  When I took the ammeter out the program worked flawless.

  I've just turned on the modem, and sent AT, but sometimes it fails because of those messages.

  Shouldn't it be sent only on turning modem up?

  var gprs;
  Bluetooth.setConsole(true);
  var at;
  console.log("Turning Cell on");
  require("iTracker").setCellOn(true, function(usart) {
    console.log("Waiting 30 sec for GPRS connection");
    at = require('AT').connect(usart);
    at.debug();
  });

  ] "\r\n+"
  ] "PACSP1\r\n"
  

  I can't connect to the network anymore.

  It only happens when the SIM card is present.
  What do i do?

  Thanks @Gordon,

  Yes, By serial I mean over Bluetooth. I'm really not sure what's happening.

  RDY is sent when ME initialization is successful. But I never received it before, now i'm wondering, in the GSM/GPRS example, there is a wait of 30 seconds before connecting to GSM.

  var gprs;
  console.log("Turning Cell on");
  require("iTracker").setCellOn(true, function(usart) {
    console.log("Waiting 30 sec for GPRS connection");
    setTimeout(function() {
       // ...
   },30000);
  

  Is it really necessary? Because I ain't doing it.
  Should I wait that long before registering to the network?

  Hey guys,

  everything works fine until some point.
  Then It starts dumping tons of RDY and +PACSP1 on serial that was meant for modem.
  And when it does, there is nothing i can do to stop it, not even reseting the board... I mean, it stops while the modem is down, but once i bring it up it won't stop until i reset the board.

  I do have setConsole set on init. I also run it after boot, this isn't helping.

  Bluetooth.setConsole(true);
  

  I can't run a simple AT command.
  Have you guys seen that behaviour before?
