Hello LEOMENA, as you already pointed out the problem is very likely the fact, that your program needs the graphical environment. The revpipyload is designed to run your program in background as a system service which is completly decoupled from the session which is started by the graphical environm...

Hi garysn, there is no Delphi library as far as I know, but you can probably access the process image directly via /dev/piControl. For some examples have a look into the article about using with C: https://revolutionpi.com/picontrol/?noredirect=en_US Using ioctl with lazarus: https://www.freepascal....

Hi jce, I remember a similar experience with devices running older image as you do. Please update to our latest image (buster) as your release has already two successor releases (stretch and since a few months buster). You can find the instructions in our tutorial section: https://revolutionpi.com/t...

Hi Joca, please have a look at our tutorials regarding the configuration of our (virtual) Modbus modules: https://revolutionpi.com/tutorials/modbus/?noredirect=en_US. For Modbus RTU you will need either a RevPi Connect with an integrated RS485 interface or a Core3 with an external USB to RS485 adapt...

Hi rishadahmed,

I'm afraid there is no WWAN ready RevPi or extension module, yet. As far as I know this is on the (future) roadmap, but without any date. My suggestion would be to use an industrial Router like the Teltonika RUT950 or if space is a criteria the RUT240.

Das EOL für Buster wird wohl in 2022 liegen. Danach gibt es aber für gewöhnlich noch ein paar Monat / Jahre LTS Support.

Hallo Markus,

mit der Abhängigkeit gebe ich dir recht. Die verwendetete PHP Version richten sich nachdem, was durch das jeweils zugrundeliegende Debian Release bereitgestellt wird. Das ist im Falle von Buster 7.3. Eine neuere Version wird es wohl erst mit Bulls Eye geben.
