steveohara/j2mod integration #233

Closed 44simon closed 5 years ago

44simon commented 5 years ago

Hello, thanks for such a great library. I have found steveohara/j2mod thing and I want to run a serial RTU master with your library. I have sucesfully ran an example with the FTDI device - it is detected and works just fine. Do you happen to have some examples how to do this using your library and steveohara/j2mod?

Thank you so much in advance, Simon

Hi @44simon Actually I tried to integrate j2mod with UsbSerial but I became distracted. Sadly there are no examples as far as I know. Maybe it's time to fork and maintain an Android version with UsbSerial and gradle with the shared code with J2mod. I will think about it

I can help you with testing and documenting.

@44simon That would be great! I will keep updated this issue

@44simon I just created a repo with a really rushed first version of an integration between j2mod and UsbSerial https://github.com/felHR85/AndroidModbus It contains two modules. The library itself and an example app. Example app managed to send some data using this:

modbusSerialMaster.writeCoil(1, true);

but I guess this waits for a response and it is blocking the main thread. My modbus knowledge is basic so it would be nice if you could test proper Modbus communications with this.
