esp_bt_mem_release() function

Release the Controller memory, BSS and data section of the Classic Bluetooth/BLE Host stack as per the mode This function first releases Controller memory by internally calling `esp_bt_controller_mem_release()`, then releases Host memory. If you never intend to use Bluetooth in a current boot-up cycle, calling `esp_bt_mem_release(ESP_BT_MODE_BTDM)` could release the BSS and data consumed by both Classic Bluetooth and BLE stack to heap. If you intend to use BLE only, calling `esp_bt_mem_release(ESP_BT_MODE_CLASSIC_BT)` could release the BSS and data consumed by Classic Bluetooth. You can then continue using BLE. If you intend to use Classic Bluetooth only, calling `esp_bt_mem_release(ESP_BT_MODE_BLE)` could release the BSS and data consumed by BLE. You can then continue using Classic Bluetooth. For example, if you only use Bluetooth for setting the Wi-Fi configuration, and do not use Bluetooth in the rest of the product operation, after receiving the Wi-Fi configuration, you can disable/de-init Bluetooth and release its memory. Below is the sequence of APIs to be called for such scenarios: esp_bluedroid_disable(); esp_bluedroid_deinit(); esp_bt_controller_disable(); esp_bt_controller_deinit(); esp_bt_mem_release(ESP_BT_MODE_BTDM);
