S1 is not axeptated by GUI

Great to hear that worked out!

Can I use Odrive GUI on the Ipod to get mobile data?

Can I use Odrive GUI on the Ipad to get mobile data.

Probably not, unless Apple supports WebUSB on their devices, but I don’t imagine they do. If anyone wants to test, I’d love to hear the results!

Is there any other way to document the engine data on a mobile machine while driving?

Sure! Some solutions:

  1. You could use an Arduino or Raspberry Pi connected to the ODrive over UART or CAN, reading the parameters and displaying them on a screen, something like this for the Arduino or this for the Raspberry Pi.

  2. You could use an ESP32 or Raspberry Pi to read the data from the ODrive over UART or CAN Bus, then make a web app that you’d open up on an iPad or similar to view the data. You could also do this over Bluetooth, and write the app for the iPad.

  3. You could use a cheap Windows tablet like this to just run the GUI directly, connected to the ODrive over USB.

The Hall sensors failed for me. I can also operate the motors in sensorless mode. and if so, how

In the GUI I didn’t find a setting for sensorless

How did the halls fail? What was the error?

Sensorless is a bit more of an advanced mode, and doesn’t support features like direction switching (requires some external logic to do so), so we don’t have it shown in the GUI by default. However, the inspector tab has full functionality and control over the ODrive, you can see docs here: Hardware Configuration — ODrive Documentation 0.6.10 documentation

I suspect thermal overload.A sensor has failed. Can I also work with one or 2 sensors

No, you definitely need all three sensors. If you could post a picture of your wiring, happy to see if it’s possibly an issue there. How did you diagnose that the sensor failed?

With a multimeter
A 4V 0V
B 4v 0V
Z 3.7V 3.7V

Understood. Maybe it’s worth getting a new motor?
