Error - Index 23 out of bounds for length 23

Good morning, I am using the suntech st3300r devices, but they do not appear in line and it marks the next error in the log.

I hope someone can help me.

Regards.

From what I can tell, the message is invalid. Do you have the protocol documentation? Try to do a manual breakdown.

I'm new, I don't have the device documentation. the device I am using is

https://suntechlatam.com/producto/ST3300R?fbclid=IwAR2y6wllceGFXfFyp94hOjwKQ77CqaQ45krAxO3aMm4Am9ftK8KVKn6hymE

You would have to request the documentation.

this is the documentation

https://fccid.io/WA2ST3300/User-Manual/User-Manual-4260066

Now you can try to break down your sample and see if it matches.

suntech st3300r devices

I think the problem is at the end of the message. As you can see, there are some empty fields there.

How can it be possible, if you have the same configuration all 3 devices

Well, that's a question for your device vendor.
