Arduino client example for multiple meters

Thanks for fast reply. So basically I must duplicate all Client.init to Client1.init or ret = Client.GetData to ret1 = Client1.GetData. Sorry if this is stupid question.

I will try it tomorrow. I'll report it if i succeed or fail. :) Thanks again.

So I tried to understand code but failed, as I suspected. This is what is bothering me. If I put second meter in void setup:
void setup() {
GXTRACE(GET_STR_FROM_EEPROM("Start application"), NULL);
BYTE_BUFFER_INIT(&frameData);
//Set frame capacity.
bb_capacity(&frameData, 128);
Client.init(true, 1, 145, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);
//Second meter
Client2.init(true, 1, 146, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);

Now how can I call second meter in void loop to read and close connection?

void loop() {
int ret;
if (millis() - runTime > 5000)
{
runTime = millis();
GXTRACE(GET_STR_FROM_EEPROM("Start reading"), NULL);
//TODO: Change logical name of the frame counter if it's used.
ret = com_readAllObjects("0.0.43.1.0.255");
com_close();
}
}

Thanks for code, but yea I am unable to compile. Suprise suprise. I added int meter1 to pass meter1 is not declared in this scope error but then I get Client2 is not declared in this scope.
void loop() {
int ret;
int meter1;
if (millis() - runTime > 5000)
{
if (meter1)
{
//Initialize Meter 1 settings.
Client.init(true, 1, 145, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);}
else
{
//Initialize Meter 2 settings.
Client2.init(true, 1, 146, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);}
runTime = millis();
GXTRACE(GET_STR_FROM_EEPROM("Start reading"), NULL);
//TODO: Change logical name of the frame counter if it's used.
ret = com_readAllObjects("0.0.43.1.0.255");
com_close();
}
//ret = com_readAllObjects("0.0.43.1.0.255");
//com_close();

}
I know you can't babysit me through this code so if anybody has working example on how to read multiple meters with arduino I will be very grateful. Thanks

There is some progress. I can compile and run code like this:
void loop() {
int ret;
if (millis() - runTime > 5000)
{
Client.init(true, 1, 145, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);
runTime = millis();
GXTRACE(GET_STR_FROM_EEPROM("Start reading meter1"), NULL);
//TODO: Change logical name of the frame counter if it's used.
ret = com_readAllObjects("0.0.43.1.0.255");
com_close();
}
if (millis() - runTime > 9000)
{
Client.init(true, 1, 146, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);
runTime = millis();
GXTRACE(GET_STR_FROM_EEPROM("Start reading meter2"), NULL);
//TODO: Change logical name of the frame counter if it's used.
ret = com_readAllObjects("0.0.43.1.0.255");
com_close();
}
}
But it only reads meter with lower millis in this case 5000. I assume this is because millis resets every time when meter1 is read. How can I read one meter every 5 seconds and another every 9 seconds? Any help is appreciated.

So I managed to make it work if I read all meters in same interval.
void loop() {
int ret;
if (millis() - runTime > 10000)
{
Client.init(true, 1, 145, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);
//runTime = millis();
GXTRACE(GET_STR_FROM_EEPROM("Start reading meter1"), NULL);
//TODO: Change logical name of the frame counter if it's used.
ret = com_readAllObjects("0.0.43.1.0.255");
com_close();
delay (200);
Client.init(true, 1, 146, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);
runTime = millis();
GXTRACE(GET_STR_FROM_EEPROM("Start reading meter2"), NULL);
//TODO: Change logical name of the frame counter if it's used.
ret = com_readAllObjects("0.0.43.1.0.255");
com_close();
}
}
I've added small delay between meter read because sometimes I get unable to initialise connection on second meter. Probably because esp32 still receives something from first meter. Also I comment out runTime = millis() in first meter and leave it on second. Can those two changes make some problems in code.Thanks.
