ESP-Bluedroid is a modified version of the native Android Bluetooth stack, Bluedroid. It consists of two layers: the Bluetooth Upper Layer (BTU) and the Bluetooth Transport Controller layer (BTC). The BTU layer is responsible for processing bottom layer Bluetooth protocols such as L2CAP, GATT/ATT, SMP, GAP, and other profiles. The BTU layer provides an interface prefixed with "bta". The BTC layer is mainly responsible for providing a supported interface, prefixed with "esp", to the application layer, processing GATT-based profiles and handling miscellaneous tasks. All the APIs are located in the ESP_API layer. Developers should use the Bluetooth APIs prefixed with "esp".
