Subscribe command will enable notify or indicate events from the characteristic, depending on supported characteristic properties, and print received values to the output window. Unsubscribe will stop notify or indicate events. Rename find_attribute() to find_characteristic() and return a characteristic for a set of UUIDS, a characteristic for an attribute handle, or None. Print read and received values has a hex string. Add an unsubscribe implementation to gatt_client.py. Reset the CCCD bits to 0x0000. Remove a matching subsciber, if one is provided. Otherwise remove all subscribers for a characteristic, since no more notify or indicates events will be comming. authored-by: Michael Mogenson <mogenson@google.com>

Apps
show.py
Parse a file with HCI packets and print the details of each packet in a human readable form
link_relay.py
Simple WebSocket relay for virtual RemoteLink instances to communicate with each other through.
hci_bridge.py
This app acts as a simple bridge between two HCI transports, with a host on one side and a controller on the other. All the HCI packets bridged between the two are printed on the console for logging. This bridge also has the ability to short-circuit some HCI packets (respond to them with a fixed response instead of bridging them to the other side), which may be useful when used with a host that send custom HCI commands that the controller may not understand.
Usage
python hci_bridge.py <host-transport-spec> <controller-transport-spec> [command-short-circuit-list]
Examples
UDP to HCI UART
python hci_bridge.py udp:0.0.0.0:9000,127.0.0.1:9001 serial:/dev/tty.usbmodem0006839912171,1000000 0x3f:0x0070,0x3f:0x0074,0x3f:0x0077,0x3f:0x0078
PTY to Link Relay
python hci_bridge.py serial:emulated_uart_pty,1000000 link-relay:ws://127.0.0.1:10723/test
In this example, an emulator that exposes a PTY as an interface to its HCI UART is running as a Bluetooth host, and we are connecting it to a virtual controller attached to a link relay (through which the communication with other virtual controllers will be mediated).
NOTE: this assumes you're running a Link Relay on port 10723.
console.py
A simple text-based-ui interactive Bluetooth device with GATT client capabilities.
