关于ESP32S3使用nimble库主动扫描，扫描不到响应数据包的问题
Posted: Sat May 20, 2023 7:50 am
使用的例程路径：esp-idf-v4.4.4/esp-idf-v4.4.4/examples/bluetooth/nimble/blecent
将static void blecent_scan(void)做如下修改：
static void blecent_scan(void)
{
uint8_t own_addr_type;
struct ble_gap_disc_params disc_params;
int rc;
/* Figure out address to use while advertising (no privacy for now) */
rc = ble_hs_id_infer_auto(0, &own_addr_type);
if (rc != 0)
{
MODLOG_DFLT(ERROR, "error determining address type; rc=%d\n", rc);
return;
}
/* Tell the controller to filter duplicates; we don't want to process
* repeated advertisements from the same device.
*/
disc_params.filter_duplicates = 0;
/**
* Perform a passive scan. I.e., don't send follow-up scan requests to
* each advertiser.
*/
disc_params.passive = 0;
/* Use defaults for the rest of the parameters. */
disc_params.itvl = 0;
disc_params.window = 0;
disc_params.filter_policy = 0;
disc_params.limited = 0;
rc = ble_gap_disc(own_addr_type, BLE_HS_FOREVER, &disc_params, blecent_gap_event, NULL);
if (rc != 0)
{
MODLOG_DFLT(ERROR, "Error initiating GAP discovery procedure; rc=%d\n",
rc);
}
}
在static int blecent_should_connect(const struct ble_gap_disc_desc *disc)中进行广播包以及扫描响应数据包的打印输出：
static int blecent_should_connect(const struct ble_gap_disc_desc *disc)
{
struct ble_hs_adv_fields fields;
int rc;
int i;
/* The device has to be advertising connectability. */
if (disc->event_type != BLE_HCI_ADV_RPT_EVTYPE_ADV_IND &&
disc->event_type != BLE_HCI_ADV_RPT_EVTYPE_DIR_IND)
{
return 0;
}
rc = ble_hs_adv_parse_fields(&fields, disc->data, disc->length_data);
if (rc != 0)
{
return rc;
}
ESP_LOGI(tag, "length_data = %d", disc->length_data);
for (int i = 0; i < disc->length_data; i++)
{
printf("%02X ", disc->data);
}
printf("\n");
if (strlen(CONFIG_EXAMPLE_PEER_ADDR) && (strncmp(CONFIG_EXAMPLE_PEER_ADDR, "ADDR_ANY", strlen("ADDR_ANY")) != 0))
{
ESP_LOGI(tag, "Peer address from menuconfig: %s", CONFIG_EXAMPLE_PEER_ADDR);
/* Convert string to address */
sscanf(CONFIG_EXAMPLE_PEER_ADDR, "%hhx:%hhx:%hhx:%hhx:%hhx:%hhx",
&peer_addr[5], &peer_addr[4], &peer_addr[3],
&peer_addr[2], &peer_addr[1], &peer_addr[0]);
if (memcmp(peer_addr, disc->addr.val, sizeof(disc->addr.val)) != 0)
{
return 0;
}
}
/* The device has to advertise support for the Alert Notification
* service (0x1811).
*/
for (i = 0; i < fields.num_uuids16; i++)
{
if (ble_uuid_u16(&fields.uuids16.u) == BLECENT_SVC_ALERT_UUID)
{
return 1;
}
}
return 0;
}
期望的结果：能够扫描到广播包与扫描响应数据包；
