We are currently experimenting ubuntu core on a Dell Edge 5000 , the device comes with 4 serial ports (3 RS485 and 1 RS232) and 3 USB ports .
The snap needs access to these serial ports (including USB) , From the interface documentation , it is mentioned that
serial-port interface needs to be used but there is also a mention that a gadget needs to be available providing the slot. I could not get any gadgets for DELL 5000 that provides these slots (may be they are private) . The documentation for creating gadgets looks to be a “too much” work for a snap developer (which of-course would be a last resort ) .But just to get the things rolling , are there any ready to use generic gadgets which would provide access to the available serial ports on any device ?
I really do not know the rationale behind not having this feature supported by the core snap.
Thanks in advance.
