Cannot enqueue Handshake after invoking quit

Question

I have implemented the following code:

module.exports = {
    getDataFromUserGps: function(callback)
    {
        connection.connect();
        connection.qu         


        

Answer 1

inplace of connection.connect(); use -

if(!connection._connectCalled ) 
{
connection.connect();
}

if it is already called then connection._connectCalled =true,
& it will not execute connection.connect();

note - don't use connection.end();
