Hello,

Has anyone successfully created a project that can communicate (Get & Set) with ModBus RTU

I have already seen this post --> https://www.b4x.com/android/forum/threads/modbus-rtu.115115/#post-719349
but it appears to only be able to set registers. I need to get information. It is to read data from a kWh Electricity Meter.
I have tried to do it with Arduino IDE too but my arduino is even more sketchy (no pun intended) than my B4R.

Cheers

Well, a bit of good news. I've managed to get something working in Arduino.
