Relay of MESH SDK V2.2.0

[sophieyellow]

Hi,

When I go through the code of light switch example, I am confused about relay functionality.

Compare with the v2.1.1, I can find the m_relay_enable in network.c but in v2.2.0 couldn't. So in this version, how could I enable and disable the relay function?

I know people has asked similar question before but I still don't quite understand. Thank you very much for your help.

This devzone case should be helpful.

When I trace through the code, I still don't understand that where I should modify the code or what function should be called.

Sorry I am a beginner to this SDK, please help. Thank you.

Take a look at the handle_config_relay_set() function. The bool enabled is set here: .params.relay_set.enabled = (p_pdu->relay_state == CONFIG_RELAY_STATE_SUPPORTED_ENABLED)

Hi, 

I checked the function and it looks exactly like what you stated above, however, is there any way to check by using log that the node is relaying? I set a log function to the function you meationed above like this: 

    const config_server_evt_t evt = {
        .type = CONFIG_SERVER_EVT_RELAY_SET,
        .params.relay_set.enabled = (p_pdu->relay_state == CONFIG_RELAY_STATE_SUPPORTED_ENABLED),
        .params.relay_set.retransmit_count = p_pdu->relay_retransmit_count,
        .params.relay_set.interval_steps = p_pdu->relay_retransmit_interval_steps
    };
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "config_server_evt_t relay = %d\n", evt.params.relay_set.enabled);

But nothing appear in the log viewer. I dont know why.

It won't work to put a log message where you have put it. What if you try to check the relay state of the p_pdu->relay_state function instead after e.g. this line in the handle_config_relay_set() in config_server.c:

relay_state.enabled = (p_pdu->relay_state == CONFIG_RELAY_STATE_SUPPORTED_ENABLED);
