    Hi all,

    I'm looking to go wireless with my SMC3 setup. Has anyone used a bluetooth HC-06 module instead of a USB cable to connect an Uno to a PC?

    Does the Bluetooth connection introduce noticeable latency, or is it stable enough for this platform?

    Thanks a lot.

    My experience with bluetooth has been for audio, which is far less critical, and the latency is way too high for anything that is time dependent.

    That said, SMC3 is used to configure the hardware used, not run constantly, so I can't really imagine a use case for trying to go with bluetooth, as once you get SM3 dialed in for your hardware you never have to mess with it, but perhaps you have something else in mind.

    Thanks noorbeast. yes, indeed, i also have a bluetooth setup for the bass shaker - and it works pretty well. For my question, i wrongly formulated it - i meant, for an SMC3 setup using Arduino Uno, i normally connect it through the usb cable to receive the position data. Can i eliminate the cable and go by bluetooth ?

    i am imagining that the latency would be high but I use my platform mainly for flight sims. Not sure what would be the experience.

    And secondly, interfaces such as flypt, simtools or simhub, would they be able to connect via bluetooth ?

    Thanks.

    You could try USB over Bluetooth, so the Arduino can interface with SimTools as it normally would, but I suspect latency may be an issue.

    Another option could be USB over wireless. I currently do audio over wireless after giving up on Bluetooth lag and it has been rock solid.

    Thank you noorbeast, i'll give it a try. I have a space constraint at home and if it works, that would be ideal.
