<![CDATA[Ultrasonic I2C doesn't work with UIFlow2]]>Hello everyone.

Ultrasonic I2C with UIFlow2, measurement result is always -1.
I tested Atom lite, AtomS3, nanoC6, M5Din meter and M5Dial.
Only M5Dial works fine, however other units are not.

This screenshot is AtomS3 but other modules are almost same(Only i2c address is different).

Has anyone been able to get this working properly with AtomS3 or some other modules?

(UIFlow2 version is 2.4.1.)

Thanks in advance.
Yamada
