  • Hi! What you're doing looks fine - although I'm not sure the console log you posted actually matches the code that you posted up?

    Are you sure you're not calling initGPRS more than once? I don't see it called at all in the code, but if it were called multiple times it would definitely cause a memory leak.

    Looking at the module the Uncaught Error: 0, CLOSED already registered message would seem to be caused by the module not actually sending the line 0, CLOSED when the request finishes. I don't know if that's some difference between the SIM808 and SIM900 or not, but it might be I need to make a few tweaks to the module to get it to handle that properly.

    Please could you run sim.gprs.at.debug(), make a request, then post what gets printed up here?

    Hopefully it'll allow me to make some changes to the module to fix the issue.

  • Hi Gordon,

    although I'm not sure the console log you posted actually matches the code that you posted up?

    Yes I Just clean it up to be easier to see the important data.

    Are you sure you're not calling initGPRS more than once? I don't see it called at all in the code, but if it were called multiple times it would definitely cause a memory leak.

    I am calling it only once manually from the left side of the IDE when the SIM808 is ready - Just for testing.

    AT Debug:

    >sim.gprs.at.debug()
    ={
      line: "",
      lineCallback: undefined,
      handlers: {
        "+RECEIVE": function (b) { ... },
        "+D": function (b) { ... }
       },
      lineHandlers: {  },
      waiting: [  ],
      dataCount: 0 }
