Newbies: Help for application Android Modbus RTU in serial USB

  • Dear all,
    It 'the first time I program in Android, so I'm no expert.
    I use Android Studio, and I would use the modbus4j library to communicate in Modbus RTU Master with a tablet (Android) through the USB port, ie serial 9600 baud.
    (The tablet would be the Modbus RTU Master)
    I would like to read and write Holding register, coils and register input.
    There 's someone who can help me configure the project, so give me a start?
    Thanks in advance.

  • Looks like you and I are trying to do the same thing.

    It seems that your simply looking to poll modbus registers, and write them.

    Here's what I found.

    There are two types of groups.

    Group one are experts at doing just this.
    Group two are experts at taking the data and putting it on a slick graph.

    I spent 6 months on this same project last year, only to get frustrated and quit.

    I think we should collaborate.

    Drop me an email response.
