扩充 CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP 的值空间 (AEGHB-1315)

[wppurking]

Description

In the esp_ble_conn_ext_advertise method, the adv_params are assigned using CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(0) ~ BIT(7), but now only 0~15 can be set, at most controlling BIT(0) ~ BIT(3), unable to control the higher bits BIT(4) ~ BIT(7). If expanded to BIT(7), it should be 0xFF, which in decimal is 255.

I have tried doing the following:

    /* extended advertising capability */
    adv_params.connectable = !!(CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(0));
    adv_params.scannable = !!(CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(1));
    adv_params.directed = !!(CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(2));
    adv_params.high_duty_directed = !!(CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(3));
    adv_params.legacy_pdu = !!(CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(4));
    adv_params.anonymous = !!(CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(5));
    adv_params.include_tx_power = !!(CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(6));
    adv_params.scan_req_notif = !!(CONFIG_BLE_CONN_MGR_EXTENDED_ADV_CAP & BIT(7));

But I must have done something wrong with my cap value: 83 (01010011) because I have:

E (15563) blecm_nimble: Configure extended advertising instance error; rc=3
