barx Well-Known Member Licensed User Longtime User Apr 23, 2020 #1 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
