hi,
as we know, the device need to being linked in 1.28s if Advertising types is BLE_GAP_ADV_TYPE_ADV_DIRECT_IND ,but my host can't link device in 1.28s,so i want to link specific host by whitelist,but i can't achieve,i see log by MCP in the follow:
[11:23:14.5]Connected to address:DAFB328A3A10
[11:23:14.5]Starting a Read information Request on the whole remote DB
[11:23:14.6]lost connection to divice Reason:BTLE_CONN_FAILED_TO_BE_ESTABLISHED
[11:23:14.6]SERVER:Received packet<HicEvent:eventCode=0x0A>-<HicEvent:eventCode=0x0A>
[11:23:14.6]SERVER:Received Link Loss
my project is ble_app_uart,and related code be show in the follow
ble_gap_addr_t ble_gap_addr_01=
{BLE_GAP_ADDR_TYPE_RANDOM_STATIC,
{0x73,0x8c,0x9b,0xb7,0xd5,0xa9}};
ble_gap_addr_t *address[1]=
{
&ble_gap_addr_01,
};
static void advertising_start(void)
{
uint32_t err_code;
ble_gap_adv_params_t adv_params;
ble_gap_whitelist_t whitelist;
// Start advertising
memset(&adv_params, 0, sizeof(adv_params));
adv_params.type = BLE_GAP_ADV_TYPE_ADV_IND;
adv_params.p_peer_addr = NULL;
adv_params.fp = BLE_GAP_ADV_FP_FILTER_CONNREQ;
adv_params.interval = APP_ADV_INTERVAL;
adv_params.timeout = APP_ADV_TIMEOUT_IN_SECONDS;
whitelist.pp_addrs=address;
whitelist.addr_count=1;
adv_params.p_whitelist=&whitelist;
err_code = sd_ble_gap_adv_start(&adv_params);
if(err_code!=NRF_SUCCESS)
{
simple_uart_putstring((const uint8_t *)"advNO_NRF_SUCCESS\n");
printf_err_code(err_code);
}
else
{
simple_uart_putstring((const uint8_t *)"advNRF_SUCCESS\n");
}
APP_ERROR_CHECK(err_code);
nrf_gpio_pin_set(ADVERTISING_LED_PIN_NO);
}
