A flashing red LED indicates Range error. A too high a voltage or too high a power supply at one or more inputs. Check the input status in the process image. https://revolutionpi.com/en/tutorials/uebersicht-aio-2/status-leds-revpi-aio-2 What is the voltage of the connected sensor? Could you please s...

Hi

Could you please test if the following fixes the problem for you?

1. Download the attached archive and extract it
2. Copy the file to your revpi as `/boot/dt-blob.bin
3. Reboot

If you're using ferrules (depending on the crimp pattern) it can be sometimes helpful to twist a little while pulling.

Hi Christian, wenn du ohne extra Routen aus dem einem Netz auf einen bestimmten Port (z.B. vom Webinterface) eines Gerätes im Sensornetz zugreifen willst, würde ich mit Portweiterleitungen arbeiten. So aus dem Kopf: iptables -t nat -A PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 192.168.0...

Thanks for letting us know. Probably this will help other users upgrading.

The value in process image is of type integer. Multiplier and Divisor are applied to the same integer feld, thus no decimals If you want to have a float value, I suggest to do the processing in your application.

You get call piTest with `-1` and it will return asap the value has been printed. I guess the ~45 secs are result of your timer

The above posted /boot/config.txt gave it away: The dtoverlay=revpi-core is missing, so the device did not know which pins to connect to what. Thus nothing really will work (eg. piSerial which relies on the crypto chip). The overlay is usualy set during factory reset which you might omitted with the...

Hi

From which version did you upgrade to Bullseye and how?

Looks like the security chip is not initialized. Could you please share the content of dmesg and /boot/config.txt.

Which version of revpimodio2 are you using? /etc/revpi/config.rsc should be a symlink to /var/www/pictory/projects/_config.rsc (on Stretch) or /var/www/revpi/pictory/projects/_config.rsc (on Buster and upwards). NOTE: Pictory version 1.4.7 is (very) outdated, thus you must be using an outdated versi...
