How to use the same arduino connection in two different apps?

I have an app that uses several object based connections, arduino being one of them. However, I need to open a second app in a callback of the main app and I need to use the existing object based connections (like arduino) in the newly opened app. Any ideas on how to do this?

I have already tried clearing the existing connections and reconnecting, but each time it tells me that the connection already exists in my workspace (despite the fact I just cleared it). I have also tried sharing data between the apps as output/input variables but am struggling to do so and could use a workaround.

Hi Sean,

Unfortunately, directly sharing a serial port connection between multiple MATLAB apps running simultaneously isn't recommended. Serial ports are designed for exclusive access by one application at a time.

You could however try one of the following approces.

1. Single App with communication
2. External Communication Server
3. Multiple Serial Ports
4. Alternative Communication Protocols

Hope this helps!!
