Good afternoon.
I´m using nrf51-dk with SDK 9.0.0, s110 softdevice and uart nordic app on mobile. I have a program in my nrf51-dk that it sends and receives data between nrf51-dk and mobile device.
I want to send a data when mobile device establishes connection with my nrf51-dk, the problem is that the first time that mobile device establishes the connection doesn´t receive "Pulse c para calibra" but when I disconnect and connect again the mobile device with my nrf51-dk, it receives the data correctly.
I have modified "on_ble_evt" function.
static void on_ble_evt(ble_evt_t * p_ble_evt){
uint32_t err_code;
uint8_t instrucciones[20] = "Pulse c para calibra";
switch (p_ble_evt->header.evt_id){
case BLE_GAP_EVT_CONNECTED:
conectado = true;
nrf_delay_ms(1500);
ble_nus_string_send(&m_nus, instrucciones, 20);
app_timer_start(timer_id, APP_TIMER_TICKS(500, APP_TIMER_PRESCALER), NULL); //10 segundos para configurar
err_code = bsp_indication_set(BSP_INDICATE_CONNECTED);
APP_ERROR_CHECK(err_code);
m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
break;
case BLE_GAP_EVT_DISCONNECTED:
conectado = false;
temporizador_menu = tiempo_espera_menu;
limpiar_datos_recibidos_bluetooth();
app_timer_stop(timer_id);
err_code = bsp_indication_set(BSP_INDICATE_IDLE);
APP_ERROR_CHECK(err_code);
m_conn_handle = BLE_CONN_HANDLE_INVALID;
break;
case BLE_GAP_EVT_SEC_PARAMS_REQUEST:
// Pairing not supported
err_code = sd_ble_gap_sec_params_reply(m_conn_handle, BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP, NULL, NULL);
APP_ERROR_CHECK(err_code);
break;
case BLE_GATTS_EVT_SYS_ATTR_MISSING:
// No system attributes have been stored.
err_code = sd_ble_gatts_sys_attr_set(m_conn_handle, NULL, 0, 0);
APP_ERROR_CHECK(err_code);
break;
default:
// No implementation needed.
break;
}
}
Screen of data received by mobile device:
Thank you.
