I'm glad to hear that!

Be sure to let us know if you have any other issues.

Best regards,

Hi, thanks fort the reply.

I didn't notice there were various kinds of logs (Debug / Info), changing the log level to 4 solved it, from there it was easy to notice that RSSI variable type was not signed int as should be, hence not showing neg. values.

It works perfectly now, thank you!

Marco.

Hi!

I'm not quite sure why you aren't seeing the output from NRF_LOG_DEBUG().
I can't see any other debug outputs in the screenshots you uploaded either.
Are you sure that you have the NRF_LOG_DEFAULT_LEVEL set to debug (level 4) in your sdk_config.h file?

Also double check that you are receiving the BLE_GAP_EVT_RSSI_CHANGED event?

As for what you want to acheive here;
I tried to implement it myself, in the ble_app_multiperipheral/ble_app_blinky_c.
I didn't do it the exact same way you did, but I had no issue printing the RSSI values on the debug terminal in SES.

My code;

/**@brief Function for handling BLE events.
 *
 * @param[in]   p_ble_evt   Bluetooth stack event.
 * @param[in]   p_context   Unused.
 */
static void ble_evt_handler(ble_evt_t const * p_ble_evt, void * p_context)
{
    ret_code_t err_code;
    int8_t rssi;
    uint8_t channel;

    switch (p_ble_evt->header.evt_id)
    {
        case BLE_GAP_EVT_CONNECTED:
            on_connected(&p_ble_evt->evt.gap_evt);
            break;

        case BLE_GAP_EVT_DISCONNECTED:
            on_disconnected(&p_ble_evt->evt.gap_evt);
            break;

        case BLE_GAP_EVT_RSSI_CHANGED:

            err_code = sd_ble_gap_rssi_get (p_ble_evt->evt.gap_evt.conn_handle, &rssi, &channel);
            
            NRF_LOG_DEBUG("RSSI is; %d", rssi); 
            break;

/**@brief Function for handling the Connected event.
 *
 * @param[in] p_gap_evt GAP event received from the BLE stack.
 */
static void on_connected(const ble_gap_evt_t * const p_gap_evt)
{
    ret_code_t  err_code;
    uint32_t    periph_link_cnt = ble_conn_state_peripheral_conn_count(); // Number of peripheral links.

    NRF_LOG_INFO("Connection with link 0x%x established.", p_gap_evt->conn_handle);

    // Assign connection handle to available instance of QWR module.
    for (uint32_t i = 0; i < NRF_SDH_BLE_PERIPHERAL_LINK_COUNT; i++)
    {
        if (m_qwr[i].conn_handle == BLE_CONN_HANDLE_INVALID)
        {
            err_code = nrf_ble_qwr_conn_handle_assign(&m_qwr[i], p_gap_evt->conn_handle);
            APP_ERROR_CHECK(err_code);
            break;
        }
    }

    err_code = app_button_enable();
    APP_ERROR_CHECK(err_code);

    sd_ble_gap_rssi_start(p_gap_evt->conn_handle, 5, 0);

Cheers,
Joakim.
