Proxy Requires UART Telemetry to Create Queues

[kb1lqc]

In most cases this is only an issue if you configure Faraday to update over UART with a long interval ( >5 seconds could get annoying). The symptoms are:

• Proxy will respond with an error saying that callsign-nodeid does not exist or the port doesn't exist
• If UART is set to never update then you will never be able to get data from Faraday, even if it sends down Remote RF unit traffic.

Regardless, this is poor design. Proxy should know what's connected and what to expect prior to any data being sent down over USB.

It seems like this is still an issue https://github.com/FaradayRF/Faraday-Software/blob/master/Proxy/proxy.py#L69

Looking into items related to this. I've programmed a Faraday Radio to send UART packets every 15 seconds and am attempting to view the root page of the proxy flask server. This results in an error:

Fixed this in c50fe71 by separating the .upper() conversion from detection of a None type for callsign. Also added default None types to the other parameters.

            data = request.get_json(force=False)  # Requires HTTP JSON header
            port = request.args.get("port")
            callsign = request.args.get("callsign")
            nodeid = request.args.get("nodeid")

            # Convert callsign to uppercase
            if callsign:
                callsign = callsign.upper()

Fixed with PR #283
