Cannot add second DIY BLE Device

sikrip

Hello all,

I am creating suspension travel measuring devices using nRF52 boards one for each corner.

I am able to connect the first device(named FR_S) but when I am trying to connect the second(named RR_S) I get the following error:

"This would cause a conflict in the device configuration. Following devices must be disabled first: FR_S"

I register the "CAN-Bus filter characteristic" but I have not implemented the write callback method.

Here is my code: https://github.com/sikrip/suspension-travel-can-device/blob/master/main/main.ino

Any idea what I am doing wrong?

Currently RaceChrono allows only one type of this device. There's some "core" changes needed to make this happen. On my TO-DO list.

Thanks!

@sikrip Assuming you just need to log the position of 2 or 4 suspension potentiometers, it might be easier to have one board somewhere, connected to all the potentiometers at once?
Will follow your project, I'm really curious now

@timurrrr what I am trying to do is to log the suspension travel on all 4 wheels. I will use precision potentiometers to do that (for the test phase I am using cheap units):

On top of that, I want to have the ability to log the tyre temps using thermal cameras (to be added later).

So in order to achieve the above, plus the fact that I do not want to route long wires from all 4 corners of my car to one board, I need to have one board per corner.

Last weekend I experimented with the code of https://github.com/MagnusThome/RejsaRubberTrac and adapted it so that:

* it uses a potentiometer for measuring the suspension travel
* it works with the latest MLX90640

Will fork this repo and share my code here.

The good thing about "RejsaRubberTrac" devices is that I can add as many as I need

So @aol_of_RaceChrono my problem is solved for now but it would be nice to have the ability to add more than one DIY BLE Device in RC.

Thanks!

@sikrip Understood. Currently the app "core" has some problems distinguishing between devices of same type. That's something I need to address before allowing adding multiple DIY devices. I need to fix that anyways for the tyre temp sensors.
