windows iot serial communication

Question

I am working with windows 10 iot and raspberry pi 2 mode B. I need to make a serial communication between my raspberry and an arduino. This is possible? do you have any example please?

Answer 1

Hello @ALFREDO LANDERO SANCHEZ ,

For IoT, reading data over a serial connection and sending that to the cloud is another protocol.

This is also the case with Linux.

First, check if your serial device is accessible in the /dev folder.

Try to read the data from that serial port depending on your programming language. (eg. in .Net core (C#), check out the serial port class)

If you want to use Azure IoT Edge, this open-source project on GitHub is a good starting point.

There, you will notice you have to give the Docker container to the serial port (because Docker containers are sandboxed by default)

You can use the Windows.Devices.SerialCommunication name space in your application to create serial communication. Here some code to send a message:

        string aqs = SerialDevice.GetDeviceSelector("UART1");  
        DeviceInformationCollection deviceInfo = await DeviceInformation.FindAllAsync(aqs);  
        SerialDevice myCom1 = await SerialDevice.FromIdAsync(deviceInfo[0].Id);  
        myCom1.BaudRate = 9600;  
        myCom1.DataBits = 8;  
        myCom1.Parity = SerialParity.None;  
        myCom1.StopBits = SerialStopBitCount.One;  
        myCom1.Handshake = SerialHandshake.None;  

         DataWriter dataWriter = new DataWriter(myCom1.OutputStream);  
         dataWriter.WriteBytes(<your message>);
