hi
i am unable to communicate with meter using esp3.
i even changed this function .
Client.init(true, 32, 1, DLMS_AUTHENTICATION_LOW, YOUR_PASSWORD, DLMS_INTERFACE_TYPE_HDLC);
the error i am getting is
com_initializeConnection failed
in the code exactly at this logic
//Initialize connection.
ret = com_initializeConnection();
if (ret != DLMS_ERROR_CODE_OK)
{
Serial.println("INSIDE DLMS_ERROR_CODE_OK");
GXTRACE_INT(GET_STR_FROM_EEPROM("com_initializeConnection failed"), ret);
return ret;
}
any one please let me know where i am doing wrong.
Hi, Your settings look…
Hi,
Your settings look correct. Check that your UART is connected correctly. Check baud rate, etc. serial port settings. Check also your wirerings. That is the most common reason for this.
Try to first connect with GXDLMSDirector. I believe tit will help you to get started.
BR,
