Bluedroid Rust wrapper

This is a Rust wrapper for the Bluedroid Bluetooth stack for ESP32. It allows you to build a GATT server with a declarative API and supports multithreading.

Usage

Declare a characteristic:

let manufacturer_name_characteristic = Characteristic::new(BleUuid::Uuid16(0x2A29))
      .name("Manufacturer Name String")
      .permissions(AttributePermissions::new().read().write())
      .properties(CharacteristicProperties::new().read().write().notify())
      .max_value_length(20)
      .on_write(|data, param| {
          info!("Received write request: {:?} {:?}", data, param);
      })
      .show_name()
      .set_value("Hello, world!".as_bytes().to_vec())
      .build();

Declare a service:

let device_information_service = Service::new(BleUuid::Uuid16(0x180A))
    .name("Device Information")
    .primary()
    .characteristic(&manufacturer_name_characteristic)
    .build();

Declare a profile and start the server:

let profile = Profile::new(0x0001)
    .name("Device Information")
    .service(&device_information_service)
    .build();

GLOBAL_GATT_SERVER
    .lock()
    .unwrap()
    .profile(profile)
    .device_name("ESP32-GATT-Server")
    .appearance(Appearance::WristWornPulseOximeter)
    .advertise_service(&device_information_service)
    .start();
