Hi,
I'm working on a multilink central device with SDK16, nRF52832.
I'm trying to connect the central to 2 peripherals with certain address. So I added 2 address filters in scan_init:
//BLE_NUS_C_DEF(m_ble_nus_c); /**< BLE Nordic UART Service (NUS) client instance. */
BLE_NUS_C_ARRAY_DEF(m_ble_nus_c, NRF_SDH_BLE_CENTRAL_LINK_COUNT);
NRF_BLE_GATT_DEF(m_gatt); /**< GATT module instance. */
//BLE_DB_DISCOVERY_DEF(m_db_disc); /**< Database discovery module instance. */
BLE_DB_DISCOVERY_ARRAY_DEF(m_db_disc, NRF_SDH_BLE_CENTRAL_LINK_COUNT);
NRF_BLE_SCAN_DEF(m_scan); /**< Scanning Module instance. */
NRF_BLE_GQ_DEF(m_ble_gatt_queue, /**< BLE GATT Queue instance. */
NRF_SDH_BLE_CENTRAL_LINK_COUNT,
NRF_BLE_GQ_QUEUE_SIZE);
static uint16_t m_ble_nus_max_data_len = BLE_GATT_ATT_MTU_DEFAULT - OPCODE_LENGTH - HANDLE_LENGTH; /**< Maximum length of data (in bytes) that can be transmitted to the peer by the Nordic UART service module. */
//b859decbd6fa
static uint8_t m_peripheral_addr1[6] = {0xb8, 0x59, 0xde, 0xcb, 0xd6, 0xfa};
//6a637c7022e1
static uint8_t m_peripheral_addr2[6] = {0x6a, 0x63, 0x7c, 0x70, 0x22, 0xe1};
/**@brief Function for initializing the scanning and setting the filters.
*/
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.connect_if_match = true;
init_scan.conn_cfg_tag = APP_BLE_CONN_CFG_TAG;
err_code = nrf_ble_scan_init(&m_scan, &init_scan, scan_evt_handler);
APP_ERROR_CHECK(err_code);
err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_ADDR_FILTER, m_peripheral_addr1);
APP_ERROR_CHECK(err_code);
err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_ADDR_FILTER, m_peripheral_addr2);
APP_ERROR_CHECK(err_code);
err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_ADDR_FILTER, false);
APP_ERROR_CHECK(err_code);
// err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_UUID_FILTER, &m_nus_uuid);
// err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_UUID_FILTER, false);
// APP_ERROR_CHECK(err_code);
}
NRF_BLE_SCAN_ADDRESS_CNT is set to 2;
CENTRAL_LINK_CNT and TOTAL_LINK_CNT is set to 2;
The software works as expected on 10040 DK, it could connect 2 peripherals with target address only.
But when I was trying to migrate the program to a DIY HW, the address filter seems disabled.
Did I make it work coincidentally on DK? Did I miss any configuration?
Thanks!
