Remove telemetry processing from frontend #105

aywaldron · 2019-03-20T22:45:32Z

Current Behavior

Currently, the backend of the GUI sends an entire packet to the frontend, where the packet must be decommed and processed for display in the GUI. This optimizes bandwidth, but duplicates packet decomming/processing code in both the frontend and backend, which makes maintenance difficult.

Desired Behavior

All packet decomming/processing will happen on the backend of the GUI, and only changed packet fields will be sent to the front end for updated display. This will improve code maintenance and still prioritize bandwidth.

Proposed Changes

Remove all telemetry decomm/processing from front end of GUI
Track state on back end and propagate to the front end
Only updated packet fields will be sent to frontend (dict of name: value pairs that were changed from last packet)
To keep ability to view both raw and dntoeu values on frontend, have to send both
Remove limit monitoring from front end
Redraw tries to redraw all fields from latest packet - we will have to keep track of what the previous value was for fields that are not changed since front end will need to redraw them
Plotting functions will need rewrite
Event emission in frontend should only happen every x seconds (current configuration in GUI) - will need to keep track of deltas its gotten since last emit and aggregate all of them for next emit

- Update tlm/realtime route to send packet to front end in JSON format - Update TelemetryStream on frontend to parse JSON formatted packet - Update plotting on frontend to work with JSON formatted packet - Update getting field values from packet on frontend to work with JSON

… end

When a message is received the GUI now checks to see if the topic is within its log and telem stream name attributes, and if so, processes the message accordingly. If these attributes do not exist or if the received topic is in not in them, the GUI checks if the topic contains either "telem_stream" or "log_stream" and processes accordingly. If none of these conditions are met, an error is thrown that a message with an unrecognized topic has been received.
