@craigweb I think this protocol is important. And many hardware supports this protocol. Does Mango have a timetable to support this?

Or is there a way to indirectly support the hardware of this protocol?

Or is there a manual support method? Now I have passed c# to Read and Write my hardware.

I was not so clear with this thing, but it do solved!

here is my solution:
"connectionUrl":"jdbc:mysql://localhost:3306/test",
"driverClassname":"com.mysql.jdbc.Driver",

Note: replace "localhost" "3306" "test" if needed.

@craigweb thank you !
this problem solved!
