External IMU and Bluetooth

I have an older VESC without internal IMU, and I am building a one wheel. I really want a Bluetooth connection.

I was thinking about:

  • With an Arduino or Teensy recode CAN to UART for the Bluetooth module. Have anyone tried this before? Is there any technical limitation to do that?
  • It is possible to connect the IMU via CAN?
  • Or is it possible to change the firmware to use the CAN (or any other) ports as I2C/UART without conflicting each other? Because I need only HALL sensor, ADC1, ADC2
  • I read about the UART splitter, but the IMU is I2C. And I couldn't find anything to use the same port for them.

Any help would be greatly appreciated. Thank you in forward!

Which VESC do you have? Some have the footprint but the IMU is simply not placed.

I have only a version 4. As far as I checked there is no place for the IMU.
