hello,
I'm trying to connect Arduino to Secure Premier 300 using GuruxDLMS Arduino library. I was successful to compile and flash the program. But, I got received bytes : 0, data send failed, trying to resend 3 times and com_initializeConnection failed 252.
I have set parameters in Client.init() in void setup() following device configuration in Gurux DLMS Director (I was successful connect and read data to the meter using DLMS Director with this config). Is there anything I missed?
Thank you.
Hi, Check your settings…
Hi,
Check your settings. Specially baud rate. Arduino is using 9600
Serial.begin(9600);
Try to first without authentication.
Client.init(true, 16, 1, DLMS_AUTHENTICATION_NONE, NULL, DLMS_INTERFACE_TYPE_HDLC);
After that succeeds you can try with MR.
Client.init(true, 16, 1, DLMS_AUTHENTICATION_LOW, "YOUR_PASSWORD", DLMS_INTERFACE_TYPE_HDLC);
BR,
Mikko
