Summary: enhance connectors.serial - missing things?
Key: EDGENT-411
URL: https://issues.apache.org/jira/browse/EDGENT-411
Project: Edgent
Issue Type: Improvement
Components: Connectors
Reporter: Dale LaBossiere
Serial connector seems to be adding a bit of structure for a cmd
request/response protocol to a SerialDevice that's attached to a system via a
SerialPort.
It's hard to make sense of it until seeing it used in
samples.connectors.elm327.Elm327Streams (and elm327.runtime) and
sample.connectors.odb2.Obd2Streams - that is, a particular cmd request/response
protocol to a device connected via a serial port. And there's no sample
implementation of SerialDevice or SerialPort in the repo.
At a high level it strikes me that the SerialConnector should offer a general
SerialDeviceStreams at the conceptual level of the of Elm327Streams. And we
really need some doc (or sample) of a SerialDevice/SerialPort.
And what about a non-periodic (non-poll) form of non-static cmd list
invocation? e.g., sending commands in a TStream - something like {{static
TStream<JsonObject> sendCommands(SerialDevice, TStream<Cmd>)}}.
And maybe there are other forms of use of a serial device - e.g., maybe the
device/port just emits records on its own, not a bounded response to a "cmd".
