Problem Statement:
I have two eval kits, one running peripheral role and the other central role. I'm trying to use the SCAN_ADDR_FILTER option so the central will connect to this specific peripheral by address.
What I've tried:
I've hard-coded the peripheral's address into the central code per various SDK examples.
If I change to a name-based filter, the peripheral is discovered and connected successfully. So it is verified to be advertising and connectable.
Code snippet from Central app:
static ble_gap_addr_t m_target_periph_addr =
{
.addr_type = BLE_GAP_ADDR_TYPE_RANDOM_STATIC,
.addr = {0xC1, 0x2E, 0x4A, 0xE0, 0x71, 0x81} // This matches what nRF Connect shows via Scan, for peripheral
};
...
static void scan_init(void)
{
ret_code_t err_code;
nrf_ble_scan_init_t init_scan;
memset(&init_scan, 0, sizeof(init_scan));
init_scan.p_scan_param = &m_scan_param;
init_scan.connect_if_match = true;
err_code = nrf_ble_scan_init(&m_scan, &init_scan, scan_evt_handler);
APP_ERROR_CHECK(err_code);
if (is_connect_per_addr)
{
err_code = nrf_ble_scan_filter_set(&m_scan,
SCAN_ADDR_FILTER,
m_target_periph_addr.addr);
APP_ERROR_CHECK(err_code);
}
err_code = nrf_ble_scan_filters_enable(&m_scan,
NRF_BLE_SCAN_ALL_FILTER,
false);
APP_ERROR_CHECK(err_code);
}
Questions:
Am I using the wrong type of address (RANDOM_STATIC)?
Is there I setting I need to update in the peripheral app to make address filtering work?
