discovery does not appear return any devices

[gjr80]

Using --discover results in the following error:

It appears that discovery is not returning any device addresses.

Local testing of GatewayApi.discover() appears to indicate on-line gateway devices are responding, the response is received and the response is valid.

Need to check decoding/parsing of the responses.

Strange - discovery (and the driver) works great here. Debian 11/bullseye, Py3, WeeWX 4.10.2 installed via apt, and gw1000 driver v0.5.0b6:

$ PYTHONPATH=/usr/share/weewx python -m user.gw1000 --discover

Same problem here. Weewx 4.10.2 installed via apt on Operating System: Raspbian GNU/Linux 10 (buster), Kernel: Linux 5.10.103-v7+, Architecture: arm, gw1000 driver v. 0.6.0b2.
