Hi,

We are using the I2C sniffer at 50kHz. I am getting the '-' sign, [0xC3-] from the master. What does this means?
I have also seen some posts where there is a '+' sign, is this normal?
Any way to control the device, emulate the master to control the slave.

attached the full device ID.
Device is discovered at 50kHz when master is disconnected.
Warm Regards.
