RSSI MESH example?

[Shahin97]

Hello,

I am looking for an RSSI example, using the dev-kit nRF52DK. To start off, I will have two dev-kits and measuring the range between the two units. After that I would like to have several units, to test an extended range.

First part solved!

I have used the example Light + Light switch and have added the following

in file:  app_onoff.c

static void generic_onoff_state_set_cb(const generic_onoff_server_t * p_self,
                                       const access_message_rx_meta_t * p_meta,
                                       const generic_onoff_set_params_t * p_in,
                                       const model_transition_t * p_in_transition,
                                       generic_onoff_status_params_t * p_out)
{
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "msg: SET: %d\n", p_in->on_off);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "rssi: %d\n", p_meta->p_core_metadata->params.scanner.rssi);

Hello,

If your main goal is getting the distance (and not necessarily RSSI), I just wanted to mention that RSSI is not the best way to get the distance between devices. If you are using NCS 2.2 you could have a look at our new distance measurement model instead, which is using the distance toolkit described in the webinar I linked to above.

I am not sure about what you meant by your second question though. Are you trying to measure the distance to other nodes by triangulating distances between multiple nodes?

I would like to add a relay node to this to extend my range, how would I go about editing the light/light switch example to configure this?

[Elfving]

To add a relay node, or to add the relay feature to your node? To add the relay feature use CONFIG_BT_MESH_RELAY=y. I believe it is added by default to most of our samples though.
