I just bought an Opta RS485 for a project. I have been struggling for four days to get the IDE to connect with the Opta and it does not work. I have tried everything and I am on the verge of giving up. Unfortunately I can't sell or return this item as it's not broken.
I have tried all the tricks I found in the different forums:
- I tried QSPI format (both in "heartbeat" mode and normal mode)
- I tried installing the runtime (both in "heartbeat" mode and normal mode)
- I tried a different computer
- I tried switching off all security features (firewall, antivirus, etc.)
- I tried installing and running the IDE "as administrator"
- I tried deleting all the files in folder T
- I tried IDE version 1.0.6 and 1.0.8
- I tried three different kinds of USB cables
- I tried with 24V on and off
- I tried using different combinations of the ports, baud rates and parities.
None of the interventions above worked.
Can someone help please? My project would be impractical if I tried to use the normal Arduino IDE.
If anyone was able to set it up properly, please help.
