Bluetooth Classic

[中文]

Bluedroid

• Previously, the use of SDP APIs was affected by the CONFIG_BT_L2CAP_ENABLED configuration, although there was no relationship between them. The new Kconfig option CONFIG_BT_SDP_COMMON_ENABLED has been introduced to separate common SDP operations from Classic Bluetooth L2CAP functionality. It shall be enabled before calling SDP related APIs.

• The following Bluedroid API have been changed:

  • /bt/host/bluedroid/api/include/api/esp_sdp_api.h

    • Field user2_ptr_len and user2_ptr is deprecated in structure esp_bluetooth_sdp_hdr_overlay_t, since they are not used in SDP record creation or searching.

Bluetooth Common APIs

• /bt/include/esp32/include/esp_bt.h
