I'm opening this new thread about the Opta board because all the others are about a different kind of board. I bought an Opta Lite to develop a project that transforms some industrial input into web calls. The project is now ready and working in my environment, but I'll need to update the sketch with new features in the future.
I would like to update the sketch through an Ethernet connection because it is very difficult to access the electric panel where Opta is mounted, but I cannot find any suggestions.
Is there any official way to do it?
Thanks to all of you for suggestions!!
Hi PMarquinez
Thanks for reply
Yes I use Arduino IDE, I worked with some board where was possible to connect the IDE directly by Ethernet or wifi to the board and push the sketch in, but i cannot find that way with OPTA and i dont understand if this is an wanted limitation or something else.
Thanks a lot
Maybe i don't understand something but can you please elaborate more on how to upload a simple sketch via ethernet and without the IoT cloud but on the Arduino IDE? From what i can see, i only have COM port to do that.
Many thanks,
Marco
Hello @PMarquinez,
thanks for the info, i already knew about the OTA but we need to serve these PLCs on some clients that they don't want to pay the subscriction for the Cloud services (at the moment, we need at least 5 PLCs so out of the free tier).
Sorry to ear this, i'm a bit disappointed on this point if the target of the Opta product is the industry sector.
Regards,
Marco
Hi @PMarquinez can I use a hosted .ota file to update the Opta with an entire Arduino PLC IDE Project?
Also my understanding is that at present updating the sketch via Arduino Cloud does not allow the use of PLCIn and PLCOut functions is this correct?
