I2C communication with non-existing slave

[David_D]

Hi. I'm trying to send a message to a non-existing slave via I2C on SPC58EE84E7.

Is this possible?

I get a NACK error message in response.

Are there any examples of such an implementation?

Thank you!

NACK means that the SDA line stays high. This is the default SDA state (pull-up) and therefore you get the NACK if no slave aknowledges your request. This is expected behaviour.
