 0

I am using SDK 17.0.2, mesh v4.20

Also, this is the log that appears in the J-link

00> <t:     583150>, main-poll-4bytes-8lights-level.c,  482, Sending msg: Ack Lightness Set: Lightness: 65500 Tid: 2 Trans time: 0 ms Delay: 0 ms
00> <t:     585328>, main-poll-4bytes-8lights-level.c,  201, Acknowledged transfer success.
00> <t:     585331>, main-poll-4bytes-8lights-level.c,  231, Lightness client: 0x0231, Present lightness: 22, Temperature: 0

Hence, in the if/else statement, the log is showing the else portion as temperature is added to that log as well. The problem is that the client side isn't receiving any data about temperature from the server.

Hi,

Are you receiving any data on client side when you try to send the temperature?

Also which SDK version are you using?

if (p_in->remaining_time_ms > 0)
    {
        __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Lightness client: 0x%04x, Present Lightness: %d, Target Lightness: %d, Remaining Time: %d ms\n",
              p_meta->src.value, p_in->present_lightness, p_in->target_lightness, p_in->remaining_time_ms);
    }
    else
    {
        __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Lightness client: 0x%04x, Present lightness: %d, Temperature: %d\n",
              p_meta->src.value, p_in->present_lightness, p_in->temp_read); //just added temp_read to read temperature values from server
    }

Also this code snippet on client, won't this if statement prevent the client from ever reading the temp value if the if statement is true? Can you check if this is the case?
