When adding multiple devices that are offline the serial port is blocking waiting for timeout

[kenhun93]

Hi Ryan,

I've been inspired by your project, and im trying to create a OSDP control panel with some OSDP readers i have laying around.
However when i try to add multiple devices the serial port is blocked while waiting for the device to respond (this is when device is offline).
cp.add_device(connection_id=bus_id, address=2, use_crc=False, use_secure_channel=False) cp.add_device(connection_id=bus_id, address=1, use_crc=False, use_secure_channel=False)

The traceback looks like this:
Traceback (most recent call last): File "C:\Users\Kenneth\PycharmProjects\OSDP\venv\lib\site-packages\osdp\_bus.py", line 95, in run_polling_loop reply = self.send_command_and_receive_reply(data, command, device) File "C:\Users\Kenneth\PycharmProjects\OSDP\venv\lib\site-packages\osdp\_bus.py", line 158, in send_command_and_receive_reply raise TimeoutError("Timeout waiting for reply message") TimeoutError: Timeout waiting for reply message

Could you please advice in case im doing something silly?
Thank you in advance!
