| 1# Welcome to BTstack 2 3BTstack is [BlueKitchen's](https://bluekitchen-gmbh.com) implementation of the official Bluetooth stack. 4It is well suited for small, resource-constraint devices 5such as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint. 6 7Targeting a variety of platforms is as simple as providing the necessary UART, CPU, and CLOCK implementations. BTstack is currently capable of connecting to Bluetooth-modules via: (H2) HCI USB, (H4) HCI UART + TI's eHCILL, and (H5) HCI Three-Wire UART. 8 --- 15 unchanged lines hidden (view full) --- 24 25 26### Supported Protocols and Profiles 27 28**Protocols:** L2CAP (incl. Enhanced Retransmission Mode and LE Data Channels), RFCOMM, SDP, BNEP, AVDTP, AVCTP, ATT, SM (incl. LE Secure Connections and Cross-transport key derivation). 29 30**Profiles:** A2DP, AVRCP incl. Browsing, GAP, GATT, HFP, HID, HSP, IOP, SPP, PAN, PBAP Client. 31 | 1# Welcome to BTstack 2 3BTstack is [BlueKitchen's](https://bluekitchen-gmbh.com) implementation of the official Bluetooth stack. 4It is well suited for small, resource-constraint devices 5such as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint. 6 7Targeting a variety of platforms is as simple as providing the necessary UART, CPU, and CLOCK implementations.
