# blue_cr

Bluetooth interface using crystal and bluez

## Installation

Add this to your application's `shard.yml`:

```yaml
dependencies:
  blue_cr:
    github: NeuraLegion/blue_cr
```

## Usage

```crystal
require "blue_cr"

# List all adaptors in the machine (hci*)
adaptors = BlueCr.list_adaptors

# Get first avilable adaptor and get back the adaptor object
adaptor = BlueCr::Adaptor.new(adaptors.first)

# Start discovery
adaptor.start_discovery
sleep 5

# Get back array of all device address
devices = adaptor.list_devices
adaptor.stop_discovery

# For each device found, get some info
devices.each do |name|
      device = adaptor.get_device(name)
      if device
        begin
          next unless device.alive?
          puts device.connect
          sleep 5
          device.refresh
          puts "#######################"
          puts "Device: #{device.name}"
          puts "Address: #{device.address}"
          puts "UUIDs: #{device.uuids}"
          puts "Dump: #{device.all_properties}"
          device.list_services
          device.services.each do |uuid, service|
            puts "Service: #{uuid}: #{service.service_type}"
            service.list_characteristics
            service.characteristics.each do |uuid, char|
              puts "  Characteristic: #{uuid}: #{char.characteristic_type}"
              puts "  Value: #{char.read_value}"
            end
          end
          puts "#######################\n"
          puts device.disconnect
        rescue Exception
          next
        end
      end
    end
  end
end
```


## Development

- [x] scan for devices and get back array of addresses  
- [x] connect to a remote device  
- [x] send arbitery commands to remote device  
- Additional features should be asked for via Issues.
