B4A Modbus RTU: Implementing Industrial Communication in Android Apps

B4A (Basic4Android) is a Rapid Application Development (RAD) tool for Android development. It allows developers to create Android applications using a language similar to Visual Basic. \n\nModbus RTU (Remote Terminal Unit) is a communication protocol commonly used in industrial automation systems. It allows communication between a master device (such as a computer) and multiple slave devices (such as sensors or actuators) over a serial communication interface, typically RS-485. \n\nTo implement Modbus RTU communication in B4A, you would need to use a library or module that provides Modbus RTU functionality. There are several third-party libraries available for B4A that can be used for this purpose. These libraries typically provide functions for sending and receiving Modbus RTU messages, decoding the received data, and handling communication errors. \n\nYou can search for Modbus RTU libraries for B4A on the B4X community forums or on other online platforms. Once you find a suitable library, you can follow the library's documentation or examples to integrate it into your B4A project and implement the Modbus RTU communication logic.
