OT-BLUETOOTH, embedded Bluetooth protocol stack is a highly-configurable, resource-efficient protocol stack targeted at embedded Bluetooth devices and applications. It is written entirely in ANSI C with simple and well-defined interface.

Easy to learn, easy to use, easy to port

OT-BLUETOOTH is available as cleanly documented source code with well defined APIs and examples. The OT-BLUETOOTH provides full configuration to all elements of the protocol stack, allowing developers to make efficient use of memory and processor power for devices with tight resource constraints. Very little knowledge of the Bluetooth protocol is necessary to develop an embedded Bluetooth application with OT-BLUETOOTH software. OT-BLUETOOTH can be easily ported to new RTOS and CPU environments by implementing a thin layer that provides OS and Hardware abstraction.

Features

OT-BLUETOOTH currently supports the following features. We continuously add new profiles and enhance the interface to make it more user friendly software.

Memory Usage

As you can see from the following table, OT-BLUETOOTH uses very little memory that makes it a perfect choice for embedded devices with tight resource constraints.

Module	Image Size (bytes)	RAM usage (bytes)
L2CAP	16520	1480
HCI	22048	812
HCI UART	5456	380
HCI USB (USB Host Stack)	28576	17944

Architecture

OT-BLUETOOTH architecture and design strictly confirms to the Bluetooth Core Specifications. The following diagram shows the supported layers within the Bluetooth stack. All layers are configurable by the user.

Integration and Support

We provide our customers more than just a software drop. We provide training, support, application customization, porting, and other services. We are flexible and committed to provide anything to our customers to develop better embedded Bluetooth products that reach the market faster and at lower development cost.
