# Bluetoe [](https://travis-ci.org/TorstenRobitzki/bluetoe) [](https://gitter.im/TorstenRobitzki/bluetoe?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [](https://lgtm.com/projects/g/TorstenRobitzki/bluetoe/context:cpp)  ## Putin's Invasion of Ukraine Please consider donating to one of the funds that help victims of the war in Ukraine: - https://spendenkonto-nothilfe.de ## Overview Bluetoe implements a GATT server with a very low memory footprint and a convenient C++ interface. Bluetoe makes things easy but gives you the opportunity to fiddle with all the low-level GATT details if necessary. Bluetoe's primary target is very small microcontrollers. Here is a complete example of a small GATT server that allows a client to controll an IO pin, running on a nRF52832: #include #include #include using namespace bluetoe; // LED1 on a nRF52 eval board static constexpr int io_pin = 17; static std::uint8_t io_pin_write_handler( bool state ) { // On an nRF52 eval board, the pin is connected to the LED's cathode. This inverts the logic. NRF_GPIO->OUT = state ? NRF_GPIO->OUT & ~( 1 << io_pin ) : NRF_GPIO->OUT | ( 1 << io_pin ); return error_codes::success; } using blinky_server = server< service< service_uuid< 0xC11169E1, 0x6252, 0x4450, 0x931C, 0x1B43A318783B >, characteristic< requires_encryption, free_write_handler< bool, io_pin_write_handler > > > >; blinky_server gatt; device< blinky_server > gatt_srv; int main() { // Init GPIO pin NRF_GPIO->PIN_CNF[ io_pin ] = ( GPIO_PIN_CNF_DRIVE_S0H1 << GPIO_PIN_CNF_DRIVE_Pos ) | ( GPIO_PIN_CNF_DIR_Output << GPIO_PIN_CNF_DIR_Pos ); for ( ;; ) gatt_srv.run( gatt ); } ## Documentation http://torstenrobitzki.github.io/bluetoe/ ## L2CAP Bluetoe ships with its own fully-usable link layer based on the nRF52832. The link layer implementation is based and tested on an abstract device called a scheduled radio, and should be easy to port to similar hardware. As Bluetoe is a GATT server implementation, only parts of the link layer relevant to GATT have been implemented. Bluetoe can be easily adapted to any other existing L2CAP implementation (those based on HCI, for example). ## Current State The following table shows the list of supported GATT procedures, along with and their current and planned implementation status: Feature | Sub-Procedure | Status --------|---------------|------- Server Configuration|Exchange MTU|implemented Primary Service Discovery|Discover All Primary Services|implemented
