reading UART port on Raspberry Pi 3 using IoT-edge

Question

I'm using IoT-Edge on my Raspberry Pi 3. Since IoT-edge isn't compatible with Windows 10 IoT Core on Raspberry Pi 3, my Raspberry is on Raspbian.

I'm trying to read my UART ports to read XBee sensor data.

My edge's modules are written in C# thus far.

I'm using Raspbian so I can't use the class System.IO.Ports.SerialPort since System.IO.Ports is only compatible on Windows system. Is there another way to read my UART ports inside my module? (I'm ready to write a module in something other than C# if I can deploy it the same way.)

If not, is there at least a way to read/write data from a shared file between containers/raspberry without manually changing docker container file binding mode each time we deploy a module version (since the default binding mode for docker container is read-only, but my Raspberry will have to send data to sensor too)?

Answer 1

You are right about .NET Core not supporting serial on Linux. The latest version of the Python SDK is ready to write Edge modules. We are working on a sample and development guidance on using it, but that's not out yet. Once we have the sample/guidance out (hopefully soon), you should be able to write your module in python and read/write from the serial port. I've confirmed that it works in an Edge container.

Answer 2

You can use .Net Core to read UART ports. .NET Core is a cross-platform, it supports Raspbian,and applications can be written in C#.You can refer to this topic about how to use System.IO.Ports.SerialPort in .Net Core.
