Problem with Ultrasonic I2C

[maiknaef]

Hello everyone,

I am new to M5Stack.

I have a Core 2 and the Ultrasonic i2c connected to it. Now I have the problem that the value on the Core 2 always shows -1. Am I doing something wrong when setting it up?
Connect, select unit, then insert the blocks, upload code.

Thank you in advance for your help.

@maiknaef Hello.
I have same problem with AtomS3, nanoC6 and Atom lite and Din Meter.
However M5dial works fine. I tested Uiflow2.4.0 and 2.4.1.
It is strange because M5dial and M5Din meter are uses StampS3.
Sorry I have no idea at this moment, however hopefully it solved in future.
