Bluetooth Latency

[gabsanabria88]

Hi, I'm looking to build my first wireless wheel based on this very detailed project.

I just have one question that I couldn't find much information about:

What kind of input latency should I expect when using Bluetooth?
Will it noticeably affect my driving, or is it negligible?

Thank you in advance!

Thanks for your support.

What kind of input latency should I expect when using Bluetooth? Will it noticeably affect my driving, or is it negligible?

This is a good question. The answer depends on what you consider “an input”.
The simple push of a button requires more time from your muscles than from the electronics.
Therefore, you can rest assured. On the other hand, if you are referring to the reception and display of telemetry data (or pixels),
you may experience a slight delay depending on the hardware (e.g. the number of pixels).
The firmware is designed so that this delay does not affect the button inputs at all, which is the important thing.

The latency you can expect from this firmware is the same as you would expect from a wireless gamepad, i.e. unnoticeable.

Hi!

Thank you very much for the explanation! That’s exactly the kind of answer I was hoping for. It gives me a lot more confidence to proceed with my wireless wheel project.

Congratulations on your amazing work on this firmware! Really appreciate your time and dedication.
