Scorpius design and functionality always refers to 1:1 racing to keep it as real as possible.
Radio comms in motorsport has been around since the late 40s. Its critical and handy to have important information.
SmartRace has Smart Connect which can do this but only for 6 cars and only for Carrera.

Screens are great but you cant look at a screen and race and concentrate on a race simultaneously.
Announcements are great but it is impossible to hear everyone's at once.

So how to do?

Apps cant do custom RF but can do Bluetooth and Wi Fi and phones don't accept dongles.
Your PC can do RF via dongle, Bluetooth and Wi Fi.
Our race program, Scorpius Race Management, already has all the required data.

My proposal is to send all information globally using Wi Fi. Each app can be customised to a certain car ID 1-24.

Wifi and RF both operate generally on 2.4Ghz and will ad traffic.
The limits won’t be known until testing. For example it may be that there is a limitation on this, 6 cars for example, maybe more or less. No one knows yet.



Each drivers app decodes the global message and using text to voice will hear only their information, no one else.  Voice includes countdown to race start, false start, lap times, laps to go, new race leader, best lap times. time to go, fuel and tyre status can be heard.

As a project manager I need to plan well in advance. This is a ten year product meaning once its released there will be no hardware changes for a decade like Scorpius Generation 1 did successfully. It's a winning formula for the end user.
So everything must be planned years ahead. This is one such function, even though we may not get to this in 2025. It will happen.
But discussion, a specification is paramount with all the relevant engineers to foresee issues is required now not later, and plan accordingly for long term success with minimal back tracking of work as the MPD will be released as a car decoder first and then the other 9 MPD products added AFTER the MPD is released.

Here the system will eventually employ RF, BT and WiFi to get the job done.

Can we use a BT headset?
If the phone can keep up. Its limitations are not yet known.
In any case high speed Comms is not required for a simple audio message. 
Another bonus with wired is it keeps the traffic on the 2.4Hz hand less congested. 
The interesting about development is going places in the slot car world no one has been to before. 
Digital slot cars…. the new frontier with 10 million sq miles still to explore.

A third option is to use the proposed RF to BT converter. Here the converter sends directly to phone. App receives car telemetry. same as RF but in BT message.

This is perfect for a quick race up to 4 people.

The WiFi method gets you all the PC RMS functions though but your options will be scaled down from a full blown PC version.  

So the headset. Once you have race data either from PC or from car via RF/BT converter you can now send it to your headset. Basic information like race position, last lap, best lap, laps to go, time to go, laps until driver change come to mind. 

Smart Race app could be utilised if Scorpius car telemetry swapped ton Carrera BT protocols. Nitrous and SmartRace will be a nice combination.

Random information: Did you know the Scorpius MPD is capable of 100 million operations per second?
 
And features a real time operating system with parallel processing?

And an iPhone is capable of 16 trillion operations per second?

And the best F1 teams have 15 telemetry engineers on 15 PCs working simultaneously in the pits adjusting brakes, fuel mixtures, boost, aero etc in real time using information from over 200 in car sensors?
