It is because GPIO has a pull up resistor fitted on the RPi board - it can be used for I2C. Try changing to a non-I2C pin and that should fix it. Thanks! Perfect, I switched to another one and it worked. I see now in the specs "i2C pin SDA includes a fixed, 1.8kO pull-up to 3.3v, which means this p...

I will start explaining a little bit about the project. It is a simple PIR sensor with a webcam and a 7 segment display. The sensor catches movements, the webcam makes a photo, I add a row into a .csv file and the display counts how many times a movement was registered. The picture is saved into a f...

You are right. I downgraded to the latest master firmware and opened an issue in the github. They suggested to open it in the kernel project. Thanks again for your effort. At least it is clear what is the problem and how to resolve it. So far it is not critical in my case, I can change the running c...

OK. I'm stuck. I've no idea why your RPi3B won't play nicely with your AP. It's probably time to report it on https://github.com/raspberrypi/firmware and see what the nice folks at the RPF make of your problem. thanks for your time and advice. I checked again from the beginning and using the hash f...

Have you used sudo raspi-config to set your WiFi country code?

Yes, I switched the country code to DE - Germany.
If I check the wpa config it shows the correct one.

Running only from channels 1-11 appears.

Same problem here. I connected through ethernet so I could update the system. After that now it is even worse. The default gw is not being recognized for eth0 and the wlan0 continues without finding my SSID. Wifi is set to my country. Wifi is set to channel 7 Wifi 5Ghz is set to channel 40 Any idea?...
