Hi,
I put all on a soldering breadboard now and also added 2.2k resistors to the I2C SDA and SCL lines and 3.3V. I checked it with my oscilloscope and the signal looks better now (less noise + more squary like). But still the same issue, the floating fix stops after some seconds / minute(s) … but I still get a valid correction signal and I’m still transmitting it to the receiver.
So, question again … how can I debug this? Or what can cause this issue?
greetings and thanks,
André
