Check browser capabilities in standby mode

[capital-G]

Currently it is unclear if for iOS/Android

• the browser still receives webRTC on standby
• sends GPS on standby
• under which cases the OS just closes down the browser
• are tab switches allowed?

Please extend :)

I will be testing gps throughput in a custom environment with a quick node server and socketIO connection.
What about the webrtc testing? Should i just play the demo and play around to see if stream turns off in some cases?

Interesting stuff will be continuing the stream from the control center after listening to some music or getting a call.

@vin-ni will do a check with standby and gps transmissions and update of stream variables

Lets create a script which logs all GPS variables

Some research today

Screen on

Number of events that are received on the server - latitude and longitude is transferred individually

No dropouts

Every 1 to 2 seconds we receive an update.

It takes around 30s to get really accurate results (yscale is log!)

Heading seems sometimes reliable - have in mind that the skips occur on the 360 to 0 crossover, unwrapping them reveals this

Unwrapping the values reveals that they are indeed useful.

Plotting the long/lat on a map results in this nice plot

Which is much more accurate than I would have thought.

Amazing!
Yes, we're using the "accurate" flag for gps I believe.

Sadly GPS does not work/update if the screen is locked :/

So microphone and GPS is not working if the screen is locked.
This could probably be circumvented through a native app.

The first half is completely missing, I turned the screen on for the 2nd half

ToDo @vin-ni

• Check if Social Score still updates GPS if screen is locked (it does not for Gencaster)
• Do PWA allow playback of audio in the background?
• Consider Not working with Safari IOS 15.0 richtr/NoSleep.js#135 (comment)
