RE: How to switch between beacon modes without buttons?

Hi Adam I also interesting about this application, so I modified the Beacon Source code to obtain the same result without press SW2 button. For the other point, entry in DFU without press SW1, I'm still working but I didn't found any solution. Below you can find a snippet code for the first step:

in the main.c you must put:

if (mode == beacon_mode_config) { uint32_t err_code; ble_advdata_t advdata; ble_advdata_t scanrsp; ble_advdata_manuf_data_t manuf_specific_data; uint8_t flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

		  manuf_specific_data.company_identifier = APP_COMPANY_IDENTIFIER;
    manuf_specific_data.data.p_data        = (uint8_t *) clbeacon_info;
    manuf_specific_data.data.size          = APP_BEACON_INFO_LENGTH;
		
    ble_uuid_t adv_uuids[] = {{BCS_UUID_SERVICE, m_bcs.uuid_type}};

    // Build and set advertising data
    memset(&advdata, 0, sizeof(advdata));
    //advdata.name_type               = BLE_ADVDATA_FULL_NAME;
    advdata.include_appearance      = false;
    advdata.flags.size              = sizeof(flags);
    advdata.flags.p_data            = &flags;
			advdata.p_manuf_specific_data   = &manuf_specific_data;
    
    memset(&scanrsp, 0, sizeof(scanrsp));
			scanrsp.name_type                = BLE_ADVDATA_FULL_NAME;
    scanrsp.uuids_complete.uuid_cnt  = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
    scanrsp.uuids_complete.p_uuids   = adv_uuids;
    
    err_code = ble_advdata_set(&advdata, &scanrsp);
    APP_ERROR_CHECK(err_code);
    
    // Initialize advertising parameters (used when starting advertising).
    memset(&m_adv_params, 0, sizeof(m_adv_params));
    
    m_adv_params.type        = BLE_GAP_ADV_TYPE_ADV_IND;
    m_adv_params.p_peer_addr = NULL;
    m_adv_params.fp          = BLE_GAP_ADV_FP_ANY;
    m_adv_params.interval    = APP_ADV_INTERVAL;
    m_adv_params.timeout     = APP_ADV_TIMEOUT_IN_SECONDS;           
}
else
{
    APP_ERROR_CHECK_BOOL(false);
}

comment the lines:

//err_code = app_button_is_pushed(CONFIG_MODE_BUTTON_PIN, &config_mode); //APP_ERROR_CHECK(err_code);

finally you must remember to put: bool config_mode = true;

In this mode the beacon is always connectable.

If anyone have suggestion to entry in bootloader mode without press SW1, please reply in this thread, thank you. I read the question in devzone.nordicsemi.com/.../ but I can not understand the operation of the function:

static void on_write(ble_evt_t * p_ble_evt) { ble_gatts_evt_write_t * p_evt_write = &p_ble_evt->evt.gatts_evt.params.write; if (p_evt_write->handle == 3) // device name handle { NRF_POWER->GPREGRET = 1; sd_nvic_SystemReset(); } }

What is the device name handle? And in which source code I must to put this function?

I'm waiting for an answer, thank you.
