Hi
I need to connect to perticular central and i know the central MAC address. So i am using whitelisting in peripheral.
I made below changes in my code in ble_app_uart but central getting connected disconnected so fast. Did i miss something to add in code or whats the problem?
1. When i used peer_addr.addr_type = BLE_GAP_ADDR_TYPE_PUBLIC; then peripheral is seen on nrf but not able to connect and when i set BLE_GAP_ADDR_TYPE_RANDOM_STATIC no peripheral is shown on nrf app.
static void on_adv_evt(ble_adv_evt_t ble_adv_evt)
{
uint32_t err_code;
ble_gap_addr_t peer_addr; //peer device address
ble_gap_addr_t const * p_peer_addr;
switch (ble_adv_evt)
{
case BLE_ADV_EVT_FAST:
err_code = bsp_indication_set(BSP_INDICATE_ADVERTISING);
APP_ERROR_CHECK(err_code);
break;
case BLE_ADV_EVT_IDLE:
sleep_mode_enter();
break;
case BLE_ADV_EVT_WHITELIST_REQUEST:
memset(&peer_addr, 0x01, sizeof(peer_addr));
////peer_addr.addr[0] = 0xbc; | Reverse the order you placed these:
////peer_addr.addr[1] = 0x41; |
////peer_addr.addr[2] = 0x01; | Also note that you used wrong address,
////peer_addr.addr[3] = 0x31; | as I said in my reply
////peer_addr.addr[4] = 0x8f; |
////peer_addr.addr[5] = 0x48; | Insert the address like this:
peer_addr.addr[5] = 0x41;
peer_addr.addr[4] = 0x4D;
peer_addr.addr[3] = 0x9E;
peer_addr.addr[2] = 0xF8;
peer_addr.addr[1] = 0x50;
peer_addr.addr[0] = 0xE1;
//// c1a7f5c23cc6
peer_addr.addr_type = BLE_GAP_ADDR_TYPE_PUBLIC; // Add the address type
////peer_addr pointers. Double pointers for the win! :S
p_peer_addr = &peer_addr;
////pp_peer_addr = &p_peer_addr; --> Remove this line
//// Set white list
err_code = sd_ble_gap_whitelist_set(&p_peer_addr, 0x01); //swap pp_peer_addr with &p_peer_addr, like this
if (err_code == NRF_SUCCESS)
{
printf("Successfully set whitelist!\r\n");
}
else
{
printf("Whitelist not set\r\n");
}
APP_ERROR_CHECK(err_code); //Added an error check, always useful to have.
//// White list reply
err_code = ble_advertising_whitelist_reply(&m_advertising,p_peer_addr, 1, NULL, (uint32_t) NULL);
if (err_code == NRF_SUCCESS)
{
printf( "Whitelist replied\r\n");
}
else
{
printf("Whitelist not replied\r\n");
}
APP_ERROR_CHECK(err_code);
break;
default:
break;
}
}
static void advertising_init(void)
{
ret_code_t err_code;
ble_advertising_init_t init;
memset(&init, 0, sizeof(init));
init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
init.advdata.include_appearance = false;
init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE; // Comment this line out if you havn't done it already
init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
init.advdata.uuids_complete.p_uuids = m_adv_uuids;
init.config.ble_adv_fast_enabled = true;
init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
init.config.ble_adv_fast_timeout = APP_ADV_DURATION;
init.advdata.flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED; // These two lines are correct
init.config.ble_adv_whitelist_enabled = true; //
init.evt_handler = on_adv_evt;
err_code = ble_advertising_init(&m_advertising, &init);
APP_ERROR_CHECK(err_code);
ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}
Please suggest how to connect one peripheral to particular central?
