ServiceError

Hey!
I am able to read registers and meter responds as required. But after 1 loop i am getting a service error.
This is the code i used in arduino :

gxRegister voltageL1;
void loop() {
for(int i=0; i<2; i++)
{
int ret;
//Initialize connection.
ret = com_initializeConnection();
ret = com_read(&voltageL1.base, 2);
ret = com_read(&voltageL1.base, 3);
Serial.println("\n L1 Voltage = ");
Serial.print((int)voltageL1.value.llVal * pow(10, (int)voltageL1.scaler)); // Voltage L1
com_close();
}
while(1)
{ ; }
}

Response form the meter as follows :

Hi,

There are no client requests on the trace, but it seems that you are not calling AARQRequest to establish the connection. Are you established a connection before the loop?
