aio-rfcomm
Talk to Bluetooth Classic serial devices from asyncio — the same way on Linux, macOS and Windows.
async with (
aio_rfcomm.open_bluetooth() as bluetooth,
bluetooth.open_service(DEVICE, MY_SERVICE) as channel,
):
await channel.send(b"hello\n")
while True: # until the connection ends, raising ChannelClosedError
print((await channel.receive()).decode(), end="")
That is the whole idea. RFCOMM is how many Bluetooth gadgets that predate BLE still talk — printers, GPS units, robots, serial adapters, a great many embedded boards — and reaching one from Python has meant a different library, a different API and a different set of surprises on every platform.
This is one API for all three, running in your own event loop, with every
connection owned by an async with block that cleans up after itself.
Install
$ uv add aio-rfcomm
It needs Python 3.11 or newer. The documentation is at https://dlech.github.io/aio-rfcomm/.
Serving, too
Publish a service and let devices connect to you:
async with bluetooth.serve(MY_SERVICE, name="my thing") as service:
async for request in service.connection_requests():
... # accept it, in a task of your own
