I2C error encountered during I2C transmit hook execution

[Srihari]

@RobLauer I have been using notecard for one year and facing I2C errors since 2 days.
I don’t see data in Notehub and not whether it is issue with ESP32S3 MCU or Notecard.

I tried sample sketch “Example1_NotecardBasics.ino” and see below errors.

14:30:47.605 → [ERROR] error encountered during I2C transmit hook execution

14:30:48.599 → [ERROR] i2c: received NACK on transmit of address {io}

Hey @Srihari,

Sorry you ran into issues here. Could you show us how you have your Notecard and MCU connected? And also could you let us know what version of Notecard firmware you’re using?

Thanks,
TJ

It seems to be nothing communicating and tried to reset. I think the notecard not responding on the I2C.
