- feat(soc_caps): Enable BT Classic and BLE in esp32s31 - Add git submodule for ESP32-S31 bt controller lib files - changed sdkconfig.defaults and README for Bluetooth Classic examples - change(docs): Added vendor HCI documentations for ESP32-S31 - change(Bluedroid): Adapt to ESP32-S31 due to some API differences on Bluetooth controller from ESP32 - change(bt): Modify CMakeLists.txt to support the Bluetooth dual-mode architecture on ESP32-S31 - change(bt): Add ECC P-192 functions to tinycrypt
