GoFree Web Interface 5.1 Requesting a list of data IDs - C2S The client can request a list of data IDs. Digital data values are grouped so a client can request all the data IDs in a group ( e.g. request all engine data ). The groups are detailed in Section 11. {"DataListReq":{"group":1}} group = The - Lowrance HELM-1 Drive Unit | GoFree Tier2 Toolkit View Only - Page 6
GoFree Web Interface id = The ID of the data repeat = Should the data repeat, or be sent only once. This is an optional parameter that defaults to false. If set to true then the server will periodically send the data to the client whilst the WebSocket connection remains open.
