Read data in real time
Is it possible to view the data real time on another screen rather than post lap?
Also is there, or will there be support for data to be recorded and or viewed on a Chromebook or Android device.
Cheers

Oh using in F1 2019.

unfortunately "real-time output" is not a feature at the moment, but it is something we would like to support in the future.

Data received from the network protocols are usually quite "noisy": packets arrive in unspecified order and some packets can go lost. So we have to reorder them and fill the missing ones later, this adds a first layer of "delay" in data processing.
In addition, data received are usually not directly suitable for telemetry output: telemetry data must be mapped against distances on track, but the data we receive have a lot of "holes" (e.g. due the real-time sampling, a vehicle moving at 300 kph sampled at 20Hz moves 4 meters between 2 samples). We have a relatively complex algorithm that "fills the missing holes", reconstructing a proper telemetry stream for every distance on track, creating a discrete representation of the track and using different algorithms for every type of telemetry parameter (eg: "gears" can't be interpolated, while "fuel" could; radial parameters must be interpolated with special formulas, the same for vectors where their modulus has a particular meaning; etc). In addition there are games that allow the user to "travel backward in time" (e.g. the F1 series), that add a lot of further complexity to this algorithm. Unfortunately, at the moment, this algorithm can't operate in real-time while receiving data.

SRT is available also on iOS ( https://itunes.apple.com/us/app/sim-racing-telemetry/id1288695792?ls=1&mt=8 ) and Android ( https://play.google.com/store/apps/details?id=com.unamedia.srt ).

A developer of this app has indicated that this post answers the original topic.
