I got some errors.

Rebooting...

Looks like a wiring problem. Please recheck wiring, use appropriate pull-up resistors.

I also ask you to build and flash an I2C bus scanner into your device. https://github.com/UncleRus/esp-idf-lib/tree/master/examples/i2cdev/default

You're right, it's a wiring problem, after adding appropriate pull-up resistors I'm able to read the temp and humidity, but I'm also getting some errors, I did do something wrong?

Edit: I'm using the example code

[aschiavon91]

I have been testing since last comment, and besides those errors, the implementation seems to be working pretty well

[UncleRus]

@trombik Sakurai-san, may I ask you to look into the problem with the driver? At the moment I, unfortunately, do not have the opportunity to program.

[trombik]

@UncleRus will have a look

[trombik]

the datasheet is the one of the worst i have ever read.

[trombik]

@aschiavon91 please test the new example. there should be no warnings or errors.

[aschiavon91]

@trombik seems to be working pretty well now, I left it running for 10/15 minutes and no errors occurred
